    BACKGROUND AND PURPOSE: Training pharmacy students in infectious diseases (ID) is important to enable them to participate in antibiotic stewardship programs. This study evaluated knowledge and self-confidence regarding antibiotic resistance, appropriate antibiotic therapy, and antibiotic stewardship among final year pharmacy undergraduate students.

    METHODS: A cross-sectional electronic survey was conducted at universities in Indonesia, Malaysia, and Pakistan. A 59-item survey was administered between October 2017 and December 2017.

    FINDINGS: The survey was completed by 211 students (response rate 77.8%). The mean knowledge score for antibiotic resistance, appropriate antibiotic therapy, and antibiotic stewardship was 5.6 ± 1.5, 4.7 ± 1.8 (maximum scores 10.0) and 3.1 ± 1.4 (maximum score 5.0), respectively. Significant variations were noted among the schools. There was poor awareness about the consequences of antibiotic resistance and cases with no need for an antibiotic. The knowledge of antibiotic resistance was higher among male respondents (6.1 vs. 5.4) and those who had attended antibiotic resistance (5.7 vs. 5.2) and antibiotic therapy (5.8 vs. 4.9) courses (p

    We report for the first time on the prevalence, antibiotic resistance and RAPD types of Campylobacter species in ducks and duck related environmental samples in Malaysia. Samples were examined by enrichment in Bolton Broth followed by plating onto modified Charcoal Cefoperazone Deoxycholate agar (mCCDA) and/or plating directly onto mCCDA. A total of 643 samples were screened, and the prevalence of Campylobacter spp. in samples from different sources ranged from 0% to 85%. The method of isolation had a significant (P<0.05) effect on the isolation rate. One hundred and sixteen Campylobacter isolates, comprising of 94 Campylobacter jejuni, 19 Campylobacter coli and three Campylobacter lari, were examined for their sensitivity to 13 antibiotics. Majority of the C. jejuni isolates were resistant to cephalothin (99%), tetracycline (96%), suphamethoxazole/trimethoprim (96%), and very few were resistant to gentamicin (5%), chloramphenicol (7%) and erythromycin (1%). All C. coli isolates were resistant to cephalothin, nalidixic acid, norfloxacin and tetracycline but susceptible to chloramphenicol, erythromycin and gentamicin. The three C. lari isolates were resistant to all the antibiotics tested except chloramphenicol and gentamicin (1/3 and 2/3 susceptible, respectively). Genetic diversity of Campylobacter isolates were determined using random amplification of polymorphic DNA (RAPD). C. jejuni and C. coli isolates belong to fifty-eight and twelve RAPD types, respectively.

    BACKGROUND: There is limited research on pharmacy specialization based differences with regards to usage of antibiotics.

    OBJECTIVE: To compare the knowledge, attitude and practice of Bachelor of Pharmacy (BPharm) and Doctor of Pharmacy (PharmD) students about usage and resistance of antibiotics in Southern India.

    METHODS: This was a cross sectional study involving final year BPharm and PharmD students studying in two private institutions located in Andra Pradesh, India. The study was conducted for the period of 3 months. The questionnaire was divided into 5 components: demographics, knowledge about antibiotic use, attitude towards antibiotic use and resistance, self-antibiotic usage, and possible causes of antibiotic resistance. The study questionnaire was assessed for reliability. Data were analysed by employing Mann Whitney and chi square tests using SPSS version 19.

    RESULTS: The sample size comprised of 137 students. The response rate was 76.11% for the study. There was a significant difference in the knowledge of antibiotic use in BPharm and PharmD students (Mean score: 5.09 vs 6.18, p<0.001). The overall attitude of PharmD students about antibiotic use and resistance was positive compared to BPharm students (Mean score: 3.05 vs 2.23, p<0.05). The self-antibiotic practices was higher in BPharm students than PharmD students (36.4% vs 20%, p<0.05). A significantly high number of PharmD students believed that empirical antibiotic therapy led to antibiotic resistance (19.5% versus 48%, P<0.05).

    CONCLUSION: PharmD students were more knowledgeable about antibiotic usage and resistance compared to BPharm students who did not have accurate and the much needed information about the same. Future interventions should be targeted towards educating the BPharm students so that they can implement the acquired knowledge in their practice.

    Antimicrobial resistance (AMR) is a ubiquitous public health menace. AMR emergence causes complications in treating infections contributing to an upsurge in the mortality rate. The epidemic of AMR in sync with a high utilization rate of antimicrobial drugs signifies an alarming situation for the fleet recovery of both animals and humans. The emergence of resistant species calls for new treatments and therapeutics. Current records propose that health drug dependency, veterinary medicine, agricultural application, and vaccination reluctance are the primary etymology of AMR gene emergence and spread. Recently, several encouraging avenues have been presented to contest resistance, such as antivirulent therapy, passive immunization, antimicrobial peptides, vaccines, phage therapy, and botanical and liposomal nanoparticles. Most of these therapies are used as cutting-edge methodologies to downplay antibacterial drugs to subdue the resistance pressure, which is a featured motive of discussion in this review article. AMR can fade away through the potential use of current cutting-edge therapeutics, advancement in antimicrobial susceptibility testing, new diagnostic testing, prompt clinical response, and probing of new pharmacodynamic properties of antimicrobials. It also needs to promote future research on contemporary methods to maintain host homeostasis after infections caused by AMR. Referable to the microbial ability to break resistance, there is a great ultimatum for using not only appropriate and advanced antimicrobial drugs but also other neoteric diverse cutting-edge therapeutics.

    Objective: This study aimed to understand the dispensing practice of antibiotics in community pharmacy in Iraq, in addition to explore the community pharmacists' perception about dispensing antibiotics without prescription.

    Methods: A qualitative design was conducted on community pharmacists in Baghdad, Iraq. Pharmacists were selected conveniently from different gender, age group, pharmacy type and years of experience. Face-to-face semi-structure interview was used with all the pharmacists to get in-depth understanding about their dispensing practice of antibiotics without prescription in community pharmacy. The data was coded and classified for thematic analysis.

    Results: This study found that dispensing of antibiotics without prescription was a common practice in community pharmacy. Pharmacists' perception towards dispensing antibiotics without prescription was associated with the medical condition, safety and efficacy of antibiotics, patients request antibiotics by name, emergency cases, regular customer, promotions from pharmaceutical companies, saving time and cost, brand medications, and poor healthcare services. In addition, there were inadequate knowledge about antibiotic resistance and lack of awareness about antibiotic stewardship leading to inappropriate dispensing practice.

    Conclusions: Community pharmacists have poor perception towards dispensing antibiotics without prescription. Educational interventions about antibiotics use focusing on community pharmacists are needed. This will help to optimize the practice of dispensing of antibiotics in the community. In addition, training programs about antibiotic resistance are important to enhance pharmacists' understanding about antibiotic stewardship.

    Increasing risk of antibiotic resistance of pathogenic bacteria has led to the exploration of alternative antibiotics derived from leaves of medicinal plants such as the fig (Ficus carica L.). The aim of this study was to determine the antimicrobial activity of the methanolic extract of fig leaves grown under Malaysian tropical environment against pathogenic bacteria linked to antibiotic resistance namely the Staphylococcus aureus and Escherechia coli. The methanolic extraction was performed by using soxhlet apparatus. The disc diffusion method was used to measure inhibition zone diameter on the Mueller-Hinton agar plate. Staphylococcus aureus displayed the highest diameter of inhibition zone against the extract at concentration of 900 mg/ml whilst Escherechia coli displayed the highest diameter of inhibition zone against both the 100% crude extract and 700 mg/ml, respectively. This study therefore highlighted the potential of developing alternative antibiotics derived from the methalonic extract of locally grown fig plant.

    Six Campylobacter jejuni clinical isolates were examined for the occurrence of plasmids in association with antibiotic resistances as well as conjugal transfer. All the isolates were found to carry three similar plasmids of 78 kb, 12.6 kb and 3.3 kb in size. Multiple resistance to at least three of the antibiotics tested was observed with resistance to tetracycline most common. En bloc transfer of donor resistances at frequencies ranging from 10(-8) to 10(-4) were seen in all but one of the isolates during conjugation. The conjugal transfer of erythromycin, neomycin and streptomycin were observed to occur at frequencies similar to that of chloramphenicol, kanamycin and tetracycline. In isolate ABA94, three different antibiotic resistance phenotypes of the transconjugants were seen. In addition to en bloc transfer of the donor resistances, in approximately 10% of the transconjugants the streptomycin resistance was lost although these transconjugants carried the donor complement of three plasmids. In a further 1% of the transconjugants, resistance to kanamycin only was detected and these transconjugants did not carry any plasmids.

    Clinical resistance to penicillin in Streptococcus pneumoniae was first reported by researchers in Boston in 1965; subsequently, this phenomenon was reported from Australia (1967) and South Africa (1977). Since these early reports, penicillin resistance has been encountered with increasing frequency in strains of S. pneumoniae from around the world. In South Africa strains resistant to penicillin and chloramphenicol as well as multiresistant strains have been isolated. Similar patterns of resistance have been reported from Spain. Preliminary evidence points to a high prevalence of resistant pneumococci in Hungary, other countries of Eastern Europe, and some countries in other areas of Europe, notably France. In the United States most reports of resistant pneumococci come from Alaska and the South, but resistance is increasing in other states and in Canada. Pneumococcal resistance has also been described in Zambia, Japan, Malaysia, Pakistan, Bangladesh, Chile, and Brazil; information from other African, Asian, and South American countries is not available. The rising prevalence of penicillin-resistant pneumococci worldwide mandates selective susceptibility testing and epidemiological investigations during outbreaks.

    OBJECTIVES: To evaluate prevalence of ceftazidime-resistant Klebsiella pneumoniae (CRKP) in the pediatric oncology unit of University Hospital, Kuala, Lumpur, and to identify differences between febrile neutropenic pediatric patients with CRKP and ceftazidime-sensitive K. pneumoniae (CSKP) bacteremia.

    MATERIALS AND METHODS: Febrile neutropenic patients treated between January 1996 and December 1997 at the pediatric oncology unit of University Hospital, Kuala Lumpur, were prospectively studied. Empirical antibiotic therapy consisted of ceftazidime and amikacin. Those who developed K. pneumoniae bacteremia were identified, and clinical features analyzed. Ceftazidime-resistance was documented via disk-diffusion testing. Production of extended-spectrum beta-lactamase (ESBL) was inferred on the basis of synergy between ceftazidime and amoxicillin-clavulanic acid. The different features between the two groups and variables associated with the development of CRKP bacteremia were analyzed using chi-square and t-tests and calculation of odds ratios. A multivariate analysis was used to identify independent factors for CRKP development.

    RESULTS: Ceftazidime-resistance was seen in 51.6% of all K. pneumoniae isolates, and all these isolates were inferred to be ESBL producers. All isolates were sensitive to imipenem. Susceptibility to gentamicin was 90.5%. The mean continuous hospital stay prior to the detection of bacteremia was 13.7 days overall, but significantly longer in the CRKP group (21.9 d) compared to the CSKP group (4.3 d) (P = 0.003). Children with CRKP were more likely to have received antibiotics in the 2 weeks prior to detection of bacteremia (87.5% of cases) than the CSKP group (20.0% of cases) (P = 0.0008). Sepsis-related mortality was higher in those with CRKP (50.0%) than in the CSKP group (13.3%) (P = 0.02). Patients who did not receive CRKP-directed antibiotics within 48 hours of admission were more likely to have a fatal outcome than those who did (P = 0.009). Logistic regression analysis identified use of third-generation cephalosporins 2 weeks prior to presentation and a hospital stay of 2 weeks or more as independent risk factors for development of CRKP.

    CONCLUSIONS: More than half of total K. pneumoniae isolated from blood cultures in the unit were ceftazidime-resistant. Children with febrile neutropenia with prolonged hospital stay and recent prior antibiotic exposure are at high risk of developing CRKP bacteremia. Mortality was significantly higher in this group. Early commencement of appropriate antibiotics (e.g., imipenem with or without gentamicin), according to susceptibility study results, may be beneficial in such circumstances.

    The issue of antibiotic resistance has been around ever since the first antibiotic penicillin was introduced to the world. It continues to rise, becoming a major problem across the globe and Malaysia is no exception. Hospital is a critical component of the antibiotic resistance problem worldwide. The problems of antibiotic resistance are typically magnified in a hospital setting due to the common variables in the hospital environment that favour its development. These include a combination of highly susceptible patients, intensive and prolonged antibiotic use, and crossinfection resulting in nosocomial infections with highly resistant bacterial pathogens such as multi-resistant gram-negative rods, vancomycin resistant enterococci (VRE) and methicillinresistant Staphylococcus aureus (MRSA) as well as resistant fungal infections. Transmission of highly resistant bacteria from patient to patient within the hospital environment amplifies the problem of antibiotic resistance and may result in the infection of patients who are not receiving antibiotics. Transmission of antibiotic-resistant strains from hospital personnel to patients or vice versa may also occur. What are the available strategies and what works best in managing antibiotic resistance in the hospital? This review will highlight the seriousness of the resistance problem and identify actions that address it especially in the context of improving the problem in Malaysian hospitals.

    This study was carried out to know the bacteria population density in the blood cockle (Anadara granosa) and green lipped mussel (Perna viridis), to analyse the bacteria resistance towards antibiotics and antimicrobial activity of isolates against selected pathogen. Samples of blood cockle and green lipped mussel were obtained from five areas in Kedah and Negeri Sembilan. Bacterial population densities in mussels and cockles were 3 x 102 - 8 x 108 cFulmL and 5 x 102 - 5 x 108 cFulmL, respectively. A total of 162 isolates were obtained, of which 131 isolates were from mussels and 31 isolates were from cockles. Vibrio sp. was the most dominant genus in both types of samples. Antibiotic testing of all isolates showed most were resistant to Penicillin (10 U) and most were sensitive to Ciprofloxacin (5 Jig). Most isolates (160/162) showed resistance to at least two antibiotics and 10 isolates were resistant to more than five antibiotics. Multiple antibiotic resistance indices (MAR) were calculated based on the antibiotic resistance results. Most isolates had a MAR index value of 02 which indicated the isolates were not contaminated with antibiotic residues. The highest index value was 0 .7 . Fifteen out of 39 isolates which produced beta-lactamase enzyme were tested for antimicrobial activity against selected pathogen. Results indicated that antimicrobial activity were varies among the isolates. Isolate smii-Ip produced antimicrobial activity against six out of the nine tested pathogen and none of the isolates active against Pseudomonas mirabilis.

    Cefotaxime [HR 756], a third generation cephalosporin with pronounced antibacterial activity
    against the Enterobacteriaceae, was assessed in serious and problem antibiotic resistant infection. Good clinical success was achieved without observed untoward effects. The study suggests that due to its properties, cefotaxime could be used as a first-line antibiotic provided that the clinical situation warrants the use of a cephalosporin or aminoglycoside.
    Key words - cefotaxime [HR 756], serious surgical infection, antibiotic resistant infection.

    Salmonella and Vibrio species were isolated and identified from Litopenaeus vannamei cultured in shrimp farms. Shrimp samples showed occurrence of 3.3% of Salmonella and 48.3% of Vibrio. The isolates were also screened for antibiotic resistance to oxolinic acid, sulphonamides, tetracycline, sulfamethoxazole/trimethoprim, norfloxacin, ampicillin, doxycycline hydrochloride, erythromycin, chloramphenicol, and nitrofurantoin. Salmonella enterica serovar Corvallis isolated from shrimp showed individual and multiple antibiotic resistance patterns. Five Vibrio species having individual and multiple antibiotic resistance were also identified. They were Vibrio cholerae (18.3%), V. mimicus (16.7%), V. parahaemolyticus (10%), V. vulnificus (6.7%), and V. alginolyticus (1.7%). Farm owners should be concerned about the presence of these pathogenic bacteria which also contributes to human health risk and should adopt best management practices for responsible aquaculture to ensure the quality of shrimp.

    A case of Plasmodium falciparum malaria resistant to Fansidar (sulphadoxine plus pyrimethamine) at a level corresponding to R III and resistant to chloroquine is reported. The infection was most certainly acquired in Malaysia, but diagnosed and treated in a non-malarious area. Normal resorption and elimination rates of the Fansidar components excludes cure failure due to abnormal drug fate in the host. P. falciparum parasites from the patient have been maintained in vitro cultures. The patient was permanently cured with mefloquine.

    Acute pharyngitis (AP) is a common reason for private primary care consultations, thus providing an avenue for widespread antibiotic intake among the community. However, there is limited data on the antibiotic prescription appropriateness and resistance information in the Malaysian private primary care setting, therefore, this study aimed to investigate the prevalence of isolated viruses and bacteria, antibiotic resistance patterns, antibiotic prescription patterns and appropriateness by general practitioners (GPs) and factors affecting antibiotic resistance and antibiotic prescription patterns. To investigate, a cross-sectional study was conducted among 205 patients presenting with AP symptoms at private primary care clinics in central Malaysia from 3rd January 2016 to 30th November 2016. Throat swabs were collected from 205 AP patients for two purposes: (i) the detection of four common respiratory viruses associated with AP via reverse-transcription real-time PCR (qRT-PCR); and (ii) bacterial identification using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS). Bacterial isolates were then subjected to antibiotic susceptibility screening and McIsaac scoring was calculated post-prescription based on GP selection of criteria. Generalized estimating equations analysis with multiple logistic regression was conducted to identify factors associated with presence of virus and antibiotic prescription. The results showed that 95.1% (195/205) of patients had at least one of the four viruses, with rhinovirus (88.5%) being the most prevalent, followed by adenovirus (74.9%), influenza A virus (4.6%) and enterovirus (2.1%). A total of 862 non-repetitive colonies were isolated from the culture of throat swabs from 205 patients who were positive for bacteria. From a total of 22 genera, Streptococcus constitutes the most prevalent bacteria genus (40.9%), followed by Neisseria (20%), Rothia (13.0%), Staphylococcus (11%) and Klebsiella (4.9%). Only 5 patients carried group A beta-hemolytic streptococci (GABHS). We also report the presence of vancomycin-resistant S. aureus or VRSA (n = 9, 10.1%) among which one isolate is a multidrug-resistant methicillin-resistant S. aureus (MDR-MRSA), while 54.1% (n = 111) were found to carry at least one antibiotic-resistant bacteria species. Application of the McIsaac scoring system indicated that 87.8% (n = 180) of patients should not be prescribed antibiotics as the majority of AP patients in this study had viral pharyngitis. The antibiotic prescription appropriateness by applying post-prescription McIsaac scoring was able to rule out GABHS pharyngitis in this sample with a GABHS culture-positive sensitivity of 40% (n = 2/5) and specificity of 90% (180/200). In conclusion, antibiotic-resistant throat isolates and over-prescription of antibiotics were observed and McIsaac scoring system is effective in guiding GPs to determine occurrences of viral pharyngitis to reduce unnecessary antibiotic prescription.
