High seroprevalence of anti-Leptospira spp. antibodies in domestic and wild mammals from a mixed use rescue center in Ecuador: Lessons for “One Health” based conservation strategies

Abstract:

Leptospirosis is a zoonotic disease of worldwide distribution that affects humans, domestic and wild animals. This study evaluates the frequency of anti- Leptospira spp. antibodies in companion, livestock and wild mammals from a mixed use rescue center on Guayaquil, the main city of Ecuador. Sera were collected from 23 domestic and 6 wild mammals. All animals tested were seropositive for Leptospira spp. using Microscopic Agglutination Test (MAT), most of them for multiple serovars. Leptospira interrogans serovars Canicola, Hardjo and Icterohaemorrhagiae were the most frequent ones. We conclude that the presence of domestic animals at this mixed use rescue center may cause the exposure of wild animals, considering the high frequency of Leptospira spp. seropositivity already reported for livestock and companion animals in Ecuador. This is the first serological survey for leptospirosis including wild animals rescued from illegal traffic in Ecuador and point out the urgent need of exclusive rescue and conservation units for wild species and the potential role as Leptospira spp. reservoir for wild mammals.
