ABSTRACT

Kechagia N, Chatzipanagiotou
S, Genomic DNA of Yersinia enterocolitica from
pigs and humans.. Onl J Vet Res., 30 (4):
228-232, 2026. Pig strains (116) of Yersinia enterocolitica
serotype O:3/biotype 4 were isolated from slaughterhouses tested for XbaI
restriction fragment length polymorphism (RFLP) profiles by pulsed field gel
electrophoresis (PFGE). The genetic profiles from pigs were compared to those
from human clinical isolates of the same bio-serogroup. PFGE analysis revealed
2 different genetic profiles strain A1 (99.14%) and strain A2 (0.86%). A1 was
similar to the unique genetic profile described in human clinical isolates previously.
As this profile was derived exclusively from the pigs, this result supports the
assumption that pigs seem to be the main reservoir of human pathogenic yersiniae.
