Detection of Extended spectrum beta lactamase (ESBL) enzyme producing bacteria in hospital settings is vital as ESBL genes are transmissible. This study was carried out to determine the distribution of ESBL producing gram negative isolates at a tertiary care hospital in Dhaka city which deals with the patients hailing from relatively low socioeconomic status.Onehundred and twenty four gram negative bacteria isolated from different clinical specimens from outpatient and inpatient departments of Sir Salimullah Medical College and Mitford Hospital (SSMC & MH) were tested for ESBL by E test ESBL method in the department of microbiology of Sir Salimullah medical college (SSMC) from March 2013 to August 2013.Out of 124 gram negative bacteria 69 (55.65%) were positive for ESBL. Among the ESBL producers, Esch.coli was the highest (46.38%) which was followed by Serratia spp (11.59%), Enterobacter spp (10.14%), Proteus spp, (8.70%), Acinetobacter spp.(7.24%) and Klebsiella spp.(5.79%). Out of 32 Esch.coli isolated from outpatient department, 10 (31.25%) were positive for ESBL. On the other hand out of 27 Esch. coli isolated from inpatient department, 22 (81.48%) were positive for ESBL. The difference was statistically significant (p<0.001).So the present study reveals that the distribution of ESBL producers is more among the hospitalized patients than the patients of the community.Bangladesh J Med Microbiol 2016; 10 (1): 8-12

Introduction: Klebsiella pneumoniae is one of the most common Gram negative bacteria encountered byclinicians worldwide as a cause of infections in human. Most of the infections are acquired in hospital settingtherefore, it is reported to be the amongst the 10 most common nosocomial pathogen in various studies. Nowadays,Klebsiella pneumoniae infections are complicated by increase in Extended Spectrum Beta Lactamase (ESBL)producing isolates. Therefore, this study is being conducted with the objective to fi nd out the prevalence ofESBL producing Klebsiella pneumoniaein various clinical samples and to fi nd out there sensitivity pattern.Methods: A total of 100 Klebsiella pneumoniae were isolated from various samples during the period of April2013 to November 2013 in Microbiology Unit of Shree Birendra Hospital. All the isolates were identifi ed withtheir sensitivity pattern according to standard methodology. Combination disc diffusion method was followedfor identifi cation of ESBL.Results: Out of total 100 isolates of Klebsiella pneumoniae21% were ESBL producer.ESBL producer isolatesshowed 100% sensitivity to Imepenem followed by Amikacin 57.1% and Chloramphenicol 47.6%. All theESBL isolates were resistant to both Cefotaxime and Ceftazidime.Conclusions: ESBL producer Klebsiella pneumoniae isolates were multidrug resistant. Continuous surveillanceand timely intervention with discouraging the use of cephalosporin group of antibiotics is mandatory.doi:  http://dx.doi.org/10.3126/mjsbh.v13i1.12996

Background: A major problem in the treatment of the infectious diseases healthcare centers is extended-spectrum beta-lactamase (ESBL)-producing bacteria. Objectives: The aim of present study was to identify the antibiotic sensitivity pattern and prevalence of the blaCTX, blaTEM, and blaSHV genes in Escherichia coli and Klebsiella pneumoniae strains. Methods: In this study, E. coli and K. pneumoniae specimens were collected in Shushtar hospitals, Khuzestan (southwest Iran), from March to October 2015. Sensitivity antibiotic pattern performed by disc diffusion method. Double disc synergy test (DDST) done for identifying ESBLs isolates and PCR for blaTEM, blaSHV, and blaCTX-M genes. Results: One hundred E. coli and 30 K. pneumoniae isolates were collected from different specimens. The highest rates of antibiotic resistance related to cefotaxime and aztreonam in E. coli and K. pneumoniae. ESBL-harboring K. pneumoniae and E. coli were 13.5 and 28%, respectively. Overall, bla TEM was the most prevalent ESBL gene. Conclusions: In this study, the rate of antibiotic resistance was high, and due to the carrying of coding genes on mobile genetic elements and the ability of these elements to carry genes that create resistance to other antibiotic families, identification and isolation of these isolates are essential to find effective antibiotics and eliminate the infection.
