Abstract :
Ticks are reservoir hosts of pathogenic Rickettsia in humans and domestic animals. Most pathogenic Rickettsia species belong to the spotted fever group (SFG). The present study aimed to determine the tick species infected with Rickettsia based on the genus-specific 23S ribosomal ribonucleic acid (rRNA), 16S rRNA, and citrate synthase (gltA) gene fragments. A total of 61 tick specimens were selected for molecular assay and 12 samples for sequencing. Phylogenetic analysis was conducted using neighbor-joining and Bayesian inference methods. Argas persicus, Haemaphysalis sulcata, Ha. inermis, and Hyalomma asiaticum were infected by spotted fever Rickettsia. The SFG is the main group of Rickettsia that can be detected in the three genera of ticks from Iran.
