| trypanosoma cruzi infection in walker hounds from virginia. | trypanosomiasis has been reported in dogs from texas, oklahoma, louisiana, and south carolina. we describe the first isolation and characterization of trypanosoma cruzi from a walker hound pup in virginia that also had postvaccinal distemper. the mother of the pup and 7 of its 8 siblings also were found to be infected with t cruzi, suggesting that the parasite had been transmitted transplacentally or through lactation. parasitologic, serologic, histologic, and molecular methods were used to esta ... | 1995 | 8533975 |
| prevalence of antibodies to trypanosoma cruzi in raccoons (procyon lotor) from an urban area of northern virginia. | raccoons (procyon lotor) are reservoir hosts for trypanosoma cruzi. a 3-yr-long serological survey was conducted to determine the prevalence of antibodies to this zoonotic parasite in raccoons collected from fairfax county, virginia, a suburban/urban area outside washington, d.c. serum samples from 464 raccoons were examined for t. cruzi antibodies at a 1:40 dilution with an indirect fluorescent antibody test (ifat) and brazil strain t. cruzi amastigotes and trypomastigotes as antigen. a positiv ... | 2005 | 15986630 |
| seroprevalence of trypanosoma cruzi among eleven potential reservoir species from six states across the southern united states. | trypanosoma cruzi, the causative agent of chagas' disease, is a substantial public health concern in latin america. although rare in humans and domestic animals in the united states, t. cruzi is commonly detected in some wildlife species, most commonly raccoons (procyon lotor) and virginia opossums (didelphis virginiana). to increase our understanding of the reservoir host species range and geographic distribution, 11 species of mammals from six states spanning the known range of t. cruzi (arizo ... | 2010 | 20020815 |
| toxoplasma gondii and trypanosoma cruzi antibodies in dogs from virginia. | toxoplasma gondii and trypanosoma cruzi are zoonotic protozoan parasites that cause disseminated infections in many vertebrate species. the present study determined the seroprevalence of t. gondii and tr. cruzi in a population of dogs from virginia. serum samples were tested from 90 domestic dogs collected from animal shelters in virginia. using an indirect immunofluorescent antibody test, sera were examined at a 1 : 50 dilution and antibodies to t. gondii were found in 19 dogs (21%). antibodies ... | 2010 | 20500504 |
| survey of antibodies to trypanosoma cruzi and leishmania spp. in gray and red fox populations from north carolina and virginia. | 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 tes ... | 2010 | 21158642 |
| congenital transmission of chagas disease - virginia, 2010. | chagas disease, caused by infection with the parasite trypanosoma cruzi, affects 8-11 million persons globally. in the endemic areas of mexico, central america, and south america, most infections are transmitted by triatomine insect (kissing bug) vectors. however, infection also can be acquired congenitally or through blood transfusion, organ transplantation, consumption of triatomine-contaminated food or drink, or laboratory accident. early detection and treatment are highly effective; however, ... | 2012 | 22763884 |
| isolation, mouse pathogenicity, and genotyping of trypanosoma cruzi from an english cocker spaniel from virginia, usa. | trypanosoma cruzi was demonstrated in blood smears and heart tissue from a 5-year old, female, english cocker spaniel that had never been outside of the state of virginia, usa. plasma from the dog was positive in a commercially available immunochromatographic dipstick assay for t. cruzi and negative in an immunochromatographic dipstick assay for visceral leishmania spp. the plasma from the dog had an indirect immunofluorescent antibody titer of 1:800 against epimastigotes of t. cruzi while the t ... | 2012 | 22341614 |
