Abstract
- Salmonella are a type of bacteria known to cause food-borne illness. Their host range varies widely, and their susceptibility to the host determines its pathogenicity. Salmonella enterica serovar Rissen (S. Rissen) is a widely distributed serotype; however, its virulence and pathogenicity are poorly understood. In this study, the pathogenicity and antibiotic resistance of a representative S. Rissen isolate were investigated. The cell model results showed that S. Rissen preferred to replicate in human macrophage cells U937 compared to murine macrophage cells RAW264.7, suggesting that it has a level of host adaptability. Genome sequencing and comparison analysis revealed that the distribution and nonsynonymous single nucleotide polymorphisms of virulence factors in S. Rissen were similar to those in S. Typhi rather than to those in S. Typhimurium. Taken together, our results suggest that although S. Rissen is a common serotype distributed in swine herds, pork and chicken products, it has strong ability to infect humans. [ABSTRACT FROM AUTHOR]
