[First serological study of the prevalence of Anaplasma phagocytophilum in dromedary (Camelus dromedarius) in Tunisia]. / Première étude sérologique de la prévalence d'Anaplasma phagocytophilum chez le dromadaire (Camelus dromedarius) en Tunisie.

The aim of the study was to evaluate the seroprevalence of Anaplasma phagocytophilum in dromedary (Camelus dromedarius). Sera of 226 healthy dromedaries from three regions of Tunisia (Sidi Bouzid, Bouficha and Douz) were tested by indirect immunofluorescence (IFA). The overall infection rate was estimated at 29.2%. The study of risk factors showed that region, age, gender, presence of ticks and types of breeding had no influence on the seroprevalence of A. phagocytophilum. This study indicates for the first time in Tunisia that dromedary may be involved in the natural cycle of A. phagocytophilum.
