“…The seroprevalence of T. gondii infection in donkeys is frequently high, including seropositivity rates of 45% [17] and 65.6% [18] in Egypt, 43.2% in Brazil [19], 34% in Spain [20], 20.3% [21] and 23.6% [22] in China, from 5 to 8% in Italy [23], and 6.4% in the United States of America [24]. Additionally, milk was found to be positive for T. gondii antibodies in 46.3% of pregnant jennies [17].…”

BackgroundToxoplasma gondii is a worldwide zoonotic protozoan. Consumption of raw milk from infected animals is considered a risk factor for acquiring toxoplasmosis in humans. Recently, donkey milk has been indicated for therapeutic and nutritional purposes and T. gondii infection is common in donkeys. The purpose of the present paper was to detect the presence of parasite DNA in milk of T. gondii positive donkeys.FindingsAntibodies to T. gondii were found in 11 out of 44 healthy lactating donkeys by IFAT. T. gondii DNA was detected by PCR in blood of 6 and milk of 3 seropositive jennies. Results of limited RFLP-PCR genotyping indicated the presence of T. gondii genotype II or III, commonly found in Europe.ConclusionsThe occurrence of T. gondii DNA in milk suggests that the consumption of raw milk from seropositive donkeys could be a potential source of human infection.

“…Worldwide seroprevalence of T. gondii infection in horses has been summarised prior to 2010 by Dubey, ranging from 0.4% to 48.1% [8]; and since then, it has been reported to be 24% in the Czech Republic by LAT [15], 32% in Riyadh Province, Saudi Arabia by DT [16], 34.0% in Costa Rica by MAT [17], 69.6% in the Fernando de Noronha, Brazil by MAT [18], and 10.8% in Southern Spain by MAT [19]. Worldwide seroprevalence of T. gondii infection in donkeys was reported as 65.6% in Egypt by ELISA [8], 11.0% in Gemlik, Turkey by LAT [8], 25.6% in Southern Spain by MAT [19], and 43.2% in Northeast of Brazil by indirect immunofluorescence reaction (IFI ) [20]. …”

BackgroundToxoplasma gondii is an important zoonotic pathogen infecting humans and almost all warm-blooded animals. The most common sources of human infection are ingestion of tissue cysts in raw or undercooked meat. However, limited information is available about T. gondii infection in horses and donkeys in China. In the present study, we report the seroprevalence of T. gondii infection in horses and donkeys in Liaoning province, northeastern China.MethodsSerum samples were collected from 711 and 738 slaughtered horses and donkeys, respectively, in 13 regions of Liaoning province. The modified agglutination test (MAT) was used to test the specific antibodies to T. gondii.ResultsIn this study, 178 of 711 (25.0%) horses were seropositive for T. gondii with titers of 1:25 in 81, 1:50 in 62, 1:100 in 33, and 1:200 in 2, and seroprevalence of T. gondii infection from 13 regions ranged from 8.2% to 37.0%. Antibodies to T. gondii were found in 174 of 738 (23.6%) donkeys with titers of 1:25 in 66, 1:50 in 54, 1:100 in 49, and 1:200 in 5, and seroprevalence varied in 13 different regions, ranging from 9.1% to 32.6%.ConclusionsThe results of the present study indicated that the rate of infection with T. gondii in horses and donkeys is a little high in Liaoning province, northeastern China in comparison to other surveys in China, which suggests that consumption of horse and donkey meat in this area may represent a potential source for human infection with T. gondii.

RESUMO.-Este estudo teve como objetivo determinar a soroprevalência da toxoplasmose em equídeos mantidos em diferentes formas de manejo no estado de Pernambuco. Para tanto, um total de 400 amostras de soro sanguíneo de equídeos clinicamente saudáveis foram analisados através do teste de aglutinação modificado (MAT) considerando-se cut-off de 1:25. Dados referentes às características dos animais e dos rebanhos, sistema de criação, presença de outros animais, idade, sexo, raça, aptidão, condição física foram coletados por meio de questionários investigativos. Anticorpos IgG anti-Toxoplasma gondii foram detectados em 12,5% (50/400) dos animais analisados. Dos 12 municípios estudados, houve positividade em 91,67% (11/12) com variação entre 4,4% e 33,3%. Quando avaliados os fatores de risco, apenas o fator mesorregião (p=0,029) apresentou associação com a infecção, particularmente Zona da Mata (OR=3), seguida de Região Metropolitana do Recife (OR=2,2), Agreste (OR=1,7) e Sertão (OR=1). Os resultados revelam a presença do parasito na área estudada, o que pode representar um elo na cadeia de transmissão da toxoplasmose a qual tem repercussão em saúde pública tendo em vista que o Brasil é o oitavo maior exportador de carne equina do mundo. This paper reports seroprevalence of toxoplasmosis in horses kept in different forms of breeding system in the state of Pernambuco. For that, 400 blood serum samples from clinically healthy horses were analyzed through the test of modified agglutination (MAT) considering cut-off of 1:25. Data related to the characteristics of the animals and herds, breeding system, presence of other animals, age, gender, breed, aptitude, and physical conditions were collected throughout investigative surveys. IgG anti-Toxoplasma gondii antibodies were detected in 12.5% (50/400) of the analyzed animals. In the 12 studied towns, there was a positivity in 91. 67% (11/12) with a variation between 4% and 33.3%. When the risk factors were evaluated, only the mesoregion factor (p=0.029) had an association with the infection, particularly the Zona da Mata region (OR=3), followed by the Recife Metropolitan Area (OR=2.2), Agreste region (OR=1.7) and Sertão region (OR=1). The results shows the presence of the parasites on the studied area, which may represent a link with the transmission chain of toxoplasmosis which has influence on the public health system, considering that Brazil is the eighth greatest exporter of equine meat in the world.
