Abstract:
Bred mixed animals (Ndama x Abondance (Ndamance), Ndamance x Montbeliard, Ndamance x
Holstein) following in traditional and modern herds, allowed us to know the ticks genus and species and
their seasonal variation in savannah region of North Cote d’Ivoire.
Amblyomma variegatum level of infestation was higher in such breed than local one (up to 1200
adults ticks per animal) and Dermatophilosis impact was important (up to 90% for untreated animals) with
lesions, sometimes, extended to all the body. Slight wound was seen in predilections areas of Amblyomma
adults localized in udder or scrotum regions. Others adverse effects were observed as anemia and weight
loss. The PVC value was frequently observed before animal’s death. At clinical level, Heartwater was
identified only once. The prevalence of Theileria sp, Babesia bovis and B. bigemina was observed from blood
smears were 5%, 0.1% and 0.05% respectively. The rate of follow up treatment rate was not adapted to
seasonal variation of ticks, including Amblyomma variegatum.
