“…To date, only two small ruminant seroprevalence studies have been performed in Algeria, collecting sera from sheep and goats [ 24 , 31 ]. Interestingly, one study from the North Central Region of Algeria [ 31 ] showed a global individual seroprevalence of 24.9%, which is higher than the seroprevalence detected in our study. This discrepancy may indicate the spread of C. burnetii , especially since both studies used the same enzyme immunoassays.…”

Q fever is a zoonotic disease caused by Coxiella burnetii (C. burnetii), a pathogen with a high capability for infection. The disease primarily affects ruminants, leading to reproductive disorders, but can also be transmitted to humans through contact with infected animals or their products. In Algeria, Q fever is endemic, but little is known about the presence and circulation of C. burnetii in domestic goats. This study aimed to perform a multicentric serological analysis of C. burnetii antibodies in domestic goats from four provinces in the North East Region of Algeria. A total of 504 goat serum samples were collected from 77 herds, and serological analysis was performed using an indirect ELISA. The overall seroprevalence at the herd level was 35.06%, and 8.73% at the individual level. Herds with a history of abortions showed a high seropositivity rate of 88.9%. This research indicates the wide distribution of C. burnetii in goats in this region, suggesting the potential for zoonotic transmission to humans. Further studies and monitoring programs are essential to gain a comprehensive understanding of C. burnetii epidemiology in Algeria and to prevent or mitigate potential outbreaks. Awareness among practitioners and farmers is crucial to address this public health concern effectively.
