Prevalence and antimicrobial susceptibility of Salmonella in poultry farms and in ‐contact humans in Adama and Modjo towns, Ethiopia

This study investigated the prevalence, serotype distribution, and antimicrobial susceptibility of nontyphoidalSalmonella among poultry farms in Ethiopia. Seventeen farms in Adama and Modjo towns (28.8%), 24 samples from poultry farms (2.9%), and 1/36 of stool samples from humans in contact with poultry (2.8%) were positive forSalmonella. Twenty (80%) and 19 (76%) ofSalmonella isolates were resistant to streptomycin and tetracycline, respectively. Nineteen (76%) of the isolates were resistant to two or more antimicrobials. AbstractConsumption of contaminated poultry and poultry products represents a common source of nontyphoidalSalmonella infection. Little is known on the status ofSalmonella and their antimicrobial susceptibility in poultry farms in Ethiopia. This study investigated the prevalence, serotype distribution, and antimicrobial susceptibility of nontyphoidalSalmonella among poultry farms in Adama and Modjo towns. Three hundred thirty ‐four cloacal swabs, 384 fecal droppings of birds, 59 feed, 59 floor swabs, and 36 stools from in‐contact humans were collected and processed forSalmonella isolation. Isolates were tested for their susceptibility to 15 antimicrobials using Kirby –Bauer disk diffusion assay. Seventeen (28.8%) of the farms and 24 (2.9%) of the samples from poultry farms and 2.8% (1/36) of stool samples of humans in‐contact with poultry were positive forSalmonella. Most of the isolates (n = 21) were recovered from fecal droppings of birds while ...
