RESUMEN
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.

The seroprevalence of ehrlichiosis was investigated in 1,216 dogs from eight administrative areas in five regions with different climates. In and around Tunis, where the animals receive satisfactory care, the average prevalence is 49%, but it ranges from 75 to 85% in the other regions of the interior. The authors underline the importance of this disease and describe the conditions which favour its transmission. They also note that the high percentage of asymptomatic carriers provides further proof that Ehrlichia canis is an opportunist pathogen in endemic areas.
