Antimicrobial resistance is a budding threat worldwide. The every class of antibiotic agents must have resistance mechanisms.The principal mechanism for resistance to the β-lactam antibiotics in gram-negative bacteria is the production of β-lactamase. The creation of extended-spectrum β-lactamases (ESBLs) is a vital mechanism which is responsible for the resistance to the cephalosporins. During the last 2 decades, ESBL producing gram-negative bacilli have arose as a major problem in many settings. Resistance to 3rd generation cephalosporins by attainment and manifestation of extended spectrum beta lactamase (ESBL) enzymes among gram-negative bacilli is on a rise. To isolate the ESBL strains from various clinical samples in ICU. To find out the prevalence of ESBL producing gram negative bacilli during the period of December 2017 - December 2018 in the Intensive care unit of Sree Balaji Medical College and Hospital. Totally 27 out of 139 gram negative bacilli (19.42%) were found to be ESBL producers. ESBL triggering gram negative bacilli spiteful the biological sample like blood,  urine, wound  swab, sputum  were 36.36%, 16.00%, 10.00%, 9.09% individually Though Meropenem is 100% sensitive to all ESBL beginning gram negative bacilli, but still sensitivity also witnessed with some cheaper drugs like Cotrimoxazole (33.33%), Amikacin (48.14%), Gentamicin (40.7%), Ciprofloxacin (22.22%). Hence we care and will provide an analysis and treatment for affected patients with Extended Spectrum Beta Lactamase producing organisms.

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

Sensitivity Pattern

 Background: Empirical antibiotics are used in the intensive care unit based on developing countries’ guidelines due to a lack of a bacteriological profile of individual ICU and institution policy. Therefore, this study was conducted to know the antibiogram of the intensive care unit and to make institution policy for antibiotic use in ICU. Materials and methods: It was a prospective descriptive cross-sectional study conducted in the mixed surgical and medical intensive care unit of a tertiary care hospital for one year in 625 patients. Various clinical samples were collected aseptically and organisms were identified by the cultural characteristics, morphology, gram stain, and different biochemical test. Antimicrobial susceptibility was done with a disc diffusion test. Data collection was done in a preformed sheet that included all tested antibiotic and demographic variables. Statistical analysis was done by using statistical package for the social sciences. The result was presented as frequency and percentage. Results: Out of 625 samples, 135(22%) showed growth in culture. Among them, 96(71%) and 39(29%) were gram-negative bacilli and gram-positive cocci respectively. The tracheal aspirate was the most common type of specimen which comprised 49(36.29%) isolates. The most common organism was Staphylococcus aureus which accounts for 27(20%) isolates, followed by Acinetobacter baumanni 25(18.51%), Klebsiella pneumoniae 22(16.29%) and Pseudomonas aeurignosa 21(15.55%). The incidence of multidrug-resistant and extended drug resistance was 44(32.5%) and 45(33%) respectively. Meanwhile, the incidence of methicillin-resistant staphylococcus aureus was 70%. However, in the case of Acinetobacter baumannii and Enterobacteriaceae, all were sensitive to polymyxin B and meropenem. Conclusion:Antibiotics should be prescribed based on the antibiogram of individual intensive care units that can decrease antibiotic resistance. Polymyxin B and meropenem can be prescribed for gram-negative bacilli and vancomycin for Staphylococcus aureus.

Extended Spectrum beta lactamase producing pathogens are reported in many clinical samples and pose an emerging threat health. To find the prevalence of ESBL producing Enterobactriacea pathogens isolated from inpatients (Medical and Surgical Wards; Hospital stay > 72 h) admitted to Prince, Mutib, Hospital Sakaka, Jouf. A total of 1043 Enterobactriacea were isolated during April 2015 to October 2016 study period. Vitek -2 compact (biomeriux Leon, France) was used for identification and antimicrobial sensitivity (AST) test. A Total of 115/1043 (11.02%) ESBL producing pathogens were isolated from urine 15.07% (n=242), sputum 13.6 % (n=220), wound 10.8% (n=287) and blood 5.4 % (n=294). Klebsiella pneumonia is most dominant followed by E coli and Proteus miribilis. Cephamycins and carbapenems were found most effective (100% sensitivity) against the pathogens isolated. The aminoglycosides, beta lactams and Fluroquinolnes class of antibiotics, microorganisms have gained the resistance of 20%, 22.7%, 40-70% respectively. The infection control measures should be taken seriously and making of effective use of antibiotics is need of hour.
