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.

Taenia multiceps is a taeniid cestode that inhabits the small intestines of both wild and domestic carnivores. The larval stage, Coenurus cerebralis, is typically found in the central nervous system (CNS) of a wide range of livestock and, to a lesser extent, in the extra-cerebral tissues of sheep and goats. This review covers all aspects of the life cycle of T.

During the routine postmortem inspection from carcasses and offal of slaughtered ewes in an abattoir in Isfahan (Iran), an ovine heart was discovered with a firm nodule in the myocard on palpation. In closer examination, a liquid containing cyst (1x1 cm) was recognized on left part of the heart. The cyst had thick fibrotic capsule in outer surface and a thin inner layer containing few white clusters of scolices.

Background: Introduction of and as two separate species have been recognized mainly on morphological grounds. This experimental study was conducted to test whether cerebral and non-cerebral forms of belong to one origin or they are originated from two different tape worms.
Methods: Two groups of dogs were infected with the cerebral and muscular sources of the coenuri cysts.

Coenurus cerebralis is the larval stage of Taenia multiceps, which infects the muscles and brain of goats and, to a lesser extent, sheep. The resulting cerebral and non-cerebral infections caused by the larval form (metacestode) of this cestode are commonly known as coenurosis. A weak emaciated carcass of five months old female goat, on necropsy, revealed numerous parasitic cysts (n = 56, grossly visible) in the visceral cavity including heart, diaphragm, thoracic cavity, abdominal cavity and pelvic inlet.
