between Texas and Mexico. The tick Ixodes scapularis tends to be the main carrier for Borrelia bacteria‚ which causes borreliosis. Nonetheless‚ its absence in the area studied gave cue to the analysis of another tick‚ Amblyomma inornatum. It is important to characterize the disease potential of the latter tick in order to decrease the rate of population infected each year. In order to analyze the prevalence of the Borrelia‚ Rickettsia and Ehrlichia species (the causes of the diseases mentioned above) in
