Cystic echinococcosis (CE) is an important zoonotic infection caused by the larval stages of the genus Echinococcus. Turkey is a highly endemic region for CE and the disease is one of the major public health problems. The study was aimed to assess the situation of the CE in sheep in Turkey and also to provide data on circulating genotypes in the country. A total of 3319 sheep at slaughter were screened during the study. The prevalence of CE in the study area was 31.7% (1052/3319). The lungs were the most frequently CE infected organ (50%, 526/1052). Microscopic examination revealed that overall cyst fertility was 68.1%. Molecular analysis of partial fragments of 12S and COI gene regions were included for 351 selected cyst samples and all of them were identified as E. granulosus sensu stricto. Sequence analysis showed that the predominant genotype in the study areas was G1 (77.1%), and the rest were G3 (22.9%). The prevalence rate of CE in sheep in the study area is lower compared to previous years except for one province. Considering the high cyst fertility rate and the predominance of E. granulosus G1 which is particularly pathogenic to humans, calls for serious control measures like public awareness about the disease, sufficient dog deworming programs, continuity of monitoring the disease should be taken. |
