Non-cerebral coenurosis in goats

Three hundred carcasses of young goats aged between 3 and 6 months were found to be infested with cysts at routine meat inspection at an abattoir in Dubai in 2008. Two types of cestode larvae were situated in the liver, abdominal cavities, under the skin and between the fasciae of the skeletal muscles. Sixty-two typical coenuri loaded with multiple scolices (between 46 and 474) and situated in clusters (between 6 and 17) at the inner membrane of the bladder were recorded in numbers between one and 12 in 30 animals. The volume of coenuri cysts varied between one and 40 ml. The rostellum of 300-400 microm in diameter carried 26 to 32 hooks arranged in two circles. The average length of larger and smaller hooks was 160 and 114 microm, respectively. All other metacestodes were determined as Cysticercus tenuicollis. Although the structure of coenuri and the measurements of scolices were identical with Coenurus cerebralis, the location of these metacestodes outside the central nervous system, suggests that these larvae might belong to a different strain of Multiceps multiceps or even to a closely related species.
