Leptospira interrogans is common in wild canids but unknown its effect is in Mexican wild canid populations. This study was realized in a sample of gray foxes (Urocyon cinereoargenteus Schreber, 1775) and coyotes (Canis latrans Say, 1823) in El Cimatario National Park, in Querétaro, a fragment of tropical deciduos forest in the highlands of Central Mexico. A total of 17 wild canids were captured; hemograms, biochemical profiles, and a microagglutination test for L. interrogans serovars were obtained for ten organisms. The animals were positive for eight of the eleven analyzed serovars with very significant titer values. Nevertheless, they lacked physical evidence of this pathogen, and data suggest that these wild canid species are reservoirs of these bacteria. This research potentially reflected the historical influence of domestic animal presence and transmission of Leptospira for centuries in this ecosystem.

Keywords : biochemical profiles; Canis latrans; hemograms; Leptospira interrogans; Mexico; Urocyon cinereoargenteus.
