Study of Zoonotic Enteric Pathogens ofin Tenerife, Canary Islands, Spain.

Abstract

is an invasive species in the Canary Islands (Spain). There are few studies about the zoonotic pathogens this species could be hosting; therefore, this study was focused on analyzing causative agents of diarrhea in humans in feces from hedgehogs. A total of 45 fecal samples obtained in Tenerife (Canary Islands) were analyzed in this study using Biofire FilmArray gastrointestinal panel with an integrated Biofire FilmArray system. Forty-two (93.33%) of the samples presented at least one of the pathogens detected by the panel. The prevalence of four bacteria stands out as for enteropathogenic(71.11%),(66.67%),(33.33%), andsp. (22.22%), all of which were widely distributed along Tenerife. Besides, other pathogens were found,sp. and enterotoxigeniclt/st in 6.66% of the animals,/enteroinvasivein 4.44%, andGI/GII,, andsp. in 2.22%. Of the hedgehogs, 26.66% were hosting just one pathogen, and the others showed coinfection: 24.44% hosted two, 31.11% hosted three, and 11.11% hosted four or more. The close contact with hedgehogs may imply the transmission of not only one causative agent of diarrhea but also multiple agents, since coinfection is highly prevalent. The lack of management measurements for this animal in the Canary Islands, the common habit of adopting hedgehogs from wildlife without veterinary control, and the fact that most of the hedgehogs studied belonged to highly populated areas imply a high risk of transmission of pathogens to humans.
