Han HS, Toh PY, Yoong HB, Loh HM, Tan LL, Ng YY

Vet Dermatol, 2018 Oct;29(5):442-e148.
PMID: 30066413 DOI: 10.1111/vde.12672

BACKGROUND: Cutaneous screw-worm myiasis in companion animals either due to the New World screw-worm, Cochliomyia hominivorax or the Old World screw-worm, Chrysomya bezziana, has been reported particularly in tropical and subtropical regions of the world. Although treatment of screw-worm myiasis in dogs has been described, few studies have been conducted regarding its clinical and epidemiological aspects in companion animals.
OBJECTIVES: To describe clinical and epidemiological aspects of canine and feline screw-worm myiasis.
ANIMALS: Naturally infested dogs and cats, presented to five veterinary clinics in four Malaysian states from September 2017 to February 2018.
METHODS AND MATERIALS: Cutaneous screw-worm myiasis was diagnosed based on clinical signs and visual examination of burrowing larvae within lesion. Age, breed, gender, anatomical site of infestation and suspected underlying predisposing causes were investigated.
RESULTS: A total of 55 dogs and 21 cats were included in the study. Intact male mixed breed dogs (mean age 58 months) and intact male domestic short hair cats (mean age 24 months) with suspected fight-related wounds were most commonly presented with exudative and ulcerative lesions associated with screw-worm myiasis. The most common anatomical sites of infestation in the dogs were the external ear canals, followed by the perineum and medial canthus. For the cats, the most commonly affected areas were paws and tail. Five cats with screw-worm myiasis were concurrently infected with sporotrichosis.
CONCLUSION AND CLINICAL RELEVANCE: Aggression between unneutered animals is a likely underlying cause for cutaneous screw-worm myiasis in both cats and dogs. Sporotrichosis was also a potential predisposing cause for screw-worm myiasis in cats.

Dissemination of vector-borne viruses, such as Zika virus (ZIKV), in tropical and sub-tropical regions has a complicated impact on the immunopathogenesis of other endemic viruses such as dengue virus (DENV), chikungunya virus (CHIKV) and human immunodeficiency virus (HIV). The consequences of the possible co-infections with these viruses have specifically shown significant impact on the treatment and vaccination strategies. ZIKV is a mosquito-borne flavivirus from African and Asian lineages that causes neurological complications in infected humans. Many of DENV and CHIKV endemic regions have been experiencing outbreaks of ZIKV infection. Intriguingly, the mosquitoes, Aedes Aegypti and Aedes Albopictus, can simultaneously transmit all the combinations of ZIKV, DENV, and CHIKV to the humans. The co-circulation of these viruses leads to a complicated immune response due to the pre-existence or co-existence of ZIKV infection with DENV and CHIKV infections. The non-vector transmission of ZIKV, especially, via sexual intercourse and placenta represents an additional burden that may hander the treatment strategies of other sexually transmitted diseases such as HIV. Collectively, ZIKV co-circulation and co-infection with other viruses have inevitable impact on the host immune response, diagnosis techniques, and vaccine development strategies for the control of these co-infections.

Nosocomial blood stream infection (or nosocomial bacteremia) is a common problem in hospitals worldwide, including Malaysia. A three-year prospective cohort study (October 2003-March 2007) of the incidences, risk factors, and patterns of the microorganisms causing bacteremia was conducted using a validated surveillance form in three intensive care units (ICUs) in Malaysia. Center for Disease Control criteria were used to diagnose bacteremia. Patients were monitored from admission until the end point of study, which was the first detection of bacteremia in the blood in each patient. The frequency of occurrence of bacteremia with clinical symptoms was 10.7% (n=23). Bacteremia was observed to occur within a mean length of stay of 10 days in ICU. The rate of device-related infection was 10.4% per device utilization days with a device utilization rate of 95.9%/1000 patient days. The total number of patient days was 2309 and the period of device utilization was 2211 days. The common bacteria detected were extended-spectrum beta-lactamases (ESBLs) Klebsiella pneumoniae (n=6); Pseudomonas aeruginosa (n=6); Acinetobacter species (n=5); Methicillin-resistant Staphylococcus aureus (MRSA)(n=3); and (non- ESBL) Klebsiella pneumoniae (n=2). Multivariable analysis using Cox Proportional Hazard Model showed that the predictors for developing bacteremia were cancer, MRSA carriage, duration of central venous catheter (CVC) infusion, frequency change of CVC, and the administration of hydrocortisone drugs. These results indicate that a combination of nursing and medical interventions as well as patients' severity of illness could lead to bacteremia in ICU. Strategic implementation of quality assurance measures in ICUs could help to control this problem.

Abubakar U, Syed Sulaiman SA, Adesiyun AG

Int J Clin Pharm, 2018 Oct;40(5):1037-1043.
PMID: 30054786 DOI: 10.1007/s11096-018-0702-0

Background Audit of antibiotic prophylaxis is an important strategy used to identify areas where stewardship interventions are required. Objectives To evaluate compliance with surgical antibiotic prophylaxis in obstetrics and gynaecology surgeries and determine the Defined Daily Dose (DDD) of antibiotic. Settings Three public tertiary hospitals located in Northern Nigeria. Methods This prospective study included women who had obstetrics and gynaecology surgeries with no infection at the time of incision. Appropriateness of antibiotic prophylaxis was determined by a clinical pharmacist. DDD of antibiotics was determined using ATC/DDD index 2017 from the World Health Organization Collaborating Centre for Drugs Statistics Methodology. Main outcome measure Compliance with antibiotic prophylaxis and DDD of antibiotic per procedure. Results A total of 248 procedures were included (mean age: 31.7 ± 7.9 years). Nitroimidazole in combination with either beta-lactam/beta-lactamase inhibitor or third generation cephalosporin were the most prescribed antibiotics. Redundant anaerobic antibiotic combination was detected in 71.4% of the procedures. Timing of antibiotic prophylaxis was optimal in 16.5% while duration of prophylaxis was prolonged in all the procedures (mean duration was 8.7 ± 1.0 days). The DDD of antibiotics prophylaxis was 16.75 DDD/procedure. Antibiotic utilisation was higher in caesarean section and myomectomy (17.9 DDD/procedure) than hysterectomy (14.5 DDD/procedure); P

Misbah S, AbuBakar S, Hassan H, Hanifah YA, Yusof MY

J Hosp Infect, 2004 Dec;58(4):254-61.
PMID: 15564001

The antibiotic susceptibility profiles and the repetitive extragenic palindromic sequence-based polymerase chain reaction (REP-PCR)-determined genotypes of 109 Acinetobacter strains collected from the University Malaya Medical Center (UMMC), Kuala Lumpur, Malaysia, in 1987 (N=21) and 1996-1998 (N=88) were established. Twelve antibiotic susceptibility profiles of antibiotics used at the UMMC were obtained. In descending order of effectiveness, imipenem, amikacin and ciprofloxacin were the most effective against the Acinetobacter strains. Compared with 1987 isolates, the isolates obtained in 1996-1998 had decreased susceptibility to these antibiotics and were tolerant to the antibiotics up to an MIC90 of > or =256 mg/L. REP-PCR DNA fingerprints of all the isolates revealed the presence of four Acinetobacter spp. lineages; 92% of all the isolates belonged to two dominant lineages (genotypes 1 and 4). Genotype 4 isolates predominant in 1987 showed increased resistance and antibiotic tolerance to imipenem, amikacin and ciprofloxacin compared with the 1996-1998 isolates. In contrast, genotype 1 isolates from 1996-1998 were mainly sensitive to these antibiotics. These findings demonstrate the presence of at least two independent Acinetobacter spp. lineages in the same hospital, and suggest the possibility that genotype 4 Acinetobacter spp. acquired the resistance phenotype in situ, whereas most of the genotype 1 isolates were probably introduced to the hospital in recent years.

Ganeswire R, Thong KL, Puthucheary SD

J Hosp Infect, 2003 Apr;53(4):292-6.
PMID: 12660126

A nosocomial outbreak of bacteraemia, caused by Enterobacter gergoviae infected 11 babies, nine of whom were premature, and was investigated in the neonatal intensive care unit (NICU) of a general hospital in Johor Bahru, Malaysia. The strain that was isolated from the babies was also isolated from the dextrose saline used for the dilution of parenteral antibiotics and from the hands of a healthcare worker on duty in the nursery. Pulsed-field gel electrophoresis (PFGE) of Xba I-digested chromosomal DNA confirmed a possible cross-contamination of parenteral dextrose saline and the healthcare worker. Prompt and effective control measures were initiated within NICU and the nosocomial infection of E. gergoviae was brought to an abrupt end. To the best of our knowledge, this is the first documented outbreak of E. gergoviae in the NICU in a hospital in the state of Johor, Malaysia.

Al-Gethamy MM, Faidah HS, Adetunji HA, Haseeb A, Ashgar SS, Mohanned TK, et al.

J Int Med Res, 2017 Jun;45(3):1181-1189.
PMID: 28480813 DOI: 10.1177/0300060517706284

Objective To determine risk factors for multi-drug-resistant Acinetobacter baumannii (MDR-AB) nosocomial infections in intensive care units in a tertiary care hospital, Makkah, Saudi Arabia. Methods We performed a hospital-based, matched case-control study in patients who were admitted to Al Noor Specialist Hospital between 1 January 2012 and 31 August 2012. The study included cases of A. baumannii nosocomial infection and controls without infection. Controls were matched to cases by age and ward of admission. Results The most frequent site of infection was the respiratory tract (77.3%). Susceptibility to antimicrobial MDR-AB was 92.0% for ceftazidime and ciprofloxacin, while it was 83.3% for imipenem, 83.0% for trimethoprim, 79.0% for amikacin, and 72.7% for gentamicin. Multiple logistic regression of risk factors showed that immunosuppression (OR = 2.9; 95% CI 1.5-5.6; p = 0.002), clinical outcome (OR = 0.4; 95% CI 0.3-0.9; p = 0.01), invasive procedures (OR = 7.9; 95% CI 1.8-34.2; p = 0.002), a central venous catheter (OR = 2.9; 95% CI 1.5-5.6; p = 0.000), and an endotracheal tube (OR = 3.4; 95% CI 1.6-7.3; p = 0.001) were associated with MDR-AB. Conclusions Acinetobacter nosocomial infections are associated with admission to the ICU (Intensive care unit) and exposure to invasive procedures.

PMID: 26150452 DOI: 10.1128/AEM.01741-15

Enterococci rank as one of the leading causes of nosocomial infections, such as urinary tract infections, surgical wound infections, and endocarditis, in humans. These infections can be hard to treat because of the rising incidence of antibiotic resistance. Enterococci inhabiting nonhuman reservoirs appear to play a critical role in the acquisition and dissemination of antibiotic resistance determinants. The spread of antibiotic resistance has become a major concern in both human and veterinary medicine, especially in Southeast Asia, where many developing countries have poor legislation and regulations to control the supply and excessive use of antimicrobials. This review addresses the occurrence of antibiotic-resistant enterococci in Association of Southeast Asian Nations countries and proposes infection control measures that should be applied to limit the spread of multiple-drug-resistant enterococci.

PMID: 22666934

Methicillin-resistant Staphylococcus aureus (MRSA) emerged as a nosocomial pathogen in early 1960s, causing Increasing number of outbreaks in 19708, first reported in a teaching hospital in Malaysia in 1972, causing increased mortality, morbidity, and healthcare costs. Aim of this study is to screen out MRSA from various clinical samples and to see their antibiotic susceptibility pattern. From May 2008 to May 2009, 204 S aureus strains were isolated, out of which 114 (55.8%) were MRSA, and rest methicillin-sensitive Staphylococcus aureus (MSSA). Most of the MRSA strains were obtained from pus (45%) followed by urine (20.5%). Frequency of isolating MRSA were maximum in catheter tip (80%) followed by blood (66.7%) and pus (58.7%). MRSA strains were showing 100% sensitivity to vancomycin and Iinezolid, whereas 92.9% to teicoplanin. Therefore it is concluded that antibiotics other than vancomycin can be used as anti-MRSA agents after sensitivity test, as well as irrational and indiscriminate use of antibiotics can be avoided.

Rafiza S, Rampal KG

Int J Tuberc Lung Dis, 2012 Feb;16(2):163-8.
PMID: 22236915 DOI: 10.5588/ijtld.11.0364

BACKGROUND: Serial testing for tuberculosis (TB) exposure has been advocated among health care workers (HCWs) at risk of nosocomial infection.
OBJECTIVE: To determine the incidence and factors associated with TB infection among selected HCWs in Malaysia and to determine interferon-gamma response in serial testing.
DESIGN: A cohort of 769 HCWs were retested after 1 year using QuantiFERON®-TB Gold In-Tube. Incidence of TB infection was determined among HCWs who previously tested negative. Conversion and reversion rates using several definitions were explored.
RESULTS: Incidence of TB infection was 9.9 per 100 workers per year (95%CI 7.9-12.3). Working in the Emergency Department (ED; RR 2.18, 95%CI 1.07-4.43) was significantly associated with risk of TB infection. Reversion and conversion occurred frequently, with 46.7% reversion among HCWs with baseline interferon-gamma (IFN-γ) levels of 0.35-0.70 international units (IU)/ml, and 23.8% conversion among HCWs with baseline IFN-γ levels of 0.20-0.34 IU/ml.
CONCLUSIONS: TB infection control measures need to be strengthened, particularly in the ED, as the incidence of TB was high. Conversion and reversion rates in serial testing were high, and further studies are needed to facilitate its interpretation.

Dhanoa A, Ajit Singh V, Elbahri H

Surg Infect (Larchmt), 2015 Jun;16(3):323-32.
PMID: 26046246 DOI: 10.1089/sur.2014.049

Numerous studies have described various complications after endoprosthetic reconstructive operations. However, there are limited reports that focus specifically on deep infections (e.g., deep incisional surgical site infections), which remain one of the most dreaded complications of these operations, with rates ranging from 10% to 17%. Thus, this study was undertaken to determine the deep infection rates and to analyze possible risk factors, clinico-pathologic characteristics, and treatment modalities of endoprosthetic infections.

Fulltext Molecular Analysis of Antibiotic Resistance Determinants and Plasmids in Malaysian Isolates of Multidrug Resistant Klebsiella pneumoniae

Al-Marzooq F, Mohd Yusof MY, Tay ST

PLoS One, 2015;10(7):e0133654.
PMID: 26203651 DOI: 10.1371/journal.pone.0133654

Infections caused by multidrug resistant Klebsiella pneumoniae have been increasingly reported in many parts of the world. A total of 93 Malaysian multidrug resistant K. pneumoniae isolated from patients attending to University of Malaya Medical Center, Kuala Lumpur, Malaysia from 2010-2012 were investigated for antibiotic resistance determinants including extended-spectrum beta-lactamases (ESBLs), aminoglycoside and trimethoprim/sulfamethoxazole resistance genes and plasmid replicons. CTX-M-15 (91.3%) was the predominant ESBL gene detected in this study. aacC2 gene (67.7%) was the most common gene detected in aminoglycoside-resistant isolates. Trimethoprim/sulfamethoxazole resistance (90.3%) was attributed to the presence of sul1 (53.8%) and dfrA (59.1%) genes in the isolates. Multiple plasmid replicons (1-4) were detected in 95.7% of the isolates. FIIK was the dominant replicon detected together with 13 other types of plasmid replicons. Conjugative plasmids (1-3 plasmids of ~3-100 kb) were obtained from 27 of 43 K. pneumoniae isolates. An ESBL gene (either CTX-M-15, CTX-M-3 or SHV-12) was detected from each transconjugant. Co-detection with at least one of other antibiotic resistance determinants [sul1, dfrA, aacC2, aac(6')-Ib, aac(6')-Ib-cr and qnrB] was noted in most conjugative plasmids. The transconjugants were resistant to multiple antibiotics including β-lactams, gentamicin and cotrimoxazole, but not ciprofloxacin. This is the first study describing the characterization of plasmids circulating in Malaysian multidrug resistant K. pneumoniae isolates. The results of this study suggest the diffusion of highly diverse plasmids with multiple antibiotic resistance determinants among the Malaysian isolates. Effective infection control measures and antibiotic stewardship programs should be adopted to limit the spread of the multidrug resistant bacteria in healthcare settings.

Epidemiology and molecular characterization of nosocomially transmitted multidrug-resistant Klebsiella pneumoniae

Parasakthi N, Vadivelu J, Ariffin H, Iyer L, Palasubramaniam S, Arasu A

Int J Infect Dis, 2000;4(3):123-8.
PMID: 11179914

OBJECTIVES: To describe the epidemiology, antimicrobial susceptibility, genomic profiles, and control of a nosocomial outbreak of multidrug-resistant Klebsiella pneumoniae (MRKP) that occurred in the pediatric oncology unit of the University of Malaya Medical Centre in Kuala Lumpur.
MATERIALS AND METHODS: A prospective epidemiologic and microbiologic study was conducted of MRKP isolated from the blood and wound of a boy with necrotizing fasciitis after a 7-day course of ceftazidime and amikacin. In the following 2 weeks, phenotypically similar MRKP were isolated from the blood cultures of four other patients and rectal swabs of another three patients and two liquid soap samples located in the same ward.
RESULTS: Antimicrobial profiles demonstrated that all the isolates were resistant to ceftazidime, sensitive to imipenem and ciprofloxacin, and confirmed to be extended-spectrum beta-lactamase producers. Plasmids of varying molecular weights were present in all isolates. In eight of these isolates, which included four from blood, there were common large molecular weight plasmids ranging from 80 kb to 100 kb. Pulsed-field gel electrophoresis analysis using XbaI demonstrated six different DNA profiles, A to F. Profile A was shared by two blood culture isolates and were related by 91%. Profile B was found in one rectal swab isolate and one isolate from liquid soap and were related by 94%. Profile C was shared by one blood isolate and one liquid soap isolate and showed 100% relatedness. Profiles D, E, and F each were demonstrated by one blood isolate and two rectal swab isolates, respectively. These showed only 65% relatedness.
CONCLUSIONS: The MRKP strains in this outbreak were not clonal in origin. The decline of the outbreak after 4 weeks was attributed to the reemphasis of standard infection control procedures and the implementation of a program that addressed sites of environmental contamination.

Fulltext Neonatal septic arthritis

Halder D, Quah BS, Malik AS, Choo KE

Southeast Asian J. Trop. Med. Public Health, 1996 Sep;27(3):600-5.
PMID: 9185277

Neonatal septic arthritis has always been considered as separate from its counterpart in older children. The condition is uncommon but serious. Affected neonates usually survive, but with permanent skeletal deformities. Ten cases of neonatal septic arthritis were diagnosed between January 1989 and December 1993 in the neonatal intensive care units of two referral hospitals in the state of Kelantan, Malaysia. All except one neonate was born prematurely. The mean age of presentation was 15.6 days. Joint swelling (10/10), increased warmth (7/10) and erythema of the overlying skin (7/10) were the common presenting signs. Vague constitutional symptoms preceded the definitive signs of septic arthritis in all cases. The total white cell counts were raised with shift to the left. The knee (60%) was not commonly affected, followed by the hip (13%) and ankle (13%). Three neonates had multiple joint involvement. Coexistence of arthritis with osteomyelitis was observed in seven neonates. The commonest organism isolated was methicillin resistant Staphylococcus aureus (9/10). Needle aspiration was performed in nine neonates and one had incision with drainage. Follow up data was available for five neonates and two of these had skeletal morbidity. Early diagnosis by frequent examination of the joints, prompt treatment and control of nosocomial infection are important for management.

Fulltext Methicillin-resistant Staphylococcus aureus (mrsa) in a Malaysian hospital

Cheong I, Tan SC, Wong YH, Zainudin BM, Rahman MZ

Med J Malaysia, 1994 Mar;49(1):24-8.
PMID: 8057986

Between August 1990 to November 1991, 905 of 2583 (35.4%) isolates of Staphylococcus aureus were found to be methicillin-resistant in a general hospital in Malaysia. A detailed study of 539 of these isolates showed a high prevalence of methicillin resistant Staphylococcus aureus (MRSA) in the surgical/orthopaedic wards, paediatric wards and the special care unit. The yield of MRSA was highest from wounds/ulcers/skin swabs accounting for 64.2 per cent followed by 6.9 per cent in blood cultures. Vancomycin remains the drug of choice with no resistance detected. The resistance to ciprofloxacin was 6.7 per cent, rifampicin 4.5 per cent and fusidic acid 2.0 per cent. Most isolates were resistant to aminoglycosides. In view of the high prevalence of MRSA in this hospital, the authorities must introduce more effective measures to control its spread as a nosocomial pathogen. Otherwise it may seriously disrupt the efficient delivery of health care services in the country.

Fulltext Early onset neonatal septicaemia in a level II nursery

Malik AS, Pennie RA

Med J Malaysia, 1994 Mar;49(1):17-23.
PMID: 8057985

A prospective study of 486 high risk neonates admitted to a level II nursery in a relatively poor and rural area of Malaysia was carried out to determine the incidence, the spectrum of micro-organisms and predisposing factors in relation to early onset septicaemia. The incidence of proven or probable septicaemia was 57.61 per 1000 high risk newborns over 1.5 kg. The case fatality was 10.71 per cent. Coagulase negative staphylococci, Streptococcus Group B and Klebsiella species were the most commonly isolated organisms. Meconium staining of liquor was the most common risk factor for admission to the nursery, and prematurity was the most significant risk factor for early neonatal infection (P < 0.005) followed by small for gestational age (P < 0.04). Although the incidence of septicaemia was quite high in the level II nursery, the mortality rate was comparable to established figures.
