چکیده

OBJECTIVE Bovine cysticercosis is a cattle infection caused by a tapeworm, Taenia saginata. While the condition is relatively innocuous, the parasite infects the small intestine of humans in its mature stage and causes a few specific symptoms such as abdominal pain and nausea. METHODS Between February 2013 and February 2014, a total of 640 cattle were randomly selected from all the cattle sent to the abattoir, and some internal organs and skeletal muscles of these cattle were inspected. RESULTS Overall, 11 (1.71%) cattle were infected with the larval form of the cestode parasite T. saginata. In addition, the infection was more prevalent in cattle aged above 12 months than in those aged below 12 months [10 (2.06%) vs. 1 (0.64%)]. The prevalence of infection was significantly higher in female animals [8 (3.72%)] than in male animals [3 (0.70%)] (p<0.05). However, no significant difference was found between the rates in the 2 age groups or in different seasons. While the infections were detected in several visceral organs, no significant difference was found between their infection rates. CONCLUSION The comparatively high prevalence of Cysticercus bovis infection in the cattle in Tabriz, Iran, may contribute to economic and health problems in the country's meat industry. On the other hand, the role of public health education in C. bovis infection control cannot be neglected.
