Abstract

Bovine genital campylobacteriosis is one of the most economically important diseases of dairy cattle
resulting in lowered fertility, embryo mortality and abortion, repeated returns to service, reduced pregnancy
rates and extended calving intervals. While the occurrence of repeat breeding syndrome and abortions are
reported from many Iranian dairy cattle farms, little information is available regarding the presence of bovine
genital campylobacteriosis in Iran. The present report describes detection of Campylobacter fetus subsp.
venerealis infection in two out of eight repeat breeder Holstein Friesian cows (Bos Taurus) using a PCR
method in a herd with a history of subfertility in Mashhad, in the northeast of Iran.
