Role of exotic felids as carriers of multidrug-resistant Salmonella Newport.

Chronic salmonellosis in exotic felids is uncommon. In a recent article in ASM Case Reports (2:e00098-25, 2025, https://doi.org/10.1128/asmcr.00098-25), B. L. S. Stenger, D. R. Evans, S. J. Gefroh, A. Breuer, et al. published a report on multidrug-resistant (MDR) Salmonella enterica serovar Newport, persisting strain REPJJP01 isolated from two snow leopards (Panthera uncia) and a Pallas's cat (Otocolobus manul) in two separate regional zoos. Salmonella Newport causes human and animal enteric disease, but this particular strain has not been isolated from felids before. The reported cases highlight the value of genotypic and phenotypic techniques to identify shared and potentially MDR strains of Salmonella from human and animal hosts.
