Publication Multidrug Resistant Escherichia coli among Urinary Samples of Patients with Urinary Tract Infection in the Microbiology Department of a Tertiary Care Center: A Descriptive Cross-Sectional Study(Nepal Medical Association, 2023) Chaudhary, Raina; Pradhan, Manoj; Bhatta, Sabita; Shrestha, Sabnum; Adhikari, Nabaraj; Singh, Yengkokpam IbotombaAbstract Introduction: Urinary Tract Infection one of the most common and manageable infections still holds its position as a major public health issue worldwide due to an increase in the number of multidrug resistant bacteria. This study aims to find out the prevalence of multidrug resistant Escherichia coli among urinary samples of patients with urinary tract infections in the microbiology Department of a tertiary care center. Methods: A descriptive cross-sectional study was carried out at a tertiary care centre from 8 August 2018 to 9 January 2019. Ethical approval was received from the Institutional Review Committee (Reference number: 123/2018). Clinically suspected cases of urinary tract infection were included in this study. A convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated. Results: Among 594 patients with urinary tract infections, the prevalence of multidrug resistant Escherichia coli was 102 (17.17%) (14.14-20.20, 95% Confidence Interval). Out of which, the production of extended-spectrum beta-lactamase and AmpC beta-lactamase were observed in 74 (72.54%), and 28 (27.45%) isolates respectively. The co-production of extended-spectrum beta-lactamases/AmpC was observed in 17 (16.67%). Conclusions: The prevalence of multidrug resistant Escherichia coli among patients urinary samples of patient with urinary tract infection was lower as compared to the other studies done in similar settings.Publication Multidrug-resistant among Non-Fermenting Gram-negative Bacteria Isolated in the Department of Microbiology of a Tertiary Care Centre(Nepal Medical Association, 2023) Bhatta, Sabita; Pradhan, Manoj; Chaudhary, RainaAbstract Introduction: Infection caused by Non-fermenting Gram-negative bacteria (NFGNB) like Pseudomonas aeruginosa and Acinetobacter baumannii leads to life-threatening conditions. These bacteria are often multidrug-resistant which leads to limited therapeutic options leading to treatment failure. Little information is available regarding the prevalence and resistance pattern of such bacteria in our country. The aim of the study was to find out the prevalence of multidrug-resistant among non-fermenting Gram-negative bacteria isolated in the Department of Microbiology of a tertiary care centre. Methods: A descriptive cross-sectional study was conducted in the Department of Microbiology of a tertiary care centre from 1 September 2021 to 30 August 2022 after obtaining ethical approval from the Institutional Review Committee. All samples received in the Microbiology laboratory for diagnostic purposes were included. A convenience sampling method was used. The point estimated was calculated at a 95% Confidence Interval. Results: Among 412 non-fermenting Gram-negative bacteria, multidrug resistance was observed in 373 (90.53%) (87.70-93.36, 95% Confidence Interval) isolates. Among 373 isolates, Acinetobacter baumannii was 253 (67.83%) and Pseudomonas aeruginosa was 120 (32.17%). Conclusions: The prevalence of multidrug-resistant non-fermenting Gram-negative bacteria was found to be higher than in the study conducted in similar settings.
