- Surveillance for Antibodies to Leishmania spp. in Dogs From Sri LankaRosypal, A. C.; Tripp, S.; Kinlaw, C.; Hailemariam, S.; Tidwell, R. R.; Lindsay, David S.; Rajapakse, Rpvj; Sreekumar, C.; Dubey, Jitender P. (American Society of Parasitology, 2010-02)The global distribution of leishmaniasis is rapidly expanding into new geographic regions. Dogs are the primary reservoir hosts for human visceral leishmaniasis caused by infection with Leishmania infantum. Natural infections with other Leishmania spp. can occur in dogs, but their role as reservoir hosts for other species of Leishmania is uncertain. Leishmania donovani is traditionally considered a visceralizing anthroponotic species; however, cutaneous leishmaniasis caused by L. donovani has been reported 111 Sri Lanka. In the present study, sera from 114 dogs in Sri Lanka were examined for antibodies to visceralizing Leishmania spp. Sera were tested by the canine immunochromatographic strip assays based on recombinant K39 antigen. Anti-Leishmania spp. antibodies were detectable in 1 of 114 (0.9%) dogs from Sri Lanka. Nonetheless, serological evidence suggests that leishmaniasis may be an emerging zoonosis in Sri Lanka.
- Survey of Antibodies to Trypanosoma cruzi and Leishmania spp. in Gray and Red Fox Populations From North Carolina and VirginiaRosypal, A. C.; Tripp, S.; Lewis, S.; Francis, J.; Stoskopf, M. K.; Larsen, R. S.; Lindsay, David S. (American Society of Parasitology, 2010-12)American trypanosomiasis and leishmaniasis are caused by related hemoflagellate parasites, Trypanosoma cruzi and Leishmania spp., which share several common host species. Both zoonotic protozoans are endemic in the United States. Canines, including domestic and wild canids, are reservoir hosts for human infections with T cruzi and Leishmania spp. The present study examined the seroprevalence of T. cruzi and Leishmania spp. in wild canids from North Carolina and Virginia. Wild canine species tested in this work included 49 gray foxes (Urocyon cinereoargenteus) and 5 red foxes (Vulpes vulpes). Overall, sera samples from 54 foxes (North Carolina = 43; Virginia = 11) were tested by immunochromatographic strip assays (ICT). Antibodies to T cruzi were found in 4 (9%) gray foxes from North Carolina and 2 (18%) gray foxes from Virginia. Antibodies to Leishmania spp. were detected in 1 (2%) gray fox from North Carolina. Our results indicate that wild canids are exposed more frequently to T cruzi in North Carolina than Leishmania spp. and only T cruzi in Virginia.
