title: Food-borne zoonotic pathogens and antimicrobial resistance of indicator bacteria in urban wild boars in Barcelona, Spain.
abstract: Wildlife is increasingly abundant in urban environments, but little is known about the zoonotic pathogens carried by these populations. Urban wild boars are of particular concern because this species is well-known as a pathogen reservoir, and thus, we studied selected zoonotic pathogens in urban wild boars in Barcelona, Spain (n=41). Salmonella enterica was found in 5.00% (95% CI 0.61-16.91) and Campylobacter coli in 4.88% (95% CI 0.6-16.53) of the animals. E. coli O157:H7 and C. jejuni were not found. Other thermophilic Campylobacter were moderately prevalent (19.51%, 95% CI 8.82-34.87). Additionally, we screened for antimicrobial resistance in indicator bacteria: resistance was most frequent in Enterococcus faecium (95% of the isolates were resistant to at least one antimicrobial agent), followed by Enterococcus faecalis (50%) and Escherichia coli (10%). For the first time resistance to linezolid in bacteria carried by wildlife is reported. These findings pose a concern for public health, and thus, further research is needed on wildlife in urban environments.
