| dc.description.abstract | Escherichia coli O157 and non-typhoidal Salmonella are common cause of food-borne diseases worldwide. They cause acute gastroenteritis when ingested with contaminated food such as raw meat and meat products. They are also responsible for the emergence of antimicrobial resistance both in human and veterinary medicines. The objective of this study was to isolate, identify and determine antimicrobial sensitivity profile test of non-typhoidal Salmonella and Escherichia coli O157 in Bishoftu. Seven hundred (700) samples from abattoirs containing carcass swabs (n=420), pooled hide swab (n=140) and feces (n=140) were collected and processed using standard procedures. The overall occurrence of Escherichia coli O157 and non-typhoidal Salmonella were 4.29% and 4.57%, respectively. The occurrence in feces, hide and carcass swabs were 10%, 4.29 %, and 2.38% for Escherichia coli O157 and 7.14%, 7.14% and 2.86% for non-typhodal Salmonella, respectively. There was no statically significant variation among sample types and between abattoirs. The antimicrobial susceptibility test showed that Escherichia coli 157 isolates were 100% sensitive to Ciprofloxacin and Gentamicin. All of isolates were resistant to Cloxacillin, Ampicillin, Streptomycin and Polymyxin-B. But, 60%, 73.3%, 93.3%, 73.3%, 53.3%, 6.7% were susceptible to Tetracycline, Trimethoprim, Chloramphenicol, Kanamycin, Rifampicin, and Streptomycin, respectively. All non-typhoidal Salmonella species were susceptible to trimethoprim, ciprofloxacin and Gentamicin while resistant to Cloxacillin, Cephalothin, Rifampicin, Ampicillin, Streptomycin and Polymyxin-B. But, 50%, 43.8 % and 56.25% were susceptible to Tetracycline, Chloramphenicol and Kanamycin, respectively. The study showed that the occurrences of Escherichia coli O157 and non-typhoidal Salmonella in the study area and their resistance to the commonly used drugs. Therefore, adequate hygienic practices at abattoirs, applying food safety procedures and rational use of drug were recommended. | en_US |
