title: Abattoir prevalence, organ distribution, public health and economic importance of major metacestodes in sheep, goats and cattle in Fars, southern Iran.
abstract: Some of the metacestodes are not only zoonotic but are also responsible for severe   tissue damage, reduction in milk and meat production, and considerable economic loss due to   condemnation of the infected organs of the herbivorous animals. The aim of the present study   was to determine the prevalence of Cysticercus ovis, Cysticercus tenuicollis, hydatid cyst   and Coenurus gaigeri in sheep and goats and Cysticercus bovis, Cysticereus tenuicollis and   hydatid cyst in cattle. A total of 1050 sheep, 950 goats and 500 cattle slaughtered at Shiraz   Slaughterhouse were carefully examined for these metacestodes. Cysticercus tenuicollis   was found in 184 (17.52%) sheep and 523 (55.05%) goats. The prevalence of C. tenuicollis   was higher in males than females (P<0.01), and was higher in goats compared to sheep   (P<0.01). Hydatid cyst was found in 478 (45.52%) sheep and 95 (10.0%) goats and its prevalence   was higher in older animals compared to the younger ones. Coenurus gaigeri was found in 5   (0.48%) sheep and 17 (1.79%) goats and Cysticercus ovis was found in one male sheep only   (0.09%). Cysticercus bovis was found in 3 male cattle (0.6%) and hydatid cyst was found in 58   (11.6%) cattle. The prevalence of hydatid cyst was higher in older cattle compared to the   younger ones and higher in females than males. These results suggest that the high prevalence   of the metacestodes infestations in this area is a great concern for both medical and veterinary   authorities to design therapeutic and preventive programs to overcome this problem.
