Abstract
Background: The current study was carried out with the aim to reveal the presence of Escherichia coli (E. coli) and Salmonella species (spp.) in table eggs sold for human use in Peshawar, and their antimicrobial resistance to different drugs used in Pakistan for poultry and human practices. Methods: A total of 80 eggs were bought from different shops. E. coli and Salmonella spp < /em>. were isolated from 85.36% (70) and 14.63% (12) of the total collected egg samples (80), respectively. The antibiotics susceptibility test was done using the disk diffusion method. Results: The shells of eggs showed significantly higher contaminations as compared to egg internal contents for both E. coli and Salmonella spp < /em>. The isolated organism presented a significant resistance to multiple drugs. They were found to be completely resistant to penicillin G, nitrofurantoin, oxacillin, and sulfamethoxazole/trimethoprim. Furthermore, Salmonella spp. was also completely resistant to tetracycline. The susceptibility pattern of both these isolates was quite different for some antimicrobials, as Salmonella isolates were completely sensitive to neomycin, whereas 100% susceptibility was observed in E. coli isolates to amikacin, amoxicillin-clavulanic acid, levofloxacin, and neomycin. In addition, resistance frequency among isolates of E. coli against amoxicillin (77.14%), minocycline (54/28%), streptomycin (80%), and tetracycline (80%), and in Salmonella spp. against amikacin (50%), amoxicillin (66.66%), amoxicillin-clavulanic (66.66%), levofloxacin (33.33%), minocycline (50%) and streptomycin (83.33) were also high. Conclusion: Hence it can be concluded from the present study that the table eggs sold in the markets of Peshawar Pakistan are infected with multidrug resistance (MDR) strains of E. coli and Salmonella spp < /em>.
