| prevalence of toxoplasma gondii infection in raccoons. | serum samples from 427 raccoons (93 from pennsylvania, 45 from new jersey, 72 from south carolina, 68 from virginia, 30 from iowa, and 119 from ohio) were evaluated for toxoplasma gondii antibodies in dilutions of 1:25, 1:50, and 1:500. the distribution of t gondii antibody titers was less than 1:25 for 212 raccoons (49.6%), 1:25 for 34 raccoons (7.9%), 1:50 for 117 raccoons (27.4%), and greater than or equal to 1:500 for 64 raccoons (14.9%). tissue cysts were seen in the liver, and tachyzoites ... | 1992 | 1559896 |
| toxoplasma gondii antibodies in common barn-owls (tyto alba) and pigeons (columba livia) in new jersey. | in southwestern new jersey during 1986 and 1987, common barn-owls and pigeons were captured on farmsteads and tested for toxoplasma gondii antibodies by a modified direct agglutination test. in 1986, 3/28 (10.7%) adult and 0/124 nestling owls tested positive at titers of greater than or equal to 1:40. additionally, 2/34 (5.9%) pigeons tested had t. gondii antibodies at titer of 1:320. in 1987, 9/38 (27.3%) adult and 18/80 (22.5%) nestling owls tested positive at titers of greater than or equal t ... | 1990 | 2382386 |
| neuroepidemiology of acquired immunodeficiency syndrome. | data from the centers for disease control (cdc) and from the hospitals affiliated with the university of california, san francisco show a significant incidence of neurological complications in aids patients and suggest that patients from different risk groups and geographic regions are at different relative risk for specific neurological complications. cdc national surveillance data show that haitian-born aids patients are 3.7 times more likely to have neurological complications than are patient ... | 1988 | 3216295 |
| acute fatal toxoplasmosis in squirrels. | two dead gray squirrels submitted to the northeastern research center for wildlife diseases ahd nonsuppurative encephalitis and interstitial pneumonitis, with toxoplasma gondii cysts and tachyzoites in many tissues. these infections have rarely been reported from gray squirrels but could mimic clinical rabies. | 1981 | 7327992 |
| prevalence of agglutinating antibodies to neospora caninum in raccoons, procyon lotor. | neospora caninum is an apicomplexan parasite that causes neonatal neuromuscular disease in dogs and abortions in cattle. dogs are the only proven definitive host. little is known about the prevalence of antibodies to this parasite in wildlife. sera from 99 raccoons (procyon lotor) were examined for agglutinating antibodies to n. caninum using the modified agglutination test employing formalin-fixed tachyzoites as antigen. raccoons originated in florida (n = 24, collected in 1996), new jersey (n ... | 2001 | 11695399 |
| occurrence, isolation, and genetic characterization of toxoplasma gondii from white-tailed deer (odocoileus virginianus) in new jersey. | the ingestion of uncooked infected white-tailed deer (wtd) tissues can transmit toxoplasma gondii infection to humans and mesocarnivores, including cats. in the present study, we tested 264 wtd from new jersey for t. gondii infection during the 2011-2012 hunting season. serum samples were tested for antibodies to t. gondii by the modified agglutination test (cutoff titer, 25); 76 (28.7%) of 264 wtd were seropositive. heart muscle samples from 64 seropositive wtd were digested in pepsin, and the ... | 2013 | 23574007 |
