| tazonomy of toxoplasma. | after reviewing reports of the hosts, structure and life cycle of toxoplasma, the genus is placed in the apicomplexan family eimeriidae and the folllowing 7 species are recognized: toxoplasma gondii (nicolle & manceaux) (type species) from about 200 species of mammals and birds, with oocysts in felids; toxoplasma alencari (da costa & pereira) from the frog leptodactylus ocellatus; toxoplasma brumpti coutelen from the iguana iguana tuberculata; toxoplasma colubri tibaldi from the snakes coluber m ... | 1977 | 325203 |
| shedding of toxoplasma gondii oocysts by felidae in zoos in the czech republic. | in 1995 and 1996, the shedding of toxoplasma gondii oocysts was monitored in the faeces of felidae in six zoos in the czech republic. in all, 2287 samples of faeces from 19 species of felidae were examined. in ostrava zoo, four episodes of shedding of toxoplasma-like oocysts were identified, using a flotation examination, in a pair of wild cats (felis silvestris), six episodes in a wild cat held separately, and three episodes in a pair of amur leopard cats (f. euptilurus). after the passage of s ... | 1998 | 9493305 |
| toxoplasma gondii antibodies in exotic wild felids from brazilian zoos. | serum samples from 37 captive exotic felids in 12 zoos from six brazilian states were assayed for antibodies to toxoplasma gondii by the modified agglutination test using formalin-fixed whole tachyzoites. titers greater than or equal to 1:20 were considered positive. antibodies to t. gondii were found in 24 of 37 (64.9%) felids, including one european lynx (lynx lynx), two jungle cats (felis chaus), two servals (leptailurus serval), two tigers (panthera tigris), three leopards (panthera pardus), ... | 2001 | 12785684 |
| detection of toxolasma gondii in captive wild felids. | toxoplasma gondii can infect all species of warm-blooded animals, including humans, and causes serious diseases in immunocompromized hosts. live tachyzoites derived from serial passage in hela culture were used in the sabin-feldman dye test for detection of toxoplasma gondii antibody in serum samples of 21 captive wild felids including one fishing cat (prion nailurus viverrina), one leopard (panthera pardus), two flat-headed cats (prion nailurus planiceps), 6 tigers (panthera tigris), two leopar ... | 2006 | 17547043 |
| do free-ranging common brushtail possums (trichosurus vulpecula) play a role in the transmission of toxoplasma gondii within a zoo environment? | to investigate the possible role of common brushtail possums (trichosurus vulpecula) in the transmission of toxoplasma gondii within a zoo environment, a serological survey of a free-ranging population resident within taronga zoo, sydney, australia was undertaken using the modified agglutination test (mat). for comparison, the seroprevalence of t. gondii antibodies was also assessed in a possum population inhabiting a felid-free, non-urban woodland habitat. six of 126 possums (4.8%) from the zoo ... | 2008 | 18281157 |
| 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. ... | 2008 | 18605803 |
| toxoplasmosis may lead to road kills of persian leopards ( panthera pardus saxicolor) in golestan national park, iran. | three persian leopards ( panthera pardus saxicolor) that died from car accidents in golestan national park, iran, were tested for toxoplasma gondii and rabies virus infection. acute t. gondii infection was diagnosed in two persian leopards; no rabies virus was detected. acute toxoplasmosis may be a factor in persian leopard road kills. | 2016 | 26981691 |
| seroprevalence of toxoplasma gondii infection in zoo and domestic animals in jiangxi province, china. | toxoplasma gondii is a zoonotic protozoan parasite that infects a wide range of warm-blooded animals throughout the world. in the present study, antibodies to t. gondii were determined using a commercial indirect hemagglutination (iha) test in wild animals in a zoo. three of 11 giraffes (giraffa camelopardalis) (27%), 1 of 5 wolves (canis lupus laniger) (20%), 1 of 6 hippopotamuses (hippopotamus amphibious) (17%), and 2 of 9 tundra swans (cygnus columbianus) (22%) were found to be positive. no a ... | 2017 | 28224883 |
| morbid attraction to leopard urine in toxoplasma-infected chimpanzees. | parasites are sometimes capable of inducing phenotypic changes in their hosts to improve transmission [1]. toxoplasma gondii, a protozoan that infects a broad range of warm-blooded species, is one example that supports the so-called 'parasite manipulation hypothesis': it induces modifications in rodents' olfactory preferences, converting an innate aversion for cat odor into attraction and probably favoring trophic transmission to feline species, its only definitive hosts [2]. in humans, t. gondi ... | 2016 | 26859275 |
| seroprevalence of toxoplasma gondii infection in captive mammals in three zoos in mexico city, mexico. | antibodies to toxoplasma gondii were determined in 167 mammals in three zoos in mexico city, mexico, using the modified agglutination test (mat). overall, antibodies to t. gondii were found in 89 (53.3%) of the 167 animals tested. antibodies were found in 35 of 43 wild felidae: 2 of 2 bobcats (lynx rufus); 4 of 4 cougars (puma concolor); 10 of 13 jaguars (panthera onca); 5 of 5 leopards (panthera pardus); 7 of 7 lions (panthera leo); 2 of 3 tigers (panthera tigris); 2 of 3 ocelots (leopardus par ... | 2013 | 24063119 |
