| prevalence of antibodies to toxoplasma gondii in wild mammals of missouri and east central kansas: biologic and ecologic considerations of transmission. | sera from 273 wild mammals from missouri and kansas (usa), collected between december 1974 and december 1987, were tested for the presence of antibodies to toxoplasma gondii using the sabin-feldman dye test. sixty-five (24%) had antibodies at titers of > or = 1:8, including 38 (66%) of 58 carnivores, 14 (15%) of 94 omnivores, 13 (11%) of 117 herbivores, and none of four insectivores. the prevalence of antibodies in mice (mus musculus and peromyscus spp.) and rats (rattus norvegicus and sigmodon ... | 1995 | 7563419 |
| seroprevalence of and risk factors for toxoplasma gondii in the us swine herd using sera collected during the national animal health monitoring survey (swine 2006). | the united states department of agriculture (usda) initiated the national animal health monitoring system (nahms) in 1983 to collect, analyse and disseminate data on animal health, management and productivity in us domestic livestock populations, including swine. the programme includes an on-farm serological sampling component which can be used to monitor seroprevalence of various pathogens, including toxoplasma gondii. the purpose of this study was to determine the seroprevalence of t. gondii i ... | 2010 | 19744304 |
| evidence of toxoplasma gondii exposure in boer goat herds in missouri, usa. | limited data currently exist on the prevalence of toxoplasma infections in goats in the usa. the objective of this pilot investigation was to determine the prevalence of toxoplasma gondii antibodies in boer goats raised in missouri. sera collected from 367 boer goats in 24 herds were tested using a commercial latex agglutination assay. evidence of t. gondii antibodies was present in 25 of the 367 goats, with titres of 1 : 32 in 4, 1 : 64 in 11, 1 : 128 in 5, 1 : 256 in 3 and 1 : 1024 in 2. estim ... | 2014 | 24256548 |
