    INTRODUCTION: Inappropriate use of antibiotics has led to antimicrobial resistance, a major public health challenge worldwide. This study aimed to explore beliefs, knowledge, and practice on antibiotic use among general public.

    METHODOLOGY: Cross-sectional study was conducted at 13 hospitals and 44 primary health clinics in Perak from May to July 2017. Adults above 18 years, literate, and had experience in antibiotics consumption were selected through sequential sampling method. Data was collected using a self-administered questionnaire which included the three study domains i.e. belief, knowledge and practice. The questionnaire was pilot on 30 subjects.

    RESULTS: Out of 2850 distributed questionnaires, 2773 returned and 2632 were included for analysis. Mean age of the respondents was 39.7 ± 14.5 years old. Most respondents were female (58.6%), Malay (74.7%) and underwent upper secondary school (45.6%). Mean score were generated for each domain with belief: 5.87 ± 3.00 (total score: 12), knowledge: 15.82 ± 3.85 (total score: 24), practice: 6.91 ± 2.07 (total score: 12). In the belief domain, 63.2% of respondents believed that antibiotics would help them to recover faster. In the knowledge domain, 52.7% of respondents inappropriately thought that antibiotics could work on viral infections. In the practice domain, 70% of respondents expected doctors to prescribe antibiotics if suffered from symptoms.

    CONCLUSION: Majority of the respondents expect doctors to prescribe antibiotics for their illness, and most believes that antibiotics can speed up recovery of illness. Lack of awareness on antibiotic resistance was found to be a significant factor associated with inappropriate antibiotic use.

    INTRODUCTION: Farmworkers are considered a high-risk group for tick-borne diseases (TBDs). This qualitative study aimed to gain an in-depth understanding of the farmworkers' experience, knowledge, health beliefs, information needs, and preventive practices of tick bites and TBDs.

    METHODOLOGY: A total of nine focus group discussions with 56 farmworkers across eight animal farms in Peninsular Malaysia were conducted between August and October 2013.

    RESULTS: Farmworkers explained their experience of tick bites, but no one reported TBDs. Many farmworkers indicated that they did not seek any medical treatment. There was a misconception that ticks are solely pathogenic to farm animals. Farmworkers perceived low severity and susceptibility of tick bites, and low self-efficacy of tick bite prevention, however, a group also perceived susceptibility to getting tick bites due to the characteristics of their job. Barriers for prevention were related to the perception and knowledge towards ticks. Farmworkers requested information about TBDs.

    CONCLUSIONS: This study of farmworkers identified gaps in the knowledge of TBDs, barriers of the tick bite preventive measures and information needs. These findings suggest a need for education programs to improve the knowledge of ticks and TBDs, change health beliefs and address the barriers of tick bite preventive measures.

    INTRODUCTION: The latest revised version of the World Health Organization's dengue classification was released in 2009. A handful of studies have taken initiatives to evaluate the old and revised guidelines to determine early signs and symptoms of severe dengue. This retrospective study aimed to compare the classification of dengue using both the 1997 and 2009 guidelines in a selected cohort of dengue patients from Peninsular Malaysia between 2008 and 2012.
    METHODOLOGY: Adult dengue patients were recruited from tertiary hospitals in two different states, Selangor and Kelantan, in Peninsular Malaysia. Their clinical manifestations were assessed.
    RESULTS: A total of 281 confirmed dengue patients were enrolled; the mean duration of illness at admission was five days. Of these, 88.6%, 10.7%, and 0.7% were classified according to the 1997 guidelines as having dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS), respectively. When the WHO 2009 guidelines were applied, 17.1%, 78.3%, and 4.6% were classified as dengue without warning signs, dengue with warning signs, and severe dengue, respectively.
    CONCLUSIONS: Our data suggests that the revised WHO 2009 guidelines stratify a much larger proportion of patients into a category that requires a higher level of medical and nursing care.

    INTRODUCTION: The prevalence of tuberculosis (TB) remains alarmingly high in developing countries, including Malaysia. Recognised as the leading global infectious disease, untreated TB can be fatal. TB is easily spread through the air, and any close contact with a TB patient can put others at risk. This study therefore aimed to investigate the level of awareness of TB among TB patients and how their attitudes affect self-preventive healthcare.

    METHODOLOGY: This cross-sectional study was conducted using a validated self-administered questionnaire at 18 hospitals in six states of Malaysia, namely, Selangor, Kuala Lumpur, Penang, Kelantan, Sabah, and Sarawak in 2015. The study sample comprised 1600 TB patients who were randomly selected using data obtained from the Disease Control Division, Ministry of Health Malaysia. A total of 1368 of the completed questionnaires were considered usable and included in the statistical analysis.

    RESULTS: Overall, the level of TB awareness was found to be high, and the respondents possessed positive attitudes towards TB and health-seeking behaviours. Self-preventive care among the TB patients was determined as being at a moderate level. With regard to contact with others, the patients were more comfortable around their families than their friends and neighbours.

    CONCLUSIONS: More health education programmes are recommended to cultivate positive attitudes towards TB, to encourage communities to have a better understanding of TB, and to create awareness among patients of the proper ways to practice self-preventive care.

    INTRODUCTION: The widespread and inappropriate use of broad-spectrum antibiotics in surgical prophylaxis has led to reduced treatment efficacy, increased healthcare costs, and antibiotic resistance. This study aimed to explore the adherence of antibiotic usage in surgical prophylaxis to the national antibiotic guideline and the incidences of surgical site infection (SSI).
    METHODOLOGY: A three-month prospective observational study has been conducted in the surgical wards of Sarawak General Hospital (SGH) using a standardized surveillance form. Each patient was reviewed for up to 30 days post-operatively to determine the occurrence of SSI.
    RESULTS: A total of 87 patients were included within the study period. The majority of the cases were clean-contaminated wounds (60.9%). Most were hepatobiliary cases (37.9%), followed by colorectal cases (19.5%). The most preferred antibiotic used was cefoperazone (63.2%). The choices of antibiotics in 78.2% of the cases were consistent with the guideline. Around 80% of prophylactic antibiotics were given within one hour before operation and 27.6% were omitted from intraoperative re-dosing. Prophylactic antibiotics were discontinued within 24 hours post-operatively in 77% of the cases. Of those continued for > 24 hours, the majority (60%) were administered for unknown reasons. SSI was documented in 13.8% of the total cases studied. However, there was no significant association between choices of antibiotics and timing of surgical prophylaxis with SSI (p = 0.299 and p = 0.258 respectively).
    CONCLUSION: Overall guideline adherence rate was more than 70%. Areas of non-concordance to the guideline require further investigation.

    INTRODUCTION: Studies exploring the appropriateness of therapeutic antibiotic use among surgical patients are limited, particularly in developing countries. Therefore, the aim of our study was to determine the appropriateness of antibiotics prescribed in a surgical setting in Malaysia.
    METHODOLOGY: A prospective observational study was conducted in two surgical wards at a tertiary hospital in Malaysia from November 2012-July 2013. Data was collected using a case report form. The appropriateness of antibiotic therapy was based on compliance with either the Malaysian National Antibiotic Guidelines 2008 or International Clinical Practice Guidelines and determined by an expert panel (consisting of two infectious disease consultants and a pharmacist).
    RESULTS: Over the study period, a total of 593 antibiotic courses were prescribed for 129 patients (4.6±3.4 antibiotics/patient). Only 34 (26.4%) patients received appropriate antibiotic therapy, whilst 95 (73.6%) patients received at least one course of inappropriate antibiotic therapy. The prevalence of inappropriate antibiotic use was 214 (66.3%) and 55 (42.0%) for prophylactic and therapeutic purposes, respectively. The most common causes of inappropriate prophylactic antibiotics were inappropriate timing 20 (36.4%) and inappropriate duration of prophylaxis 19 (34.5%). In cases of inappropriate timing, 9 (45%) were administered too late while 6 (30%) were too early. In contrast, inappropriate choice of antibiotics (42.1%) and inappropriate indication (40.7%) were the most common reasons encountered for inappropriate therapeutic antibiotics.
    CONCLUSION: Our study suggests considerable inappropriate use of both prophylactic and therapeutic antibiotics in the surgical wards; highlighting an urgent need for antibiotic stewardship initiatives in this setting.

    INTRODUCTION: The widespread use of highly active antiretroviral therapy (HAART) and continuous reports of HIV-1 strains developing resistance to these drugs is rather alarming, as transmission of resistant viruses to newly infected persons is possible. This study aimed to determine HIV-1 subtypes and the prevalence of primary mutations associated with antiretroviral (ARV) resistance among treatment-naive prisoners on the east coast of Malaysia.
    METHODOLOGY: Viral RNA was extracted from plasma samples of 21 treatment-naive prisoners. Protease (PR) and reverse transcriptase (RT) regions were amplified and sequenced. Stanford HIV database algorithms were used for interpretation of resistance, and phylogenetic analysis was performed for subtype assignment.
    RESULTS: In the PR gene, no antiviral resistance-associated mutation was detected. For RT-associated mutations, K103N was the most prevalent in sequenced samples (14.3%). Genetic subtyping on the pol gene revealed that the majority of the prisoners were infected with subtype CRF33_01B (52.4%).
    CONCLUSION: Continuous surveillance of newly infected individuals is required to help strategize the best antiviral treatment for these patients.

    BACKGROUND: Differentiation of Salmonella enterica into its serogroups is important for epidemiological study. The objective of the study was to apply a multiplex PCR targeting serogroups A, B, C1, D, E and Vi-positive strains of Salmonella enterica commonly found in Malaysia. A separate H-typing multiplex PCR which identified flagellar antigen "a", "b" or "d" was also optimized to confirm clinical serotypes, S. Paratyphi A and S. Typhi.

    METHODOLOGY: Sixty-seven laboratory Salmonella enterica strains were tested. Six sets of primers targeting defined regions of the O antigen synthesis genes (rfb gene cluster) and Vi antigen gene (viaB) were selected and combined into a multiplex PCR for O-grouping. Four primers (H-for, Ha-rev, Hb-rev and Hd-rev) were used in the second step multiplex PCR for H-typing. The optimized mPCR assays were further evaluated with 58 blind-coded Salmonella strains.

    RESULTS: The multiplex PCR results obtained showed 100% concordance to the conventionally typed serogroups. Validation with 58 blind coded Salmonella strains yield 100% accuracy and specificity.

    CONCLUSION: Based on this study, PCR serogrouping proved to be a rapid, alternative method for further differentiation of Salmonella enterica.

    INTRODUCTION: Antibiotic resistance is a rapidly emerging problem. A major concern is methicillin-resistant Staphylococcus aureus (MRSA), especially in developing countries where cost-effectiveness is imperative. Restriction of vancomycin usage is necessary to reduce the emergence of vancomycin-resistant organisms. The aim of this study was to look into the appropriate use of vancomycin based on the Healthcare Infection Control Practices Advisory Committee (HICPAC) guidelines and to investigate serum levels of vancomycin.
    METHODOLOGY: The study was performed retrospectively. Medical records of patients treated with vancomycin for the past year were identified and selected.
    RESULTS: Overall, 118 patients were treated with vancomycin. Appropriate use of vancomycin was significantly higher than inappropriate use (p = 0.001). Approximately 85% (n = 100) of patients were given vancomycin for treatment, whereas the rest were given it for prophylaxis. Appropriate use of vancomycin was observed in 67% (n = 79) of patients. However, there was still a high rate of inappropriate vancomycin use for prophylaxis and treatment (n = 39, 33.1%). The most common reason for inappropriate use was non-neutropenic and non-line related sepsis (n = 36, 30.8%). Therapeutic drug monitoring of vancomycin was performed in 79 patients (67%). Most patients (n = 53, 67%) demonstrated sub-therapeutic levels during the first measurement. There was no significant difference between trough levels achieved with a higher (> 15 mg/kg) versus a lower dose (< 15 mg/kg).
    CONCLUSIONS: This study demonstrates that there was still a high level of inappropriate vancomycin use, which could potentially contribute to vancomycin resistance.

    INTRODUCTION: The World Health Organization (WHO) declared the Ebola virus disease (EVD) epidemic to be a public health emergency of international concern. Healthcare workers (HCWs) are at the highest risk of infection, as they may come into contact with patients' blood or fluids. This study was conducted to assess knowledge and attitudes of HCWs towards EVD in India.
    METHODOLOGY: A descriptive, cross-sectional study was conducted in a multispecialty public sector referral hospital of Telangana, India. Knowledge and attitude of HCWs were evaluated using a pre-validated questionnaire. A sample of 278 participants was selected to participate in this study. The Chi-squared test was used to assess the relationship between attitudes and demographic characteristics. Logistic regression was used examine the association between knowledge and study variables.
    RESULTS: Of 257 participants who responded (92.4% response rate), 157 (61.1%) were females. The majority of the respondents were physicians (n = 117, 45.5%). Radio and television were the major sources of information about EVD reported by participants (89%). Overall knowledge of HCWs was poor (mean knowledge score: 6.57 ± 2.57). Knowledge of physicians and experienced workers (≥ 10 years) was significantly higher than their respective groups. The overall attitude of the participants was positive (mean attitude score: 1.62 ± 0.57). Significant positive correlations between knowledge and attitude were observed.
    CONCLUSIONS: The findings indicate that participants lack basic understanding of EVD. We recommend future studies be conducted across India to identify and subsequently bridge the knowledge gaps among HCWs.

    BACKGROUND: Nosocomial infections (NIs) have a serious impact on patient outcomes in Intensive Care Units (ICUs).

    METHOD: A prospective cohort-targeted comprehensive surveillance study on NI associated with usage of devices was conducted in three ICUs in Malaysia using a developed NI surveillance form. Patients who developed infection outside an ICU were excluded from the study.

    RESULTS: The device associated NI was 21.1%. The mean duration for development of NI was 10.0 +/- 7.44 days in ICU. The major device-associated infections were nosocomial pneumonia (18.7%) followed by bacteremia (8.5%) and urinary tract infections (4.7%) respectively. NI incidence density rate was 20.6 per 1,000 patient-days. Bacteremia, urinary tract infection (UTI) and nosocomial pneumonia (NP) rates were 8.9, 4.7 and 20.5 per 1,000 patient-days, respectively. Acinetobacter species, Klebseilla pneumoniae, Pseudomonas aeruginosa and Methicillin-resistant Staphylococcus aureus were the predominant pathogens isolated from the NIs subjects during the study period in the three ICUs.

    CONCLUSION: Analysis of the rate of the NIs associated with usage of devices in the three ICUs showed that it is highly correlated with the use of mechanical ventilation devices, followed by intravascular devices and usage of indwelling urinary catheters.

    INTRODUCTION: Acinetobacter baumannii is a Gram-negative nosocomial pathogen that has the capacity to develop resistance to all classes of antimicrobial compounds. However, very little is known regarding its susceptibility to biocides (antiseptics and disinfectants) and capacity to form biofilms, particularly for Malaysian isolates.

    AIM: To determine the susceptibility of A. baumannii isolates to commonly-used biocides, investigate their biofilm-forming capacities and the prevalence of biocide resistance and biofilm-associated genes.

    METHODOLOGY: . The minimum inhibitory concentration (MIC) values of 100 A. baumannii hospital isolates from Terengganu, Malaysia, towards the biocides benzalkonium chloride (BZK), benzethonium chloride (BZT) and chlorhexidine digluconate (CLX), were determined by broth microdilution. The isolates were also examined for their ability to form biofilms in 96-well microplates. The prevalence of biocide resistance genes qacA, qacE and qacDE1 and the biofilm-associated genes bap and abaI were determined by polymerase chain reaction (PCR).

    RESULTS: Majority of the A. baumannii isolates (43%) showed higher MIC values (> 50 µg/mL) for CLX than for BZK (5% for MIC > 50 µg/mL) and BZT (9% for MIC > 50 µg/mL). The qacDE1 gene was predominant (63%) followed by qacE (28%) whereas no isolate was found harbouring qacA. All isolates were positive for the bap and abaI genes although the biofilm-forming capacity varied among the isolates.

    CONCLUSION: The Terengganu A. baumannii isolates showed higher prevalence of qacDE1 compared to qacE although no correlation was found with the biocides' MIC values. No correlation was also observed between the isolates' biofilm-forming capacity and the MIC values for the biocides.

    The novel coronavirus has become a global risk because of its massive transmission and high rates of mutation. Efficient clinical management remains a challenge in combatting the severe acute respiratory syndrome caused by this virulent strain. This contagious disease is new to the people of Bangladesh. The country is at high risk of spreading the coronavirus infection particularly because of its high population density. Significant morbidity and mortality have been observed for the quick transmission of this virus since March 8, 2020. The basic objective of this article is to analyze the preparedness of Bangladesh, given its constraints and limitations, to cope with the rapid spread of COVID-19 infection. In doing so, it summarizes the origin of coronavirus, epidemiology, mode of transmission, diagnosis, treatment, prevention and control of the disease. Although many steps have been taken by the Government and the private sector of Bangladesh to create awareness about measures needed to prevent the deadly infections, many people are unaware of and reluctant to accept the prescribed rules. Inadequacy of diagnostic facilities and limitations of clinical care and health care services were major constraints faced in treating COVID-19 infected people in Bangladesh. Greater compliance by the people in following the suggested measures may help reduce the rapid spread of the disease and overcome the challenges faced by this pandemic.

    INTRODUCTION: During the second wave of the coronavirus disease 19 (COVID-19) pandemic, Malaysia reported several COVID-19 clusters related to healthcare workers. Thus, addressing and understanding the risk of exposure in healthcare workers is important to prevent future infection and reduce secondary COVID-19 transmission within the healthcare settings. In this study, we aim to assess exposure and prevention practices against COVID-19 among healthcare workers at the Hospital Canselor Tuanku Muhriz, a university teaching hospital based in Kuala Lumpur, Malaysia.

    METHODOLOGY: A total of 571 healthcare workers at COVID-19 and non-COVID-19 wards as well as the emergency department and laboratory staff at COVID-19 testing labs were recruited. The presence of novel human coronavirus (SARS-CoV-2) and IgM/IgG antibodies were confirmed in all healthcare workers. The healthcare workers responded to an online Google Forms questionnaire that evaluates demographic information and comorbidities, exposure and adherence to infection prevention and control measures against COVID-19. Descriptive analysis was performed using Statistical Package for the Social Sciences 24.0.

    RESULTS: Three healthcare workers (0.5%) tested positive for SARS-CoV-2, while the remaining 568 (99.5%) were negative. All were negative for IgM and IgG antibodies during recruitment (day 1) and follow-up (day 15). More than 90% of the healthcare workers followed infection prevention and control practices recommendations regardless of whether they have been exposed to occupational risk for COVID-19.

    CONCLUSIONS: The healthcare workers' high level of adherence to infection prevention practices at this hospital helped reduce and minimize their occupational exposure to COVID-19.

    INTRODUCTION: Information on the clinical characteristics of local patients with confirmed COVID-19 is limited. This study aims to report the clinical characteristics of 147 patients admitted and receiving treatment at a teaching hospital.

    METHODOLOGY: Patients' socio-demographic and epidemiological data, clinical features, laboratory findings and clinical outcomes were extracted using a data sheet.

    RESULTS: The median patient age was 25 [interquartile range (IQR)] 20-44) years, and most of patients were male (68.7%) and of Malaysian nationality (88.4%). Almost half of the patients were from a case cluster related to a religious event (48.3%) and 12.9% had a history of overseas travel. A total of 33.3% of patients were not related to any case cluster, i.e. sporadic cases. Radiological investigation showed that 13.6% of the patients had chest X-ray changes and all laboratory parameters were within the normal ranges. Sixty-six patients (44.9%) experienced symptoms. The most common symptoms were rhinitis (66.7%), followed by fever (19.7%) and cough (15.2%). Age, gender, case cluster, comorbidity status, haemoglobin, albumin, total protein, bilirubin total and alkaline phosphatase level were associated with symptomatic status.

    CONCLUSIONS: In this single-centre study, COVID-19 infection led not only to case clusters, but also to sporadic infections, with patients being either symptomatic or asymptomatic. These sporadic cases and asymptomatic patients may hamper effective contact tracing, leading to rapid human-to-human transmission in our population. Future studies on the prevalence and clinical significance of asymptomatic and presymptomatic COVID-19 patients would pre-emptively address issues on further containment of the pandemic.

    BACKGROUND: Melioidosis is an important public health problem causing community acquired sepsis in the northeastern part of Malaysia.

    METHODOLOGY: From January 2001 to December 2005, we reviewed case reports of all bacteraemic melioidosis admitted to a tertiary teaching hospital, Hospital Universiti Sains Malaysia.

    RESULTS: Thirty-five patients had positive blood culture for meliodosis and 27 case reports were traceable for further analysis. The mean age was 46.8 + 20.0 years. Twenty patients (74.1%) were male. The main clinical presentation was fever that occurred in 23 (85.2%) patients. Eighteen patients (66.7%) had lung involvement and three patients had liver abscess. Two patients presented with scrotal swelling, one of whom further developed Fournier's Gangrene. Nineteen (70.4%) patients had underlying diabetes, five of whom were newly diagnosed during the admission. Thirteen (48.1%) patients were treated with high-dose ceftazidime and six (22.2%) patients were treated with imipenem. Eight (29.6%) patients were not given anti-melioidosis therapy because the causative agents were not identified until after the patients died. The patients were admitted 16.8 days + 18.1. Seventeen patients (63.0%) died in this series, 13 patients of whom died within four days of admission.

    CONCLUSIONS: The wide range of clinical presentations and the fatal outcomes of melioidosis require a high level of suspicion among physicians to develop an early appropriate therapy and reduce the mortality rate.

    INTRODUCTION: National strategies to control COVID-19 pandemic consisted mostly of social distancing measures such as lockdowns, curfews, and stay-home guidelines, personal protection such as hand hygiene and mask wearing, as well as contact tracing, isolation and quarantine. Whilst policy interventions were broadly similar across the globe, there were some differences in individual and community responses. This study explored community responses to COVID-19 containment measures in different countries and synthesized a model. This exaplains the community response to pandemic containment measures in the local context, so as to be suitably prepared for future interventions and research.

    METHODOLOGY: A mutlinational study was conducted from April-June 2020 involving researchers from 12 countries (Japan, Austria, U.S., Taiwan, India, Sudan, Indonesia, Malaysia, Philippines, Myanmar, Vietnam and Thailand). Steps in this research consisted of carrying out open-ended questionnaires, qualitative analyses in NVivo, and a multinational meeting to reflect, exchange, and validate results. Lastly, a commuinty response model was synthesized from multinational experiences.

    RESULTS: Effective communication is key in promoting collective action for preventing virus transmission. Health literacy, habits and social norms in different populations are core components of public health interventions. To enable people to stay home while sustaining livelihoods, economic and social support are essential. Countries could benefit from previous pandemic experience in their community response. Whilst contact tracing and isolation are crucial intervention components, issues of privacy and human rights need to be considered.

    CONCLUSIONS: Understanding community responses to containment policies will help in ending current and future pandemics in the world.

    INTRODUCTION: Malaysia is an upper-middle-income country with national antimicrobial stewardship programs in place. However, hospitals in this country are faced with a high incidence of multidrug-resistant organisms and high usage of broad-spectrum antibiotics. Therefore, this study aimed to use a standardized audit tool to assess clinical appropriateness, guideline compliance, and prescribing patterns of antimicrobial use among medical patients in two tertiary hospitals in Malaysia to benchmark practice.

    METHODOLOGY: A prospective hospital-wide point prevalence survey was carried out by a multidisciplinary team in April 2019 at the University Malaya Medical Centre (UMMC) and the Hospital Canselor Tuanku Muhriz (HCTM), Kuala Lumpur, Malaysia. Data was collected from the patient's electronic medical records and recorded using the Hospital National Antimicrobial Prescribing Survey toolkit developed by the National Centre for Antimicrobial Stewardship, Australia.

    RESULTS: The appropriateness of prescriptions was 60.1% (UMMC) and 67% (HCTM), with no significant difference between the two hospitals. Compliance with guidelines was 60.0% (UMMC) and 61.5% (HCTM). Amoxicillin-clavulanic acid was the most commonly prescribed antimicrobial (UMMC = 16.9%; HCTM = 11.9%).

    CONCLUSIONS: The appropriateness of antimicrobial prescribing in medical wards, compliance with guidelines, and prescribing patterns were similar between the two hospitals in Malaysia. The survey identified several areas of prescribing that would need targeted AMS interventions.

    BACKGROUND: Streptococcus pneumoniae is a major human pathogen. The emergence of penicillin resistant strains since the 1970s has been life threatening and the evolution of the bacteria have enabled itself to develop resistance to many other antibiotics such as the macrolides and the fluoroquinolones. This study aims to characterize S. pneumoniae isolates for the presence of penicillin and macrolide resistance genes.

    METHODOLOGY: One hundred and twenty clinical isolates of S. pneumoniae were obtained from patients of University Malaya Medical Centre (UMMC). The strains were screened using a multiplex real-time PCR method for the presence of alterations in the genes encoding the penicillin binding proteins: pbp2b, macrolide resistance determinant ermB and the pneumolysin gene, ply. Dual-labelled Taqman probes were used in the real-time detection method comprising three different genes labeled with individual fluorophores at different wavelengths. One hundred and twenty isolates from bacterial cultures and isolates directly from blood cultures samples were analyzed using this assay.

    RESULTS: A multiplex PCR comprising the antibiotic resistance genes, ermB and and pneumolysin gene (ply), a S. pneumoniae species specific gene, was developed to characterize strains of S. pneumoniae. Out of the 120 pneumococcal isolates, 58 strains were categorized as Penicillin Sensitive Streptococcus pneumoniae (PSSP), 36 as Penicillin Intermediate Streptococcus pneumoniae (PISP) and 26 as Penicillin Resistant Streptococcus pneumoniae (PRSP). All the 58 PSSP strains harboured the pbp2b gene while the 36 PISP and 26 PRSP strains did not harbour this gene, thus suggesting reduced susceptibility to penicillin. Resistance to erythromycin was observed in 47 of the pneumococcal strains while 15 and 58 were intermediate and sensitive to this drug respectively. Susceptibility testing to other beta-lactams (CTX and CRO) also showed reduced susceptibility among the strains within the PISP and PRSP groups but most PSSP strains were sensitive to other antibiotics.

    CONCLUSION: The characterization of pneumococcal isolates for penicillin and erythromycin resistance genes could be useful to predict the susceptibility of these isolates to other antibiotics, especially beta-lactams drugs. We have developed an assay with a shorter turnaround time to determine the species and resistance profile of Streptococcus pneumoniae with respect to penicillin and macrolides using the Real Time PCR format with fluorescent labeled Taqman probes, hence facilitating earlier and more definitive antimicrobial therapy which may lead to better patient management.

    Tuberculosis is notoriously known to be a great mimicker of other diseases and may cause various haematologic abnormalities, especially with marrow involvement. A 61-year-old man who presented with right empyema and pancytopenia was diagnosed to have disseminated tuberculosis supported by the presence of caseating granuloma with Langhan's giant cells in the marrow and demonstration of acid-fast bacilli in the pleural fluid. Trilineage dysplasia from marrow aspirate was initially attributed to be reactive to the infection. A cytogenetic study was repeated after he showed poor response to a year of anti-tuberculosis treatment. The underlying primary myelodysplastic syndrome was unmasked when his cytogenetics showed trisomy 8. This case report has demonstrated the various haematological manifestations of tuberculosis and highlighted the importance of cytogenetic study in differentiating between primary and secondary myelodysplastic marrow changes.
