The pathogenicity of Yersinia enterocolitica is associated with the presence of plasmid and chromosomal virulence genes. Strains belonging to biotype 1A do not possess pYV plasmids, often harbour the ystB gene and usually lack the ail gene, which is the main virulence marker for Y. enterocolitica. The simultaneous presence of ail and ystB is uncommon. In this study, 21/218 (9.6%) biotype 1A Y. enterocolitica isolates from rectal swabs of wild boar (Sus scrofa; n = 18), red deer (Cervus elaphus; n = 2) and roe deer (Capreolus capreolus; n = 1) in Poland harboured both ail and ystB genes.
小肠结肠炎耶尔森菌的致病性与质粒和染色体毒力基因的存在有关。属于生物型1A的菌株不具有pYV质粒，通常携带ystB基因，且通常缺乏ail基因，而ail基因是小肠结肠炎耶尔森菌的主要毒力标志物。ail和ystB同时存在的情况并不常见。在本研究中，从波兰野猪（Sus scrofa；n = 18）、马鹿（Cervus elaphus；n = 2）和狍（Capreolus capreolus；n = 1）的直肠拭子中分离出的218株生物型1A小肠结肠炎耶尔森菌中有21株（9.6%）同时携带ail和ystB基因。
