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 .

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.

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.

The aim of this study was to evaluate the prevalence of anti-Toxoplasma gondii antibodies and to identify risk factors associated to the infection in the three meso-regions of the State of Alagoas, Brazil. A total count of 23 towns and 27 meat sheep farms were visited where blood samples were collected in order to perform the indirect immunofluorescence test to evaluate the antibodies presence. Questionnaires exploring the production system and nutritional, sanitary, and reproduction handling were handed out. The prevalence rate was 32.9% and the number of foci was 100%. In the multivariate statistical analysis, there was a significant association for the following variables: age (OR = 4.01; C.I. 2.03-7.94), size of the property (or the farm; OR = 0.48; C.I. 0.26-0.90), semi-intensive rearing system (OR = 3.17; C.I. 1.24-8.13), running water source (OR = 3.13; C.I.-1.66-5.87), and presence of cats (OR = 1.72; C.I. 1.08-2.75). It is concluded that sheep of the three meso-regions of the State of Alagoas are exposed to the infection caused by T. gondii with high prevalence. Control and prophylactic measures must be adopted seeking the improvement of the rearing system and the implantation of health promoting programs in cooperation with sheep farmers in order to elucidate the transmission means of this disease.
