Abstract:
We studied the prevalence of rickettsialike organisms infection in different tick species (3154 adults) collected in several areas of the Ebro valley (Spain). The Gimenez stain showed a prevalence of rickettsia-like organisms in 38.6% of the studied ticks. Using the immunofluorescence assay, only two species, Rhipicephalus sanguineus (16.4%) and R. pusillus (19.9%) have shown organisms compatible with spotted fever group rickettsiae.
