Abstract
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.
