| toxoplasma gondii antibodies in naturally exposed wild coyotes, red foxes, and gray foxes and serologic diagnosis of toxoplasmosis in red foxes fed t. gondii oocysts and tissue cysts. | antibodies to toxoplasma gondii were determined in sera from 222 coyotes (canis latrans), 283 red foxes (vulpes vulpes), and 97 gray foxes (urocyon cinereoargenteus) from indiana, kentucky, michigan, and ohio during 1990-1993. sera were examined in 1:25, 1:100, and 1:500 dilutions by the modified direct agglutination test (mat) with formalinized whole tachyzoites plus mercaptoethanol. antibodies were found in 131 (59.0%) of 222 coyotes, 243 (85.9%) of 283 red foxes, and 73 (75.3%) of 97 gray fox ... | 1999 | 10219302 |
| high seroprevalence of toxoplasma gondii in elk (cervus canadensis) of the central appalachians, usa. | toxoplasma gondii is an important protozoan parasite of mammals that impacts animal health and behavior. although this parasite has been documented in several cervid species, including red deer (cervus elaphus) in europe, little is known about t. gondii impacts on the closely related north american counterpart, the elk (wapiti, cervus canadensis), which has increased in number and expanded in range during the past century. we assessed seroprevalence of t. gondii antibodies using a modified agglu ... | 2017 | 28130658 |
| prevalence of toxoplasma gondii antibodies in nine populations of dairy goats: compared titers using modified direct agglutination and indirect hemagglutination. | in a convenience survey of dairy goats on 9 farms in tennessee, kentucky, and georgia, 54 of 99 females were positive for antibodies to toxoplasma gondii as measured by the indirect hemagglutination test (iha). two of 9 males were also positive. positive goats were found on all farms. the percentage of positive does increased from 55% to 65% when the sera were titered a second time by modified direct agglutination (mdat). this difference was not statistically significant, indicating that both ih ... | 1990 | 2299530 |
| toxoplasma gondii infections in captive black-footed ferrets (mustela nigripes), 1992-1998: clinical signs, serology, pathology, and prevention. | an epizootic of toxoplasmosis occurred among 22 adult and 30 kit black-footed ferrets (mustela nigripes) maintained under quarantine conditions at the louisville zoological garden (louisville, kentucky, usa) in june, 1992. black-footed ferrets appear to be highly susceptible to acute and chronic toxoplasmosis. clinical signs were observed in 19 adults and six kits and included anorexia, lethargy, corneal edema, and ataxia. two adults and six kits died with acute disease. high antibody titers to ... | 2003 | 14733273 |
