          Abstract

          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 antibodies were detected in leopards ( Panthera pardus), wild geese ( Anser cygnoides), and Eastern grey kangaroos ( Macropus giganteus) . Domestic species from 13 counties of Jiangxi Province, China were also investigated by an indirect hemagglutination (IHA) test. Thirty-five of 340 goats (10%), 94 of 560 water buffaloes (17%), and 4 of 35 cattle (11%) were found to be seropositive. This is the first report of T. gondii infection in animals kept in zoos and domestic animals in this province.

          Toxoplasma gondii est un protozoaire parasite zoonotique qui infecte une large gamme d’animaux à sang chaud à travers le monde. Dans la présente étude, les anticorps dirigés contre T. gondii ont été déterminés en utilisant un test commercial d’hémagglutination indirecte (IHA) chez des animaux sauvages gardés dans un zoo. Trois (27 %) parmi 11 girafes ( Giraffa camelopardalis), 1 (20 %) parmi 5 loups ( Canis lupus laniger), 1 (17 %) parmi 6 hippopotames ( Hippopotamus amphibious) et 2 (22 %) parmi 9 cygnes siffleurs ( Cygnus columbianus) ont été trouvés positifs. Aucun anticorps n’a été détecté chez des léopards ( Panthera pardus), des oies sauvages ( Anser cygnoides) et des kangourous ( Macropus giganteus). Les espèces domestiques provenant de 13 comtés de la province de Jiangxi, en Chine, ont également fait l’objet d’une enquête par hémagglutination indirecte. Trente-cinq chèvres parmi 340 (10 %), 94 buffles d’eau parmi 560 (17 %) et 4 bovins parmi 35 (11 %) ont été retrouvés séropositifs. Ceci est le premier rapport sur l’infection par T. gondii chez les animaux gardés dans des zoos et les animaux domestiques de cette province.

          Seroprevalence of Toxoplasma gondii infection in yaks (Bos grunniens) on the Qinghai-Tibetan Plateau of China.

          Toxoplasma gondii (T. gondii), a zoonotic parasite infects almost all warm-blooded animals and causes significant economic losses. To date, however, it is still unclear whether yaks from the Qinghai-Tibetan plateau of China are exposed to T. gondii. On the present study, a survey was conducted for the first time, to investigate the seroprevalence of T. gondii infection in yaks (Bos grunniens) on the Qinghai-Tibetan Plateau (Qinghai, Tibet, Hongyuan area of Sichuan province). A total of 905 and 736 serum samples were collected from yaks in these areas in 2012 and 2013, respectively and assayed for T. gondii antibodies by an indirect hemagglutination test (IHA). The results showed that seroprevalence on plateau was 21.7% and 29.1% in 2012 and 2013, respectively with the prevalence of 22.4%, 19.4% and 25.5% in 2012 for Qinghai, Tibet and Hongyuan of Sichuan, respectively and of 26.4%, 27.0% and 33.7% for these three regions in 2013, respectively. The present survey indicated that the infection with T. gondii in yaks was widely spread in recent years on the plateau causing a high risk factor for animals and humans.

            Seroprevalence of Toxoplasma gondii in goats in Hunan province, China

            Toxoplasma gondii infections are prevalent in animals and humans worldwide. In the present investigation, the seroprevalence of T. gondii in goats was investigated in Hunan province, subtropical China between March 2014 and December 2015. A total of 1,028 serum samples collected from 14 administrative regions of Hunan province were evaluated by the indirect hemagglutination test (IHAT) for the detection of specific antibodies. Antibodies to T. gondii were detected in 124 serum samples (12%). The T. gondii seroprevalence ranged from 1.7% to 19% among different regions in subtropical China, and the differences were statistically significant (p < 0.01). The results of the present survey indicated that T. gondii infection is prevalent in goats in Hunan, which poses a potential risk for human infection with T. gondii in this province.

              Prevalence of antibodies to Toxoplasma gondii in the sera of rare wildlife in the Shanghai Zoological Garden, People's Republic of China.

              The prevalence of antibodies to Toxoplasma gondii in the sera of rare wildlife in the Shanghai Zoological Garden, PR China, was examined using a modified agglutination test (MAT) and an enzyme-linked immunosorbent assay (ELISA). Forty-one (35%) of 117 animals belonging to two classes, 10 orders, 18 families, 37 genera and 52 species (including sub-species) were sero-positive for MAT. By MAT, T. gondii antibodies were found in 11.1% (4/36) of birds, in 25% (4/16) of primates, in 69.4% (25/36) of carnivores and in 27.6% (8/29) of herbivores. Thirty-three (33.7%) of 98 animals tested by protein A ELISA were sero-positive. By ELISA, T. gondii antibodies were found in none of 36 birds, in 33.3% (4/12) of primates, in 87.1% (27/31) of carnivores and in 10.5% (2/19) of herbivores.
