 Abstract

The investigation into the profiling of antimicrobial resistance in E. coli surpasses the study on the Production of laying chickens due to its potential ramifications on the poultry industry’s finances. The excessive administration of drugs in poultry farming has led to the emergence of antimicrobial resistance (AMR), which ultimately renders treatment of infectious diseases ineffective and may even result in fatalities. To tackle this issue, this study aimed to eradicate and determine the prevalence of E. colispp in samples from laying chickens, while also examining the rates of antimicrobial sensitivity and resistance shown by selected drugs. In order to accomplish this, a cross-sectional study design was employed, and Excel and STATA software was utilized for data analysis. The findings of this study revealed that E. coli were present in 95% of the 200 samples that tested positive, while the remaining 5% yielded negative results. Moreover, 287 isolates identified from the 200 swab samples with 59.6% classified as E. coli. Among these isolates, a significant 100% sensitivity to AM, 75% to AU, 69% to OFX, and 86% to CPX whereas E. colispp was also found to be resistant to Septrin (94%), CN to 88%, and other antibiotics as well. It is noteworthy that the drug susceptibility experiment identified at least 19 patterns of multidrug resistance, which indicates the improper and excessive use of medications.
