Pathogenic Yersinia enterocolitica O:3 isolated from a hunted wild alpine ibex


Joutsen, S; Sarno, E; Fredriksson-Ahomaa, M; Cernela, N; Stephan, R (2013). Pathogenic Yersinia enterocolitica O:3 isolated from a hunted wild alpine ibex. Epidemiology and Infection, 141(03):612-617.

Abstract

Occurrence of Yersinia spp. in wild ruminants was studied and the strains were characterized to get more information on the epidemiology of enteropathogenic Yersinia in the wildlife. In total, faecal samples of 77 red deer, 60 chamois, 55 roe deer and 27 alpine ibex were collected during 3 months of the hunting season in 2011. The most frequently identified species was Y. enterocolitica found in 13%, 10%, 4% and 2% of roe deer, red deer, alpine ibex and chamois, respectively. Interestingly, one Y. enterocolitica O:3 strain, isolated from an alpine ibex, carried the important virulence genes located on the virulence plasmid (yadA and virF) and in the chromosome (ail, hreP, myfA and ystA). Most of the Y. enterocolitica strains belonged to biotype 1A of which 14 were ystB positive. Further studies are needed to clarify the importance of alpine ibex as a reservoir of pathogenic Y. enterocolitica.
