| 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 |

| 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 |
| 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 |
| 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 in wild raccoons, opossums, and triatomine bugs in southeast georgia, u.s.a. | the prevalence of trypanosoma cruzi infection among wild opossums and raccoons live-trapped in 6 southeast georgia counties was determined. epimastigotes typical of t. cruzi were observed in liver infusion tryptose medium cultures of blood from 6 of 39 opossums (15.4%) and 12 of 54 raccoons (22.2%). trypomastigotes (6,000/ml) were observed in a wet mount of blood from 1 of the animals, a raccoon trapped on st. catherines island in liberty county. in addition, t. cruzi parasites were observed in ... | 1995 | 7707220 |
| occurrence of antibody to trypanosoma cruzi in dogs in the southeastern united states. | seven of 365 dogs from georgia and other southeastern states were seropositive for antibody to trypanosoma cruzi by the complement-fixation (cf) test. sera from 24 dogs, including the 7 dogs seropositive by cf test, were reactive at dilutions of 1:128 or 1:256 by the direct-agglutination (da) test. dogs with positive cf titers were significantly (p less than 0.05) younger than were the dogs in the total population surveyed. the occurrence of antibody to t cruzi was similar, regardless of the dog ... | 1981 | 7027850 |
| low prevalence of chagas parasite infection in a nonhuman primate colony in louisiana. | chagas disease, an important cause of heart disease in latin america, is caused by the parasite trypanosoma cruzi, which typically is transmitted to humans by triatomine insects. although autochthonous transmission of the chagas parasite to humans is rare in the united states, triatomines are common, and more than 20 species of mammals are infected with the chagas parasite in the southern united states. chagas disease has also been detected in colonies of nonhuman primates (nhp) in georgia and t ... | 2012 | 23043809 |
| parasitology, virology, and serology of free-ranging coyotes (canis latrans) from central georgia, usa. | we examined 31 free-ranging coyotes (canis latrans) from central georgia, usa, for select parasites and viral agents. sixteen coyotes had adult heartworms (dirofilaria immitis). serum samples from 27 animals revealed antibodies against canine parvovirus (100%), canine distemper virus (48%), canine adenovirus (37%), and trypanosoma cruzi (7%); none were detected against leishmania spp. twenty-two of 24 (92%) coyotes were positive for toxoplasma gondii. real-time pcr of feces revealed 32% of coyot ... | 2014 | 25098300 |
| virulence and vertical transmission of two genotypically and geographically diverse isolates of trypanosoma cruzi in mice. | although principally considered a vector-borne disease, the vertical transmission of trypanosoma cruzi from mother to child is now recognized as a significant and increasing threat to human health. despite its importance, significant gaps exist in our understanding of the relationships between genotype, virulence, and the extent of vertical transmission of this pathogen. to better understand these relationships, we describe the comparison of a south american-derived type i isolate (bs) of t. cru ... | 2010 | 19954258 |
| trypanosoma cruzi prevalence and epidemiologic trends in lemurs on st. catherines island, georgia. | lemurs on st. catherines island, georgia were tested for trypanosoma cruzi infection to develop a better understanding of the epizootiology of the parasite in nonhuman primates in the southeastern united states. fifty-six ring-tailed (lemur catta), blue-eyed black (eulemur macaco flavifrons), and black-and-white ruffed (varecia variegata variegata) lemurs were tested by hemoculture and serology to determine the prevalence of t. cruzi in the population. of those tested 3 (5%) were identified as c ... | 2007 | 17436947 |

| genotype diversity of trypanosoma cruzi in small rodents and triatoma sanguisuga from a rural area in new orleans, louisiana. | chagas disease is an anthropozoonosis caused by the protozoan parasite trypanosoma cruzi that represents a major public health problem in latin america. although the united states is defined as non-endemic for chagas disease due to the rarity of human cases, the presence of t. cruzi has now been amply demonstrated as enzootic in different regions of the south of the country from georgia to california. in southeastern louisiana, a high t. cruzi infection rate has been demonstrated in triatoma san ... | 2015 | 25890064 |
