| dc.description.abstract | Background: One of the largest risks to world health is the spread of microorganisms that are resistant to drugs. According to estimates, the mortality rate from Carbapenem-resistant Klebsiella pneumonia (CRKP) infections ranges from 37.2% to 42.1%. In 2019, Ethiopia reported 21,200 deaths directly attributable to Anti-microbial resistance. Objectives: To assess multidrug resistance and carbapenemase producing Enterobacteriaceae on clinical samples referred to Wudassie Advanced Medical Laboratory. Method: A cross-sectional study was conducted from December 2024 to March 2025. A total of 1105 patients from which 439 were suspected of sepsis, 110 suspected of wound infection, 45 suspected of meningitis, 353 suspected of urinary tract infection and 153 suspected of other infections, whose specimens were sent to wudassie advanced medical laboratory during the study period were included in this study. Isolates were identified using Matrix-Assisted Laser Desorption & Ionization- Time of Flight (MALDI-TOF) (EXS 3000, Zybio Inc., China). Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion technique and carbapenemase production was confirmed by modified carbapenem inactivation technique. Data entered using epi data version 4.6 and analyzed using Statistical Package for social sciences statistical software version 26 and the result was displayed with graphs, tables and words and compared with previous studies. Result: Out of 1105 eligible patients, 288 of them had microbial growth. Of this,156 of them were Enterobacteriaceae. The predominant isolate was E. coli followed by K. pneumoniae and P. mirabilis. From 156 Enterobacteriaceae isolated, 78.8% of them were multidrug resistant and 19.5% of them were carbapenemase producing Enterobacteriaceae (CPE). K. pneumoniae was the most abundant CPE isolate. Most of CPE producing isolates were from urine specimen followed by wound and sputum specimen. Conclusion: The findings highlights a high prevalence of multidrug-resistance and a rise in the prevalence of carbapenemase-producing Enterobacteriaceae, Thus, it is important to review current treatment guidelines for better patient management and outcome. | |
