Yersinia enterocolitica is the causative agent of yersiniosis, a zoonotic disease of growing epidemiological importance with significant consequences for public health. This pathogenic species has been intensively studied for many years. Six biotypes (1A, 1B, 2, 3, 4, 5) and more than 70 serotypes of Y. enterocolitica have been identified to date. The biotypes of Y. enterocolitica are divided according to their pathogenic properties: the non-pathogenic biotype 1A, weakly pathogenic biotypes 2–5, and the highly pathogenic biotype 1B. Due to the complex pathogenesis of yersiniosis, further research is needed to expand our knowledge of the molecular mechanisms involved in the infection process and the clinical course of the disease. Many factors, both plasmid and chromosomal, significantly influence these processes. The aim of this study was to present the most important virulence markers of Y. enterocolitica and their role during infection.
The purpose of the study was to analyze a part of the nucleotide sequences of ystB gene Y . enterocolitica strains isolated from wild animals. The material for the study consists of 30 Y . enterocolitica biotype 1A strains obtained from different wild animal species and belonging to different genotypes. Phylogenetic analysis of ystB nucleotide sequences belonging to four regular genotypes G1, G2, G3, G4 and to five groups of variations V1, V2, V3, V4, V5 revealed significant differences of Y . enterocolitica strains isolated from wild animals. The most phylogenetically distant were strains belonging to V5.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
