Antibiotic-resistant Salmonella spp. from human and non-human sources in Oman

We investigated the antibiotic resistance of various strains of Salmonella isolated from different sources in Oman, namely sewage water, chicken and food handlers. Of 1242 isolates from food handlers, 15 [1.2%] were resistant to one or more antibiotic. Of these, 41% were resistant to ampicillin, 42% to co-trimoxazole and 22% to chloramphenicol. None of the isolates was resistant to ciprofloxacin. Of 515 isolates from chicken and 432 from sewage water, 23.7% and 14.1% respectively were resistant to one or more antibiotic. Susceptibility to the different antibiotics varied but none of the isolates from chicken was resistant to amikacin
