Genetic analysis of Rhipicephalus sanguineus sensu lato ticks parasites of dogs in Africa north of the Sahara based on mitochondrial DNA sequences.

The aim of this work was to determine the evolutionary relationship among tick populations of Rhipicephalus sanguineus sensu lato distributed in Africa north of the Sahara and different lineages of R. sanguineus s.l.

The presence of Rhipicephalus muhsamae north of the Sahara.

The occurrence of male and female Rhipicephalus muhsamae feeding on dogs and a horse in Upper Egypt is described. The morphological identification was verified using partial 16S rRNA gene sequences. By applying respective real-time PCRs, no evidence neither for Coxiella burnetii nor for spotted-fever rickettsia infections were found in the ticks.
