Distribution of enteropathogenic Yersinia spp. and Salmonella spp. in the Swedish wild boar population, and assessment of risk factors that may affect their prevalence.

摘要: Pure Eurasian wild boars and/or hybrids with domestic pigs are present in the on most continents. These have been demonstrated to carry a large number of zoonotic and epizootic pathogens such as Salmonella spp., Yersinia enterocolitica Y. pseudotuberculosis. Wild boar populations throughout Europe growing more meat is being consumed, majority within homes hunters without having passed veterinary inspection. The aim this study was investigate if factors population density, level artificial feeding, time since establishment given population, handling animal by-products from slaughtered animals could influence presence these boar. In total, 90 30 different Sweden were sampled analysed using protocol combining pre-cultivation PCR-detection. results showed that 27% positive for 31% 22% 80% populations, at least one enteropathogens 60% carried investigated enteropathogens. presumptive risk case–control approach, however, no significant associations found. Human commonly by boars, mainly tonsils, can thus constitute contamination carcass during slaughter. Based results, effect reducing densities feeding places might be limited.
