“…Alternatively, Ogawa et al (2005), Vogel et al (2006), Corbellini et al (2006) and Oshiro et al (2007) reported lower seropositive values of 12%, 11.4%, 17.8% and 14.9%, respectively. In contrast, Boaventura et al (2006), Guimarães et al (2006), Locatelli-Dittrich et al (2008) and Benetti et al (2009), found 40.7%, 90%, 33% and 53.5% of positive animals had antibodies against N. caninum.…”

“…A prevalência encontrada neste estudo está abaixo das encontradas por Marana et al (1994) (GARRIDO et al, 1972;COSTA;COSTA, 1978;MARANA et al, 1994;OGAWA et al, 2005;ALBUQUERQUE et al, 2005), sendo que Garrido et al (1972) afirmaram que animais com títulos mais baixos possuem infecção latente e, com títulos mais elevados, possuem uma forma ativa da doença.…”

ResumoForam analisados 600 soros de bovinos abatidos nos matadouros sob Inspeção Municipal de Ilhéus e Itabuna, e no matadouro frigorífico sob Inspeção Federal em Jequié, BA, para anticorpos anti-Toxoplasma gondii por imunofluorescência indireta. A prevalência total foi de 11,83% (71), sendo os animais positivos 19,3% (37) no matadouro de Ilhéus, 9,8% em Itabuna (21) e 6,8% (13) em Jequié. Dos animais positivos, 65 (91,5%) tiveram título de 1:64, e 6 (8,5%) de 1:256. A maioria dos soros positivos para T. gondii foram oriundos de animais provenientes de granjas leiteiras e foram abatidos nos matadouros sob inspeção municipal em comparação com aqueles animais que procederam de fazendas com criação extensiva, e abatidos em matadouros sob inspeção federal.Palavras-chave: Toxoplasmose, prevalência, gado de abate. AbstractSerum samples of 600 slaughtered cattle from Ilhéus and Itabuna Municipal slaughterhouse and Jequié Federal slaughterhouse, all of them located in the State of Bahia were screened using an indirect immunofluorescent antibody test against Toxoplasma gondii. Prevalence was 11.83% (71), and positive samples were distributed as 19.3% (37) from Ilhéus, 9.8% (21) from Itabuna and 6.8% (13) from Jequié slaughterhouses respectively. From positive cattle, 91.5% (65) had titles 1:64, and 8.5% (6) had title 1:256. The majority of serum positive samples against T. gondii were related to animals from dairy farms which were slaughtered at municipality stockyards under municipal inspection in comparison with those slaughtered at Federal inspection which were related to beef cattle that were raised in farms extensively.

“…The seroprevalence of T. gondii infection in flocks of sheep in Brazil ranges from 7.0% to 54.6% (MOURA et al, 2007;OGAWA et al, 2003). The only study in Bahia state with sheep was carried out in the metropolitan region of Salvador and Recôncavo, with prevalence of 18.75% (GONDIM et al, 1999).…”

In this study, we aimed to determine the prevalence of Toxoplasma gondii antibodies and identify risk factors associated with this infection in sheep from the southern region of Bahia state. Between February and December 2010, 795 sheep from 31 farms located in nine municipalities were tested. We found seroprevalence of 30.2% (240/795), with titers of 64 (38.3%), 256 (34.2%), 1,024 (18.3%), and 4,096 (9.2%) by Indirect Fluorescent Antibody Test (IFAT). Seropositive sheep were detected in all farms sampled. Univariate statistical analysis detected association between T. gondii seropositivity and the variables age, use of fresh food mainly, water source, stocking rate, production system, presence and number of cats on the farm, and transit of cats (p < 0.05). In the logistic regression model, transit of cats (p = 0.001), production system (p = 0.007), and age (p = 0.027) were identified as risk factors associated with T. gondii infection.Keywords: Epidemiology, ovine, toxoplasmosis, zoonosis, risk factors. ResumoObjetivou-se com este estudo determinar a prevalência de anticorpos anti-Toxoplasma gondii e identificar os fatores de risco associados à infecção em ovinos no sudeste do Estado da Bahia. De fevereiro a dezembro de 2010, 795 ovinos de 31 propriedades localizadas em nove municípios foram analisados. A soroprevalência foi de 30,2% (240/795), com títulos de 64 (38,3%), 256 (34,2%), 1.024 (18,3%) e 4.096 (9,2%) pela Reação de Imunoflorescência Indireta (RIFI). Ovinos positivos foram detectados em todas as fazendas estudadas. Na análise estatística univariada detectou-se associação entre a soropositividade e idade, uso de alimentação fresca, fonte de água, sistema de produção, presença e número de gatos na fazenda e o transito de gatos (p < 0,05). No modelo de regressão logística, transito de gatos (p = 0,001), sistema de produção (p = 0,007) e idade (p = 0,027) foram identificados como fatores de risco associados à infecção por T. gondii.
