gastrointestinal helminths of cuvier's beaked whales, ziphius cavirostris, from the western mediterranean.we examined the gastrointestinal helminth fauna of 2 cuvier's beaked whales, ziphius cavirostris, stranded on the spanish mediterranean coast. information regarding intestinal parasites of this species is provided for the first time. six helminth taxa were identified. thirty type ii larvae of the nematode anisakis sp. were found in the stomach and the intestine of both hosts; 2 type i larvae of anisakis sp. were found in the intestine of 1 host. one juvenile of the acanthocephalan bolbosoma vasc ...200415165073
[the parasite fauna of the chub mackerel (scombridae: scomber japonicus houttuyn, 1782) in the central-eastern atlantic (atlantic coast of the northern africa and the azores archipelago banks)].the parasite fauna of the chub mackerel scomber japonicus houtuym, 1782 was studied from the neritic areas of morocco, western sahara, mauritania and from the banks of the azores archipelago (the great meteor bank, the hyeres bank and the irving bank) in 1994-2001. twenty eight species of parasites of following group have been were found: coccidia (1 species), microsporidia (1), myxosporea (4), monogenea (4), cestoda (5), trematoda (5), acanthocephala (1) and nematoda (6). the differences betwee ...200415174392
infection status with helminthes in feral cats purchased from a market in busan, republic of korea.the present study was performed to investigate the infection status with helminth in a group of feral cats in korea. more than 29 helminth species including adults or eggs were detected in visceral and fecal samples of the examined cats. among these were a host of nematodes, including toxocarids, ancylostoma sp. and the larva of anisakis simplex; trematodes, including clonorchis sinensis, paragonimus westermani, eurytrema pancreaticum, pharyngostomum cordatum, metagonimus spp., heterophyes nocen ...200516192750
