Rango de distribución geográfica de garrapatas duras (Acari: Ixodidae) nativas que parasitan a los bovinos en áreas con ganadería extensiva de la provincia de Santa Fe, Argentina

Historical records of native hard tick species (Acari: Ixodidae) from Santa Fe Province, Argentina, were analyzed. From these records, areas of absence and occurrence were determined, and transects were drawn that were validated through new collections of ticks in the free-living (in vegetation) and parasitic (in cattle, humans and wild hosts) phases.Geographic distribution maps were developed for tick species of the genera Amblyomma, Haemaphysalis and Ixodes that have been reported parasitizing cattle and those that have not. As a result, eight species of ticks that have been previously recorded parasitizing cattle in the Neotropical region (A. aureolatum, A. dubitatum, A. parvum, A. sculptum, A. tigrinum, A. triste, H. juxtakochi and I. chacoensis) and six species of native ticks that do not parasitize cattle (A. argentinae, A. auricularium, A. calcaratum, A. ovale, H. leporispalustris and I. loricatus) were reported for Santa Fe Province. In addition, the parasite-host associations for each of them were described. Some of the recorded species are potential vectors of pathogenic microorganisms for humans. This information may be useful when outlining tick control strategies in cattle and for incorporating into epidemiological monitoring programs for zoonotic vector-borne diseases.
