Prevalence and genomic insights into Yersinia enterocolitica in Southeastern China (2008-2022).

ABSTRACT: Yersinia enterocolitica is a significant foodborne pathogen causing gastrointestinal illnesses worldwide. This study investigates the prevalence and genomic characteristics of Y. enterocolitica to assess potential health risks in southeastern China, a region lacking mandatory yersiniosis monitoring. From 2939 samples collected between 2008 and 2022, 105 isolates were recovered. The highest prevalence was found in rodents (8.1%), followed by retail meats (7.1%), other foods (3.7%), and human clinical cases (0.8%). In addition to meats and rodents, ready-to-eat salads, seafood, and frozen food products were identified as potential transmission vehicles. Various bioserotypes and sequence types (STs) was identified, including twelve previously unreported STs. Biotype 1A, exhibiting greater gen
