N. caninum could cause abortion in small ruminants. The aim of the study was to detect N. caninum infection in ovine aborted foetuses in the Mashhad area by PCR examination. During the period 2009 to 2013, 71 ovine aborted foetuses were collected and their brain samples examined by PCR. Of the 71 brains of the aborted foetuses, N. caninum DNA was detected in seven (9.8%) samples. In conclusion, it seems that N. caninum may act as a causative agent of abortion in sheep in the Mashhad area.
