Introduction: Infection of goats with caprine arthritis encephalitis virus (CAEV) has been detected in variable proportions in many countries all over the world. Here, we investigated the seroprevalence of CAEV in goats raised in Algeria. Material and Methods: A serological survey was performed on serum samples from 1,313 goats, including the local breeds (Arabia and Dwarf of Kabylia) and imported European breeds (Alpine and Saanen). Blood samples were taken from goats on 38 farms distributed across four different geographical regions of Algeria. Serum samples were tested for CAEV antibodies using a commercial ELISA. Results: A total of 390 serum samples were found to be positive for CAEV, giving an overall seropositivity rate of 29.7% in individual animals and 97.37% (37/38) at the goat farm level. Conclusion: These results provide the first large-scale serological evidence for the presence of CAEV infection in both the local and imported breeds of goats raised in Algeria, indicating that the virus infection is widespread.

The aim of this study was to investigate Q fever seroprevalence in sheep and goats in the Marmara region. Q fever is a zoonotic disease caused by Coxiella burnetii. In ruminants, the disease causes reproductive disorders, premature births and stillbirths. Blood samples of sheep and goats were collected from the Marmara region of Turkey and a commercial ELISA was used for detection of specific antibodies to C. burnetii. A total of 832 samples (627 from sheep and 205 from goats) obtained from 126 herds located in 110 villages in 63 municipalities across all 11 provinces were utilised. Total seroprevalence was found to be 13.22%, while the proportion of seropositive herds was determined to be over threefold higher at 42.85%. The seroprevalence for sheep was found to be 14.19%, and for goats 10.24%. The herd seropositivity rate for sheep of 46.31% and for goats of 32.25% were also over threefold higher than the species-level seroprevalences. The provincial seroprevalence varied between 1.38% and 21.79%. This study confirms the presence of C. burnetii in sheep and goat herds in the Marmara region and provides original seroprevalence data in hitherto uninvestigated provinces. The data gathered are beneficial for evaluation and elaboration of the seroprevalence of Q fever in sheep and goats in the Marmara region. Surveillance studies should be maintained, particularly in provinces with high seropositivity rates.
