[Analysis of tick-host parasitic specificity. Evaluation of the Madagascar situation and intense samplings]

Ticks are traditionally considered being host-specific parasites. The pattern of tick-host relationship was elucidated by exhaustive collection from a considerable number of potential hosts from numerous sites in the Malagasy mid-altitude forest. It can from the findings be concluded that the Malagasy ticks found on small mammals may be distinguished as either having a broad host-specificity or being highly host-specific. The results may provide important information in respect to phylogenetic studies with regards to the geological history of Madagascar and its endemic fauna.
