Objective: To ascertain the prevalence of the Anaplasma/Ehrlichia infections in tick population\udwithin four provinces of Iran.\udMethods: A total of 384 tick specimens were collected from domestic animals inhabiting in\udfour provinces (East Azerbaijan, Gilan, South Khorasan and Yazd). Specimens were identified\udbased on morphological analysis. The detection of Anaplasma spp./Ehrlichia spp. within\udtick samples was carried out by nested PCR amplification of the 16S ribosomal RNA gene\udaccompanied by DNA sequencing and analysis for verification.\udResults: A total of 10 tick species were identified as follows: Ornithodoros lahorensis (O.\udlahorensis) (44.8%), Hyalomma dromedarii (15.6%), Dermacentor marginatus (13.5%),\udHyalomma anatolicum (11.2%), Hyalomma asiaticum (5.7%), Hyalomma marginatum (4.9%),\udRhipicephalus sanguineus (2.3%), Hyalomma detritum (1.0%), Dermacentor niveus (0.5%)\udand Argas persicus (0.3%). The percentage distribution of Anaplasma/Ehrlichia was 55.5%\ud(213) across 384 studied ticks.\udConclusions: To the best of our knowledge, this is the first report of Anaplasma ovis infection\udin O. lahorensis in Iran. We also conjecture the prevalence of Ehrlichia spp. in Yazd Province\udbased on sequencing results; also, it is suggested that O. lahorensis is a potential vector in the\udstudied area. This survey highlights the importance of Argasidae family to verify and correlate\udtheir threat in causing anaplasmosis and other diseases in animals
