title: Prevalence, predilection sites and pathological findings of Taenia multiceps coenuri in slaughtered goats from south-east Iran.
abstract: Coenurosis is a zoonotic disease in a variety of ruminants caused by the metacestode of Taenia  multiceps. The coenuri in the brain and spinal cord of sheep and goats have been identified as  Coenurus cerebralis whilst those reported in other tissues have been named Coenurus gaigeri.  This study was conducted during the spring and summer of 2011. Out of 25 739 goats inspected  in slaughterhouses, 23 carcasses (0.09%) revealed one or multiple visible swellings on the  different muscles and visceral organs. The coenuri, of variable sizes, were found mainly in the  muscles of the thigh, shoulder and neck, and were less common in the abdominal muscles and  subcutaneous tissues. Coenuri were also found in the diaphragm, tongue, intercostal muscles,  lung, parotid area and tunica adventitia of the aorta in a goat with severe infection. The brains  of slaughtered goats that had coenuri in their skeletal muscles were examined and coenuri were  found in two specimens (8.69%). The coenuri were located in the occipital lobe, the anterior  part of the right cerebrum and the parietal lobe of the left cerebrum. Histopathologically,  coenuri in the brain caused pressure atrophy and liquefactive necrosis in the surrounding  tissues, hyperaemia, perivascular cuffing, neuronal degeneration, neuronophagia, satellitosis,  diffuse microgliosis and astrocytosis. Coenuri in the skeletal muscles caused degenerative and  necrotic changes, hyalinisation and myositis. In the lung, tissues around the coenurus revealed  atelectasis and focal interstitial fibrosis. In the present study, concurrent occurrence of coenuri  in the central nervous system and skeletal muscles supports the hypothesis that C. cerebralis  and C. gaigeri are different names for the metacestodes of the same species of tapeworm.
