Anaplasmosis and ehrlichiosis are important tick-borne rickettsial diseases of medical and
veterinary importance that cause economic losses in livestock. In this study, the prevalence
of Anaplasma ovis, Ehrlichia canis and Ehrlichia chaffeensis was investigated in ticks collected
from sheep in various farms in Van province, which is located in the Eastern Anatolian Region
of Turkey. The ticks used in this study were collected by random sampling in 26 family farm
business in 13 districts of Van province. A total of 688 ticks were collected from 88 sheep and
88 tick pools were created. All ticks identified morphologically as Rhipicephalus bursa. Phylogenetic analysis of Chaperonin and 16S rRNA gene sequences confirmed A. ovis, E. canis and
E. chaffeensis in this study. Of the 88 tick pools tested, 28.41% (25/88) were positive for at least
one pathogen. Anaplasma DNA was detected in five of the 88 pools (5.68%), E. canis DNA
was detected in 19 of the 88 pools (21.59%), and E. chaffeensis DNA was detected in one
of the 88 pools (1.14%) of R. bursa ticks. To our knowledge, this is the first report describing
the presence of A. ovis, E. canis, and E. chaffeensis in R. bursa ticks collected from sheep
in Turkey. Further studies are needed to investigate other co-infections in sheep in Turkey.
