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.
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.
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.
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.
本研究首次采用分子技术在锡瓦斯省调查绵羊和山羊中的 和相关株(-样 1 和样 2)。
研究材料由锡瓦斯省四个地区(锡瓦斯市中心、坎加尔、科伊利希萨尔和耶尔德勒姆)的 247 只动物(159 只绵羊和 88 只山羊)血液样本组成。采用聚合酶链反应(PCR)、PCR-RFLP 和 DNA 序列分析筛查 和相关株。
使用 PCR 在 44.93%(111/247)的小反刍动物中发现了相关株。绵羊的感染率为 45.91%(73/159),山羊的感染率为 43.18%(38/88)。在这项研究中,110 个样本仅对 -样 1 呈阳性,而在一个样本中 -样 1 和样 2 呈混合感染。在绵羊或山羊中未检测到 。随机选择两个 PCR 产物进行双向测序,并将共识序列在 GenBank 中注册,登录号为:ON598644 和 ON598645。本研究中获得的 -样 1 分离株与 GenBank 数据库中存在的 -样 1 分离株之间的核苷酸相似性为 99.34-100%。
本研究提供了锡瓦斯省 -样 1 和样 2 的首次分子数据。考虑到绵羊和山羊中 -样 1 的高阳性率,有关病原体的临床症状和载体物种的数据很少。因此,需要进一步研究来调查宿主中病原体的媒介蜱种和临床症状。
