prevalence of toxoplasma gondii antibody in wild enzyme-linked immunosorbent assay (elisa) was developed to measure total antibody to toxoplasma gondii in serum samples from macropods. the validity of the assay was established by comparing parasite isolation in mice for 17 tasmanian pademelons (thylogale billardierii) and 17 bennett's wallabies (macropus rufogriseus rufogriseus). the elisa was then used to detect antibody against t. gondii in serum from 236 macropods, collected from 21 locations in tasmania, including flinders island. antib ...19883421883
toxoplasmosis in captive bennett's wallabies (macropus rufogriseus) in argentina.wallabies and other australian marsupials are among the most susceptible species to toxoplasma gondii. fatal generalized toxoplasmosis was diagnosed in two captive 3 year-old female bennett's wallabies (macropus rufogriseus) from argentina (w 1 and w 2) with a history of sudden death. both animals had internal joeys which died 2 days after their mothers. serologically, both females and one adult male without clinical signs from the same enclosure (w 3) had antibody titers for t. gondii>or=800 by ...200717056183
toxoplasmosis in wallabies (macropus rufogriseus and macropus eugenii): blindness, treatment with atovaquone, and isolation of toxoplasma gondii.australasian marsupials, especially wallabies, are highly susceptible to clinical toxoplasmosis. this paper describes the use of atovaquone for effective treatment of toxoplasmosis in 4 bennett's wallabies (macropus rufogriseus), along with the serology, isolation of toxoplasma gondii, and genotyping of 3 t. gondii isolates from 5 captive wallabies. this is the first report of success in treating acute toxoplasmosis in wallabies, the first report of serology followed over a significant period of ...200818576797
seroepidemiology of toxoplasma gondii in zoo animals in selected zoos in the midwestern united states.toxoplasma gondii infections in zoo animals are of interest because many captive animals die of clinical toxoplasmosis and because of the potential risk of exposure of children and elderly to t. gondii oocysts excreted by cats in the zoos. seroprevalence of t. gondii antibodies in wild zoo felids, highly susceptible zoo species, and feral cats from 8 zoos of the midwestern united states was determined by using the modified agglutination test (mat). a titer of 1:25 was considered indicative of t. ...200818605803
toxoplasma gondii inclusions in peripheral blood leukocytes of a red-necked wallaby (macropus rufogriseus).a 2-year-old, male, red-necked (bennett's) wallaby (macropus rufogriseus) from a zoological facility was presented for peracute onset of severe depression, unresponsiveness, ataxia, and loose feces. serum biochemical abnormalities included azotemia, hypoalbuminemia, increased alanine aminotransferase activity, hyperbilirubinemia, hyperphosphatemia, and hyperkalemia, consistent with multi-organ system failure. severe thrombocytopenia suggested possible disseminated intravascular coagulation. peri ...200717311203
toxoplasmosis in bennett's wallabies (macropus rufogriseus) in spain.toxoplasmosis is one of the more common parasitic zoonoses world-wide. in this study, an epizootic of toxoplasmosis among captive bennett's wallabies (macropus rufogriseus) from different locations is reported. by means of light microscopy, toxoplasma gondii-like tachyzoites were observed associated to interstitial pneumonia, non-suppurative myocarditis, cholangiohepatitis and severe gastroenteritis. the protozoa stained positively with a t. gondii antibody and ultrastructurally were similar to ...200919046816
fatal toxoplasmosis associated with an atypical toxoplasma gondii strain in a bennett's wallaby (macropus rufogriseus) in spain.toxoplasmosis is often fatal in captive wallabies, but the causes of this high susceptibility are not well understood. here, we report fatal toxoplasmosis in a bennet's wallaby (macropus rufogriseus) due to an atypical toxoplasma gondii strain for the first time in europe. the wallaby was from a colony of 7 bennet's wallabies that died over a 17-month period at a safari-zoological park in northeastern spain. only one of these wallabies was examined at necropsy. t. gondii-like organisms were dete ...201323523164
presumptive acute neural toxoplasmosis in a captive red-necked wallaby (macropus rufogriseus).a red-necked male wallaby (macropus rufogriseus) from a german zoo was presented for acute onset of severe neurological signs, including head tremor, lethargy, unresponsiveness, and weakness. serum biochemical abnormalities included increased ldh- and ast-levels, hyperproteinaemia, and reduced alt-, alp-, and creatinine-levels. the wallaby was found serologically positive for toxoplasma gondii by the indirect haemagglutination test. after initiation of therapy by subcutaneous injections of trime ...201020613947
serodiagnosis of acute toxoplasmosis in macropods.the sera of 34 australian macropods, the brains of which had been bioassayed for toxoplasma gondii, were used to establish that a titre greater than 1/32 was significant for a direct agglutination test against toxoplasmosis. in addition, the concentration of 2-mercaptoethanol required to destroy the igm fraction of macropod serum was confirmed in a modified direct agglutination test. to further validate the tests, the serological responses of three eastern grey kangaroos (macropus giganteus) dos ...19892588468
