One hundred fifty-three wild boars shot in the canton of Geneva, Switzerland, were studied for the occurrence of foodborne pathogens. Tonsils and fecal samples of the animals were examined using real-time polymerase chain reaction, enzyme-linked fluorescent immunoassay, and cultural methods. The detection rate of Salmonella spp., Yersinia enterocolitica, Yersinia pseudotuberculosis, stx-positive Escherichia coli, and Listeria monocytogenes was 12%, 35%, 20%, 9%, and 17%, respectively, when tonsil samples were studied. Only Y. enterocolitica (5%) and L. monocytogenes (1%) were detected in fecal samples. None of the samples was positive for Campylobacter spp. Females (71%) and young animals (61%) carried more frequently one or more pathogens than males (53%) and older ones (44%). In total, 8 Salmonella spp., 14 Y. enterocolitica, 4 Y. pseudotuberculosis, and 26 L. monocytogenes strains were further characterized. Most of the Salmonella spp. strains were of serotype Salmonella Enteritidis (75%) followed by serotypes Salmonella Stourbridge (13%) and Salmonella Veneziana (13%). L. monocytogenes strains belonged to serotypes 1/2a (42%), 1/2b (19%), and 4b (38%). Serotypes O:3 (36%), O:5,27 (21%), and O:9 (29%) were identified among Y. enterocolitica strains and serotypes O:1 (75%) and O:2 (25%) among Y. pseudotuberculosis strains. This study shows that wild boars are frequent carriers of foodborne pathogens. High wild boar densities and increasing popularity of outdoor ranging of pigs may intensify the risk of transmission of these pathogens to fattening pigs.

is a bacteria responsible for a widespread zoonosis that affects both humans and animals. Leptospirosis is a challenging pathology to diagnose and treat since its signs are unspecific and symptoms vary greatly. The disease seems to be highly prevalent in environments where reservoir animals such as rats and small mammals are common.

The skin functions as the body's primary defense barrier; when compromised, it can lead to dehydration, infection, shock, or potentially life-threatening conditions. Miniature pigs exhibit skin characteristics and healing processes highly analogous to humans. Mesenchymal stem cells contribute to skin injury repair through a paracrine mechanism involving exosomes.

Rotavirus A (RVA) is the primary enteric pathogen of humans and many other species. However, RVA interspecies transmission remains poorly understood. In this study, we conducted a comprehensive screening and genotyping analysis of RVA in 1706 wild animal samples collected from various regions within Yunnan Province, China.

Hunting dogs are exposed to the risk of injury in driven hunts, an often-used method for managing growing wild boar numbers. This study investigated the impact of increased hunting pressure-both across the hunting season and within individual hunting events-on the risk of wild boar attacks on hunting dogs, i.e.

Wild boars inhabit diverse climates, including frigid regions like Siberia, but their migration history and cold adaptation mechanisms into high latitudes remain poorly understood. We constructed the most comprehensive wild boar whole-genome variant dataset to date, comprising 124 samples from tropical to frigid zones, among which 47 Russian, 8 South Chinese and 3 Vietnamese wild boars were newly supplemented. We also gathered 75 high-quality RNA-seq datasets from 10 tissues of 6 wild boars from Russia and 6 from southern China.
