C. abortus infection is usually considered as the most important cause of caprine abortions (Chanton-Greutmann et al 2002, Czopowicz et al 2010 and it has been found to be the most common cause of abortions in goats in Hungary (Szeredi et al 2006) and in USA (Moeller 2001).…”

RESUMO.-[Soroprevalência e fatores de risco associados com a infecção porA cross-sectional study was carried out to determine the ϐlock--level prevalence of C. abortus infection in goats from the semiarid region of the Paraíba State, Northeast region of Brazil, as well as to identify risk factors associated with the infection. Flocks were randomly selected and a pre-established number of female goats ≥ 12 mo old were sampled in each of these ϐlocks. A total of 975 serum samples from 110 ϐlocks were collected, and structured questionnaire focusing on risk factors for C. abortus infection was given to each farmer at the time of blood collection. For the serological diagnosis the complement ϐixation test (CFT) using C. abortus S26/3 strain as antigen was performed. The ϐlock-level factors for C. abortus prevalence were tested using multivariate logistic regression model. Fifty-ϐive ϐlocks out of 110 presented at least one seropositive animal with an overall prevalence of 50.0% (95%; CI: 40.3%, 59.7%). Ninety-one out of 975 dairy goats examined were seropositive with titers ≥32, resulting in a frequency of 9.3%. Lend buck for breeding (odds ratio = 2.35; 95% CI: 1.04-5.33) and history of abortions (odds ratio = 3.06; 95% CI: 1.37-6.80) were associated with increased ϐlock prevalence. para determinar a prevalência de rebanhos positivos para a infecção por C. abortus em caprinos do semiárido do Estado da Paraíba, Nordeste do Brasil, bem como identiϐicar os fatores de risco associados com a infecção. Os rebanhos foram selecionados aleatoriamente e um número pré-estabelecido de cabras com idade ≥12 meses foi amostrado por rebanho. No total, foi colhido sangue de 975 animais procedentes de 110 rebanhos, e no momento da colheita foi aplicado um questionário epidemiológico a cada proprietário. Para o diagnóstico sorológico foi utilizado o teste de ϐixação de complemento (FC) usando a estirpe de C. abortus S26/3 como antígeno. Os fatores de risco para a prevalência de C. abortus em nível de rebanho foram testados com o uso de modelo de regressão logística multivariada. Cinquenta e cinco rebanhos dos 110 analisados apresentaram pelo menos um animal soropositivo, com uma prevalência de 50,0% (IC 95%: 40,7%).

“…A limited number of studies have been performed examining the presence of C. burnetii in bovine, ovine, and caprine aborts in different countries (Sanchez et al 2006;Szeredi et al 2006;Jensen et al 2007;Hazlett et al 2013). Sheep aborts were positive for the presence of C. burnetii in 3.7% of cases in Germany (Plagemann 1989), 1% in Switzerland (Chanton-Greutmann et al 2002), and 2% in Hungary (Szeredi et al 2006).…”

Positivity for the agent was also found in 17.2% of bovine aborts in Portugal (Clemente et al 2009) and 11.6% in Italy (Parisi et al 2006).…”

This study was aimed at detection of Coxiella burnetii in bovine foetuses using polymerase chain reaction (PCR) and immunohistochemistry (IHC) and at an estimation of its frequency in Eastern Turkey. Stamp, Giemsa, and Gimenez stains were used in addition to PCR and IHC to determine the presence of C. burnetii in samples from 70 bovine foetuses. While the staining methods did not detect the agent by direct visualisation of C. burnetii on smears, PCR and IHC identified its presence in two of the foetuses. The distribution of antigens in these two foetuses was, in decreasing order of concentration, in the spleen, the thymus, the lungs, the liver, and the kidneys. We conclude that C. burnetii diagnosis in bovine foetuses can be reliably performed using PCR and IHC. In addition, the frequency of 1.42% of C. burnetii positivity in bovine foetuses reported here was the first time that the presence of this agent was determined in Eastern Turkey.

“…The pathogen is experimentally proven to cause abortions (Rodolakis et al 1984) and has been frequently isolated from clinical cases of abortions in goats (Moeller 2001, Szeredi et al 2006, Navarro et al 2009). Epidemiological confirmation of its role in fetal loss, given that apparent herd-level prevalence was very small, seems to be very important information and raises concerns as to the situation in forthcoming years.…”

The observational study was carried out in a population of Polish breeding goats in 2007 to determine the prevalence of fetal loss and identify risk factors contributing to its occurrence. The multivariate model allowing to predict the risk of the occurrence of fetal loss in a herd in a study population was developed. Data on the occurrence of fetal loss, as well as of 28 hypothesized risk factors were collected from goat owners using standardized questionnaire during face-to-face reviews on farms. Moreover, data on the herd-level seroprevalence of four abortifacient infections -Chlamydophila abortus, Leptospira spp., BVDV-1 and Neospora caninum -were included in the final analysis. Fetal loss was reported as occurring often in 12 of 49 goat herds (24.5%). The relationship between the hypothesized risk factors and the occurrence of fetal loss was verified in the multivariate logistic regression (α=0.05). Final analysis yielded four risk factors: regular veterinary supervision at least twice a year (OR 0.188; CI 95% 0.054 -0.656), frequent occurrence of injuries and fractures (OR 3.172; CI 95% 1.081 -9.310), frequent occurrence of respiratory signs in adult goats (OR 4.848; CI 95% 1.353 -17.377) and presence of antibodies to C. abortus in a herd (OR 58.116; CI 95% 1.369 -2466.438). The accuracy of the multivariate model was analyzed using receiver operating characteristic (ROC) curve technique. Area under the curve was 0.895 (CI 95% 0.801-0.981). For optimal cut-off value of 0.20-0.35 the multivariate model had sensitivity of 75.00% and specificity of 89.19% in predicting fetal loss in a herd.
