Abstract: Salmonella is a most important zoonoticpathogen and its prevalence in animals is a global public health concern. Resistance to widely prescribed antibiotics has grown to be a significant issue for managing chickens and preventing illness. The current study was carried out to determine the presence of Salmonella spp. infection in poultry and to look at the antibiogram patterns of isolates from commercial Layer farms in and around Hyderabad, Telangana. A total of 261 samples of faeces (123) and cloaca (138) were collected and processed for the isolation of Salmonella. Twenty one (8.04%) of the samples tested were found to be positive for Salmonella. Out of 123 fecal samples and 138 cloacal swabs, the incidence of Salmonella spp. was 7.3% and 8.6% respectively. All the isolates were subjected to antibiotic sensitivity tests against 10 antimicrobials. The results revealed that bacterial isolates had 100% sensitivity for ciprofloxacin and enrofloxacin followed by levofloxacin, gentamycin, ampicillin, neomycin and amoxicillin were found to be the most intermediately sensitive antibiotics. Tetracycline, doxycycline and amikacin were the most resistant antibiotics. The biggest challenge at hand is multiple antibiotic resistance because many antibiotics are ineffective against infections caused by Salmonella. Therefore, the goal of the current study was to determine the pattern of antibiotic resistance exhibited by these Salmonella.
