Chicken’s faeces sample were collected from ten different farms around Koya city between November 25 and December 30, 2017. All samples were cultured and diagnosed by conventional methods; then antibiotic susceptibility test were carried out by agar disc diffusion method. The faecal samples that containing Salmonella spp. were determined and examined against nalidixic acid (30μg), chloramphenicol (10μg), azithromycin (15μg) and amoxicillin (25μg). Resistance in faecal Salmonella spp. to nalidixic acid, chloramphenicol and azithromycin were 100%, 91.6% and 83.3%, respectively. Amoxicillin resistance was observed in 50% of the Salmonella spp., and amoxicillin sensitive was observed in 33.3% of the isolates. The remaining isolates showed 16.7% intermediate resistance to amoxicillin. The results of this study strongly indicate that amoxicillin can be used to inhibit or eliminate any source of foodborn Salmonellas pp. infection.
