| sexual, seasonal and tissue variation in the encystment of cotylurus variegatus metacercariae in perch, perca fluviatilis. | all of the 267 perch sampled from lough neagh between 1981 and 1983 were infected with the metacercarial cysts of cotylurus variegatus. sites of infection were the swim-bladder, pericardium, septum transversum and, to a lesser extent, the visceral cavity. the swim-bladder, particularly the anterior portion, was the site of heaviest infection. visceral cysts were found chiefly in female fish and this may be related to reduced immunological defence and/or thinner body wall during the breeding seas ... | 1989 | 2759769 |
| [about the original materials of cotylurus platycephalus and cotylurus variegatus (creplin, 1952) (trematoda : strigeidae) (author's transl)]. | the examination of the original materials proves that cotylurus variegatus (creplin, 1825) is synonymous with c. platycephalus (creplin 1825), the better known of the two. their relative priority is determined by our action as first reviser (i.c.z.n., art. 24) cotylurus cumulitestis dubois, 1962 is considered to be a young adult of c. platycephalus. | 1978 | 677711 |
