Abortion in small ruminants is one of the most prominent problems of livestock in many countries including Jordan. Our previous results regarding abortion revealed several undiagnosed cases with pathological lesions in placenta. This paper aims to expand our study to investigate the pathological lesions of Campylobacter as an abortive agent. Seventy-six aborted fetuses (17 goats and 59 sheep) and placenta of 53 fetuses were collected from farms in northern Jordan (2018 – 2019). The 76 available fetal liver and 53 placenta tissue were fixed with 10% NBF for histopathological and molecular investigations. Histopathological examination revealed that 17.11% cases had compatible histopathological lesions of Campylobacter. The 10.53% had multifocal hepatic necrosis with mild to moderate inflammatory reaction, 3 of which were positive using Campylobacter qPCR. On the other hand, qPCR detected 5 more positive cases but with no notable hepatic necrosis. All the placentas of the 8 qPCR positive cases had necrosuppurative placentitis. The age of 6 fetuses was estimated to be aborted at the third trimester and 2 at the second trimester based on the crown-rump length. This is the first pathological and molecular study to confirm the role of Campylobacter as abortive agent in small ruminants in Jordan.
