Survey of seroprevalence of Q fever in dogs in the southeast of France, French Guyana, Martinique, Senegal and the Ivory Coast

A serological survey was carried out on 429 dogs belonging to the French mi litary in France, French Guyana, Martinique, Senegal and the Ivory Coast. S erology against phase I and II antigens of Coxiella burnetii, the intracell ular zoonotic bacterium was performed using indirect immunofluorescence tec hniques. Specific antibodies were found in dogs from France (9.8%), Senegal (11.6%), Ivory Coast (8.3%), French Guyana (5.2%) but not in those from Ma rtinique. The seroprevalence among 77 dogs who had contact with sheep compa red with 352 dogs who had had no contact, demonstrated a significantly high er seroprevalence in the former. Our results indicate that dogs, living clo se to sheep, may be infected by Coxiella burnetii and should be considered as possible sources of infection for humans. (C) 1998 Elsevier Science B.V.
