Geographical distribution and phylogenetic analysis of Rhipicephalus sanguineus sensu lato in northern and central Chile
MetadataShow full item record
The presented study analyzed the presence and geographical distribution of the tropical and temperate lineages of Rhipicephalus sanguineus sensu lato in Chile. R. sanguineus s.l. ticks were collected from dogs at 14 sites in northern and central Chile for morphological and genetic analysis based on the 16S rDNA gene. Phylogenetic studies proved the existence of both, the tropical and the temperate lineages. The former was represented by a single haplotype and occurred in the far north; the latter included four haplotypes and was observed from the Tarapaca Region southwards. In four sites at latitudes from 20 degrees S to 22 degrees S, both lineages were found to coexist. Our study discovered for the first time the existence of the tropical lineage in Chile and demonstrated that distributions of the tropical and temperate lineages overlap, forming a transitional zone of approximately 200 km in northern coastal Chile.
