| characterization of toxoplasma gondii from raccoons (procyon lotor), coyotes (canis latrans), and striped skunks (mephitis mephitis) in wisconsin identified several atypical genotypes. | during 2005-2006, sera and tissues from raccoons (procyon lotor), coyotes (canis latrans), and skunks (mephitis mephitis) from the state of wisconsin were tested for toxoplasma gondii infection. antibodies to t. gondii were found in 32 of 54 (59.2%) raccoons, 18 of 35 (51.4%) coyotes, and 5 of 7 (71.4%) skunks using the modified agglutination test and a cut-off titer of 1:20. pooled tissues (brains, hearts, and tongues) from 30 raccoons, 15 coyotes, and 1 skunk were bioassayed for t. gondii infe ... | 2007 | 18314705 |
| a sero-survey of toxoplasmosis in farm and non-farm children from wisconsin, united states, 1997-1999. | toxoplasmosis is among the most widespread and prevalent zoonosis in the world. people can become infected through ingestion of oocysts shed by felids or of tissue cysts contained in meat from infected animals. acute infection can result in a wide spectrum of consequences, including flu-like illness and retinitis, as well as congenital infection in pregnant women. severe disease can occur, especially if people are immunocompromised. frequency of human infection varies substantially by region due ... | 2013 | 24025220 |
| an outbreak of toxoplasmosis in farmed mink (mustela vison s.). | a large wisconsin mink (mustela vison) farm experienced an outbreak of toxoplasmosis in the spring of 1999 following an outbreak of canine distemper during the previous fall. major clinical signs for pregnant females included reduced feed consumption, abortions, and stillborn kits; kits < or =3 weeks old experienced ataxia and mortality. of 7,800 females, 1,976 (26%) lost their entire litter either from abortion or neonatal mortality. kit mortality from 7 days to 3 weeks of age was 3,300, and ov ... | 2001 | 11482603 |
| 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 |
