To determine the tick species parasitizing domestic ruminants in Zabol, Zahak and Qaen Counties which are located in east of Iran and are bordered with Afghanistan country, about 73 sheep, 44 goats and 27 cattle of 12 herds in several villages in Zabol, Zahak and Qaen Counties were inspected for tick infestation. Separated ticks were preserved in 70% alcohol and identified. About 464 ticks (252 male;194 female) were collected;the occurrences of ticks on goats, cattle and sheep were about 17%, 15% and 26% respectively in all three Counties. The mean number of ticks on each animal was about 2 - 7 ticks per animal. Totally we found 3 genera hard ticks including Hyalomma, Rhipicephalus and Dermacentor in these regions. Hyalomma anatolicum, Hy. marginatum, Hy. asiaticum, Hy. detrinium, Rhipicephalus bursa, R. sanguineus, Dermacentorniveus, and D. marginatus, were the tick species we found. Hyalomma anatolicum and Hy. asiaticum were the most abundant species in the study area. The result of this study is a survey of tick species from domestic animals in east part of Iran and implication of possible prevention measures for diseases transmitted by ticks.

Anaplasmosis, a disease caused by various species of Anaplasma, poses important economic constraints to animal breeders. Ehrlichiosis is a worldwide zoonosis illness and mostly occurs in tropical and subtropical regions that are close to the vector’s distribution. Tick-borne pathogens lead to over 100,000 cases of illness in the world each year. Besides the costs of the additional veterinary care, anaplasmosis causes abortion in animals, reduction of milk production, body weight, and frequently leads to death. In this study, we investigated on infection of ticks to Anaplasma and Ehrlichia pathogens in Zabol and Zahak County in Sistan and Baluchestan Province where is bordered with Afghanistan. Totally from June 2013 to May 2014, 369 ticks were caught from goats, cows and sheep. Molecular studies on 53 of these samples which represented all specimens, showed that Ehrlichia’s DNA and Anaplasma’s DNA was found in 14 (26.4%) out of the 53 selected specimens. The results showed the infection of Rhipicephalus sanguineus and Hyalomma anatolicum with Anaplasma ovis. Also we saw infection of H. anatolicum and H. asiaticum ticks to Ehrlichia spp. This study has been intended to do a comprehensive survey of Ehrlichia and Anaplasma distribution in ticks caught from east of Iran;it was designed to investigate the presence of Anaplasma spp. and Ehrlichia spp. in Zabol and Zahak Counties, Iran. These results show that these pathogens should be controlled in such regions.
