Genetic analysis of non-hydrogen sulfide-producing Salmonella enterica serovar typhimurium and S. enterica Serovar infantis isolates in Japan

Abstract

Whole-genome sequencing of non-H2S-producing Salmonella enterica serovar Typhimurium and S. enterica serovar Infantis isolates from poultry meat revealed a nonsense mutation in the phsA thiosulfate reductase gene and carriage of a CMY-2β-lactamase. The lack of production of H2S might lead to the incorrect identification of S. enterica isolates carrying antimicrobial resistance genes. Copyright © 2013, American Society for Microbiology.
