Diversity and Phylogeny of Cattle Ixodid Ticks and Associated Spotted Fever Group spp. in Tunisia.

Tick-borne rickettsioses are mainly caused by obligate intracellular bacteria belonging to the spotted fever group (SFG) of the genus. So far, the causative agents of SFG rickettsioses have not been detected in cattle ticks from Tunisia. Therefore, the aim of this study was to investigate the diversity and phylogeny of ticks associated with cattle from northern Tunisia and their associated species.

Screening and Analysis of Tunisian Isolates Reveal the Diversity of Phylogeographic Marker and the Conservation of OmpA Protein Vaccine Candidate.

Bovine anaplasmosis caused by is a disease responsible for serious animal health problems and great economic losses all over the world. Thereby, the identification of isolates from various bioclimatic areas in each country, the phylogeographic analysis of these isolates based on the most informative markers, and the evaluation of the most promising candidate antigens are crucial steps in developing effective vaccines against a wide range of strains. In order to contribute to this challenge, a total of 791 bovine samples from various bioclimatic areas of Tunisia were tested for the occurrence of DNA through gene fragment amplification.
