Prevalence of Shiga toxin-producing Escherichia coli, Salmonella spp. and Campylobacter spp. in large game animals intended for consumption: relationship with management practices and livestock influence.

摘要: Although wild ruminants have been identified as reservoirs of Shiga-toxin producing Escherichia coli (STEC), little information is available concerning the role Salmonella spp. and Campylobacter in large game species. We evaluated presence these pathogens faeces (N=574) carcasses (N=585) sampled from red deer (N=295), boar (N=333) other ungulates (fallow deer, mouflon) (N=9). Animal sampling was done situ 33 hunting estates during two seasons. strains associated with human campylobacteriosis were infrequently detected indicating that both had a limited zoonotic risk our study area. The overall STEC prevalence animals 21% (134/637), being significantly higher (90 out 264). A total 58 isolates serotyped. Serotypes O146:H- O27:H30 most frequent majority serotypes previously found infection, including serotype O157:H7. livestock (p<0, 01) where high densities (p<0.001) present. To best knowledge, this first reporting occurrence animals. Furthermore, confirmed by pulsed-field gel electrophoresis (PFGE) cross contamination carcass dressing occurred, implying likelihood entering into food chain.
