Abstract :

Background and Aim: Coenurus cerebralis is the intermediate stage of the canine cestode, which infect sheep and goats, resulting mainly in neurological signs and causing direct and indirect economic losses. This study aimed to demonstrate the existence of C. cerebralis and to elucidate the role of this parasite in inducing neurological behaviors in sheep and goats. Materials and Methods: On the basis of historical data on neurological signs, we subjected 76 animals (49 sheep and 27 goats) of different ages, sexes, and geographical areas for molecular examination of their blood samples using the polymerase chain reaction assay. Results: Of the 76 animals, 23.68% tested positive for C. cerebralis infection. We found significant increases in infection (p 0.05) variation between sheep ages [greater than or equal to] 1-3 years and [greater than or equal to] 3 years; however, both groups had a significantly (p [less than or equal to] 0.043) higher positivity rate than did sheep ages Conclusion: To the best of our knowledge, this study is the first report in Iraq targeting detection of C. cerebralis in sheep and goats with neurological behaviors; therefore, additional studies involving different animals in other regions using molecular techniques are needed. Keywords: definitive, intermediate host, Iraq, polymerase chain reaction, Taenia multiceps.
