Molecular Survey of and Related Strains in Sheep and Goats from Sivas; with a High Prevalence of -like 1.

Objective: This study aimed to investigate and related strains (-like 1 and like 2) in sheep and goats for the first time in Sivas province with molecular techniques.

Methods: The study material was composed of 247 animal (159 sheep and 88 goats) blood samples from four districts of Sivas province (Sivas City Center, Kangal, Koyulhisar, and Yıldızeli). and related strains were screened with polymerase chain reaction (PCR), PCR-RFLP, and DNA sequence analysis.

Results: related strains were found in 44.93% (111/247) of the small ruminants using PCR. The infection rate was 45.91% (73/159) in sheep and 43.18% (38/88) in goats. In this study, 110 samples were positive for only -like 1, while -like 1 and like 2 were mix-infection in one sample. was not detected in sheep or goats. Two randomly selected PCR products were sequenced in both directions, and the consensus sequences were deposited on the GenBank under accession numbers: ON598644 and ON598645. Nucleotide similarity of 99.34-100% was determined between -like 1 isolates obtained in this study and those of -like 1 isolates present in the GenBank database.

Conclusion: This study provides the first molecular data on -like 1 and like 2 in Sivas province. Considering the high positive rate of the -like 1 in sheep and goats, there is a paucity of data on clinical symptoms and vector species of the pathogen. Therefore, further studies are needed to investigate the vector tick species and clinical symptoms of the pathogen in the host.
