Prevalence of Extended Spectrum B-Lactamases in Hospitalized Patents and Community Patients
Objectives: This study was carried out to detect extended spectrum B-lactamases (ESBLs) among Gram negative bacteria isolated from hospitalized patients and community patients (OPD) by double disc synergy test and phenotypic confirmatory test.
Methodology: This cross-sectional, prospective study was carried out in the Department of Microbiology. Dhaka National Medical College, over a period of 1 (one) year 2016. Urine samples were collected from patients. Urine samples were from hospitalized patients and community patients. Samples were collected from in-patient and outpatient department of Dhaka National Medical College Hospital having clinical symptoms of microbial infection. Samples were collected from both sexes and different age groups.
Result: Total 220 urine samples were collected from suspected cases of urinary tract infection. Total 132 (60%) Gram negative bacteria were isolated from these patients as causative agents. Among the isolates, 88 (75.86%) in hospitalized patients and 44 (42.31%) in community patients were isolated. Out of 132 Gram negative bacteria, 31 (23.48%) were ESBL producers. The percentage of ESBL producing bacteria was (31.81%) in hospitalized patients and (6.82%) in community patients.
Conclusion: In the present study, it was observed that considerable numbers of ESBL producing bacteria were detected from urinary tract infection cases. These cases indicate ESBLs will be major threat for antibiotic therapy.
