A survey of Taenia multiceps coenurosis in Sardinian sheep.
A survey was carried out to assess the occurrence of Coenurus cerebralis infection in Sardinian sheep. A prevalence of 0.35% was observed when 566 regularly slaughtered sheep were examined. However, in 120 sheep with suspected symptoms of coenurosis examined from November 2001 to October 2002, a total of 299 cerebral coenurosis lesions were observed with an incidence of 1% per year. Lesions were classified as migratory, cystic and secondary. Most migratory lesions were found in sheep aged 3-6 months. Cavitary lesions containing cysts in different developing stages were found with high incidence per year in sheep aged 7-12 months. Secondary lesions due to the development of Coenurus were most frequent in sheep aged 19-36 months. Most sheep were found infected in spring and in early summer, between March and June. Most lesions were located in the cortex. The mean number of protoscolices per cyst was 149 (range 10-370).
