Fatal atypical O:3 Yersinia pseudotuberculosis infection in cynomolgus macaques.

Zao CL, Tomanek L, Hurtado-McClure G, Cooke A, Berger R, Boulineau TM, Turner OC, Covington DE.  Abstract Fatal Yersinia pseudotuberculosis infection in cynomolgus macaques was diagnosed based upon pathology, microbiology and PCR for this study. Pathological findings included acute, erosive to ulcerative, necrohemorrhagic enterocolitis. Genotyping by PCR showed an O:3 pattern (gmd-fcl(+), ddhC-prt(+), manB(+), ddhA-B(+)), but an additional gene, wbyK, was detected. This is the second report to identify wbyK+ O:3 genotype as the cause of fatal yersiniosis. The first case was reported in 2008, and involved farm deer in the U.S. As the frequency of wbyK+ O:3 genotype is found more often in different carriers, O:3 genotype [...]
