| Popis: | The A. cajennense tick complex has been thought to be the main vector of Rickettsia rickettsii in Central and South America. Studies in Colombia have determined the presence of species A. patinoi and A. mixtum of the A. cajennense complex, but it is unknown which species of this complex exist in northwestern Colombia. Our aim was to identify the species of the A. cajennense complex that are present in northwestern Colombia. We sampled ticks of A. cajennense sensu lato infesting equids. Females identified according to the morphology of their genital pore were selected for genetic confirmation. Specimens from each locality were selected to perform molecular and genetic analysis. Specimens were analyzed from five departments (Antioquia, Bolivar, Cordoba, Magdalena, and Sucre). Morphologically 65 specimens were identified as A. patinoi and 5 as A. mixtum. Molecular analysis allowed to confirm the morphological identification of 27 specimens. In this study A. patinoi was widely distributed in the departments of Antioquia, Bolivar, and Cordoba with allopatric and sympatric distribution in some places. These two species in the region could have unexpected effects on the epidemiology of rickettsiosis. |
