Introduction: Although Cysticercus tenuicollis is one of the most economic and veterinary important parasite in Iraq, scanty molecular characterization exists for this helminth. This study aimed to determine the prevalence and molecular description of C. tenuicollis isolates from sheep in Kalar district of Iraq.
Methodology: A total of 2,906 slaughtered sheep were examined post-mortem. Up to 20 samples of C. tenuicollis was extracted and amplified using mitochondrial COX1 gene.
Results: The overall prevalence rate was 6.88%, and female sheep recorded higher rate of infection (24.35%) than male (6.16%) with significant difference (p<0.05). The molecular results showed 14 haplotypes for COX1 gene and the pairwise nucleotide variation among them was ranged from 0.2 to 2.6%. Twelve out of fourteen haplotypes of C. tenuicollis involving one to three base mutations were discovered in Kalar, Iraq for the first time and this could be a unique mutation internationally and did not registered previously. Eleven newly recorded haplotypes involved only one single mutation and the remaining one involved three mutations. Phylogenetic interpretation showed that Cysticercus tenuicollis-Kalar isolate were clustered in one clade, and closely related to isolates discovered in Nigeria, China, Turkey, Poland, and Iran.
Conclusions: This study provided a new record data on prevalence and discovered novel strains of C. tenuicollis in the study area for the first time named Cysticercus tenuicollis-Kalar isolate. Novel haplotypes might consider endemic genetic characterization of this metacestode. The present data may be useful to provide a good molecular background for future preventive and control programs.
