Salmonella infections are a significant public health concern worldwide, with poultry and poultry products being the primary sources of transmission. In Kazakhstan, data on the prevalence of Salmonella in poultry farms and the antimicrobial resistance of the isolates remain limited. In this study, we isolated and identified Salmonella strains from samples collected from poultry farms in the northern region of Kazakhstan and assessed their antimicrobial resistance profiles. The samples were cultured on differential diagnostic media, and the resulting isolates were identified using biochemical tests and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. From the 246 samples examined, 9 pure cultures were isolated and identified as Salmonella enterica subsp. enterica. The following Salmonella serotypes were identified: four isolates of S. enteritidis, one of S. paratyphi C, one of S. moscow, two of S. infantis, and one of S. mbandaka. These isolates exhibited multidrug resistance to several antibiotics including rifampicin, azithromycin, erythromycin, vancomycin, cefadroxil, cefuroxime, cefaclor, cephalothin, clarithromycin, doxycycline, cefazolin, clindamycin, kanamycin, streptomycin, nitrofurantoin, and piperacillin. In addition, all the isolates demonstrated moderate resistance to penicillin and tetracycline. These results provide insights into the species composition of circulating strains and their resistance patterns, which can contribute to the development of effective antimicrobial therapeutic strategies in poultry farming.
