“…Similar results were described by others, who also verified that goats over one yearold presented a higher percentage of seropositivity in relation to those aged less than 12 months-old 11,22 . Analysis confirmed that seropositivity was directly related to age 14 and the age factor was significant for the occurrence of infection by T. gondii in goats aged over 24 9 and 36 months-old 27 . Given the time required to achieve subsistence goat breeding in the State of Alagoas, it is probable that The authors declare that there is no conflict of interest.…”

“…Moreover, according to some authors 14 , goats maintained in suburban areas under precarious conditions of hygiene and in contact with people and their domestic animals are factors that can explain the increase in seropositivity of the herd.…”

“…As demonstrated by several studies, the principal risk factors for infection by T. gondii in goats are: sex and age, in which the principal affected group is adult females; the pluviometric index, high humidity and mild temperatures in the regions where the herds are raised 9,11 ; management systems 13 ; common feeders and drinkers for young and adult goats; the presence of cats; and goats with reproductive disorders on the property in question 4,14,15 .…”

Introduction: Goats are considered very susceptible to infection by Toxoplasma gondii and when this occurs during pregnancy, it may cause fetal death with subsequent fetal resorption, abortion, mummification, stillborn or the birth of weak goats. The objective of this work was to determine the occurrence of and identify risk factors for T. gondii infection in goats in different mesoregions in the State of Alagoas. Methods: The research was conducted on 24 goat breeding farms in 10 municipalities. A total of 454 blood samples were examined for anti-T. gondii antibodies by indirect immunofluorescence antibody test. To evaluate the risk factors of toxoplasmosis in goats, questionnaires were applied analyzing the farm's production system and nutritional, reproductive and sanitary management. Results: Disease occurrence was 39% with 95.8% of farms presenting seropositive animals. Significant associations were observed for mesoregion (OR = 0.23; 95%CI = 0.09 -0.57), age (OR = 0.36; 95%CI = 0.20 -0.64), semi-intensive herd management (OR = 8.70; 95%CI = 1.87 -40.43), access of cats to water provided for goats (OR = 3.38; 95%CI = 1.89-6.02) and cats feeding on placental remnants (OR = 2.73; 95%CI = 1.38 -5.40). Conclusions: Toxoplasma gondii infection is disseminated in the State of Alagoas and the adoption of a program that monitors infection foci is required to reduce the risk factors identified in the present study.

“…As freqüências percentuais de positividade observadas nos capris estudados (Quadro 1) mostram grande variação na ocorrência de anticorpos anti-T. gondii (de 0% a 81,25%), semelhante ao obtido por Figliuolo et al (2004), com variação de positividade de 3,34% a 100%.…”

Esse agente tem como hospedeiros definitivos membros da família Felidae, entre os quais, gatos domésticos, que apresentam importante papel na epidemiologia da toxoplasmose, uma vez que contaminam águas e pastagens com oocistos eliminados nas fezes (Mainar et al 1996, Van Der Puije et al 2000, cuja ingestão é a principal via de transmissão para os herbívoros, como, por exemplo, os ovinos e os caprinos (Engeland et al 1996).…”

Objetivando avaliar a ocorrência de anticorpos anti-Toxoplasma gondii, em caprinos leiteiros do estado de São Paulo, e verificar possíveis associações com idade, sexo, presença de gatos, problemas reprodutivos e potenciais riscos à saúde pública, foram considerados soros de 923 caprinos, de ambos os sexos e idade acima de três meses, provenientes de 17 propriedades de diferentes municípios. Para o diagnóstico, utilizou-se a reação de imunofluorescência indireta (RIFIe"16) e, também, um inquérito sobre saúde, a fim de se coletarem informações epidemiológicas e de esfera reprodutiva de todos os capris. Os resultados foram discutidos no nível de 5% de significância. Do total das 17 propriedades, foram diagnosticados 15 focos de T. gondii, com positividade entre 2,70% e 81,25%. Não foram verificadas associações entre freqüência de soropositividade e sexo dos animais nem ocorrência de falhas reprodutivas, nos capris. Constatou-se influência positiva na taxa de anticorpos anti-T. gondii pelo aumento da idade dos caprinos e presença de gatos, nos capris. Além de a enfermidade encontrar-se amplamente difundida no estado de São Paulo, o risco eminente de transmissão de T. gondii à saúde pública também deve ser considerado, uma vez que se encontraram focos onde se comercializavam produtos "in natura", como leite e carne.

A Meta-Analysis of the Prevalence of Toxoplasmosis in Livestock and Poultry Worldwide

Toxoplasma gondii causes toxoplasmosis with a global prevalence in the world. A large proportion of human illness is most frequently associated with consuming raw and undercooked meat or other animal products containing infective parasitic stages of T. gondii . This systematic review and meta-analysis study evaluated the prevalence of toxoplasmosis in cattle, sheep, camels, goats, and poultry worldwide. The search was performed in databases including PubMed, WoS, Scopus, Science Direct, Google Scholar, and ISC from 2000 to 2019 in Persian and English. The main inclusion criteria were the prevalence of toxoplasmosis among livestock and poultry and the prevalence indices by sample size. During these 20 years, the overall prevalence of toxoplasmosis in livestock and poultry was 28.3% (95% confidence interval (CI) 25–31.9%) using the random-effects meta-analysis model. The highest prevalence of T. gondii in livestock and poultry animals was found in Asia in 2014 with 89.8% (95% CI 78.5–95.5%). The lowest prevalence was found in Asia in 2013 with 1.26% (95% CI 0.4–3.8%). A quarter of livestock and poultry were infected with T. gondii . Since livestock products are globally important sources of people's diet, our findings are useful for policymakers to control T. gondii infection in livestock.
