coe·nu·rus C0455200 (sĭ-no͝or′əs, -nyo͝or′-)n. pl. coe·nu·ri (-no͝or′ī′, -nyo͝or′ī′) The parasitic larval stage of the tapeworm Taenia multiceps that consists of a cyst in which the scolex develops and that infects the central nervous system of vertebrates, including ruminants and canids. [New Latin coenūrus, having a common tail (from the fact that the larva has many heads) : coen(o)- + Greek ourā, tail; see ors- in Indo-European roots.]coenurus (siːˈnjʊərəs) n, pl -ri (-raɪ) (Animals) an encysted larval form of the tapeworm Multiceps, containing many encapsulated heads. In sheep it can cause the gid, and when eaten by dogs it develops into several adult forms[C19: from New Latin, from coeno- + Greek oura tail, literally: common tail, referring to the single body with its many heads]CoenurusenUK
Coenurus a variant of the cyst stage in the development of tapeworms. The coenurus has numerous heads, which are twisted into the cavity of the cyst. The coenuri of 31 species of the genus Multiceps have been described. That of Multiceps skrjabini may reach 35 cm in diameter. The cysticercus of this type, with a diameter up to 10 cm, is characteristic of Multiceps multiceps, which in its adult state parasitizes the intestinal tract of dogs and other canines and in the coenurus stage parasitizes the brains of sheep and occasionally of cattle, horses, and humans. Coenuri cause diseases known as coenuroses. coenurusenUK
Coenurus (sē-nū'rŭs), Former generic name, now used to designate larval forms of taenioid cestodes in which a bladder is formed with a number of invaginated scoleces developing within; distinguished from a hydatid cyst by the absence of free-floating daughter cyst colonies budded off within the bladder; C. larvae are found in members of the genus Multiceps. [G. koinos, common, + oura, tail] coenurus (sĭ-no͝or′əs, -nyo͝or′-)n. pl. coe·nuri (-no͝or′ī′, -nyo͝or′ī′) The parasitic larval stage of the tapeworm Taenia multiceps that consists of a cyst in which the scolex develops and that infects the central nervous system of vertebrates, including ruminants and canids. |
