| Abstract | ||
| Escherichia coli (E. coli) is one of the most important food-borne pathogens, and especially in frozen chickens meat. Consequently, this study was conducted to isolate and identify (by using cultural and biochemical tests) E. coli from frozen chickens meat samples were available at local markets (retail stores) in different regions of Maisan governorate. Antimicrobial susceptibility testing was determined by using the disc diffusion method. A total of two hundred and fifty-six (256) E. coli isolated and identified. The main objective of this study was to investigate the susceptibility of the E. coli isolated to fluoroquinolones (Norfloxacin, Nalidixic acid, Enrofloxacin, Ciprofloxacin and Ofloxacin). Results from this study showed that these isolates were found to be highly resistant to the average percentages of resistance for all types of Fluoroquinolones. These results give significantly (p < 0.05) high levels of E. coli resistance in the frozen chickens meat. However, there was a trend towards higher resistance frequency to the average percentages of Norfloxacin, Nalidixic acid, Enrofloxacin, Ciprofloxacin and Ofloxacin which are reached (58.23, 49.27, 47.90, 17.22 and 11.42%) respectively. In conclusion, The antimicrobial usage is considered the most important factor promoting the emergence, selection and dissemination of antimicrobial-resistant microorganisms in chicken meat | ||
