Abstract

Introduction: Taenia multiceps is the main cause of CNS coenurosis of ruminants and rarely in humans. This disease causes clinical signs and economic losses in livestock farms.
Objectives: The aim of this study was to determine the frequency of infection with metacestode Coenurus cerebralis in ruminants in ShahinDezh county and suburban villages.
Methods: Sampling was randomly conducted from butcheries (9 cattle, 30 sheep and 2 goats), Kallehpazi shop (5 cattle, 11 sheep and 1 goats), and slaughterred ruminants (29 sheep and 5 goats) in ShahinDej County. A total number of 92 ruminants (14 cattle, 70 sheep and 8 goats) was also examined in seven suburban villages. The skull of examined ruminants was separated and opened to examine the brain and cerebellum for the presence of the metacestode.
Results: Frequency of infection to C. cerebralis in butcheries was 26.26% in sheep and 50% in goats, and in Kallehpazi shop was 54.54% in sheep. The frequency of infection t in sheep in Kallehpazi shop was significantly higher than butcheries. The frequency of infection in suburban villages was 10% in sheep and 12.5% in goats. There was no significant difference between frequency of infection and age in the region. All cysts of C. cerebralis were found in cerebral hemispheres.
Conclusion: The results indicated the metacestode infection exist in sheep and goats in the region. With regards to this, it is recommended to implement control measures, ruminants’ owners training, and dog population control in the region.
