| trypanosomiasis in raccoons from georgia. | trypanosoma cruzi frequently infects wild mammals in the southern united states but little is known about the effect of the parasite on reservoir hosts such as the raccoon (procyon lotor). to investigate this issue, 30 raccoons trapped on st. catherine's island (georgia, usa) during september, 1994 were tested for t. cruzi infection by examination of wet mounts of fresh blood and by culturing blood in liver infusion tryptose medium. thirteen animals (43%) were found to be infected with t. cruzi. ... | 1998 | 9476234 |
| trypanosoma cruzi infection of free-ranging lion-tailed macaques (macaca silenus) and ring-tailed lemurs (lemur catta) on st. catherine's island, georgia, usa. | free-ranging old world primates released on st. catherine's island, georgia (usa), were tested for infection with trypanosoma cruzi as part of a study of the epizootiology of sylvatic t. cruzi in the southeastern usa. the parasite was observed in liver infusion tryptose medium cultures of blood from seven of 11 lion-tailed macaques (macaca silenus) and one of 19 ring-tailed lemurs (lemur catta). cultures of blood from 10 black and white ruffed lemurs (varecia variegata) were all negative. analys ... | 1998 | 9638621 |
| comparison of serological methods and blood culture for detection of trypanosoma cruzi infection in raccoons (procyon lotor). | the indirect immunofluorescent antibody test (ifat) and enzyme-linked immunosorbent assay (elisa) were compared with blood culture for the detection of trypanosoma cruzi infection in 83 raccoons (procyon lotor) trapped in 4 counties of southeast georgia. both ifat and elisa detected 24 of 25 culture-positive samples (96% sensitivity). cultures from 25 raccoons (30%) were positive for epimastigotes, whereas a total of 50 raccoons (60%) was seropositive by either the ifat or elisa. forty-five of 8 ... | 2001 | 11695383 |
| seroprevalence of trypanosoma cruzi in raccoons from south carolina and georgia. | trypanosoma cruzi, the causative agent of american trypanosomiasis or chagas' disease, is of both medical and veterinary importance as is evidenced by chronic phase myocarditis in humans and dogs. further, t. cruzi has been reported from over 20 species of wildlife reservoir hosts in the usa, with raccoons (procyon lotor) and opossums (didelphis virginiana) being the most common. whereas previous studies on t. cruzi in raccoons have included only culture and direct examination of blood, the indi ... | 2002 | 11838232 |
| 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 |
