|The aim of this study was to determine and compare the seroprevalence of T. equi and B. caballi infection by cELISA and looking for the presence of ticks associated with the occurrence of the Equine Piroplasmosis (EP). Horses from two regions: tropical and subtropical of México were selected (Figure 1). One hundred horses from Torreón, Coahuila and seventy five horses from Villa Corzo, Chiapas with some clinical signs such as jaundice, lethargy, partial anorexia, weight loss and poor performance were selected for sampling. cELISA was used to detect antibodies of T. equi and B. caballi; and ticks were collected from fifty horse with for each region making a taxonomic study for each tick found as a competitive vector. Chi square test was applied to compare the rates of seroprevalence and were not statistical differences found. Sexes (P>0.05), According with the age, there were more seropositivity horses with less than five years that more than five years old (51% and 36%, respectively; P=0.06). We conclude that Torreón there was not EP infection but was very high prevalence at Villa Corzo, Chiapas and T. equi were the most prevalent hemoparasite. The distribution of seroprevalence is on Table 1. For the tick collection we found 32 tick species from 50 horses. Amblyoma cajennense 50% Amblyoma maculatum 31.25% Amblyoma imitator 18.75% for Villa Corzo and at Torreon we found 60 tick samples from 50 horses. Otobius megnini was 85%, Rhipicephalus sanguineus was 8.3% O. megnini + R. sanguineus was 5.0 and one larve not identificated 1.7%.|
