| a description of lecithocladium angustiovum (digenea: hemiuridae) in short mackerel, rastrelliger brachysoma (scombridae), of indonesia. | lecithocladium angustiovum is identified from the stomach (87.33%) and the intestine (12.67%) of indonesian short mackerel (rastrelliger brachysoma). the description includes an elongated body; a mean total length of 1018.84 µm; and an ecsoma of 47.52% of the total length. the oral and ventral sucker ratio is 1:0.63, and the pharynx length is 97.42 µm. the sequence results were obtained by 18s rdna gene sequencing of the 354 basepair (bp) dna segment, and the mean base composition (%) was 17.7 a ... | 2015 | 26868591 |
| Parasite communities and feeding ecology of the European sprat (Sprattus sprattus L.) over its range of distribution. | The metazoan parasite fauna and feeding ecology of 165 Sprattus sprattus (L., 1758) was studied from different geographic regions (Baltic Sea, North Sea, English Channel, Bay of Biscay, Mediterranean Sea). A total of 13 metazoan parasite species were identified including six Digenea, one Monogenea, two Cestoda, two Nematoda and two Crustacea. Didymozoidae indet., Lecithocladium excisum and Bomolochidae indet. represent new host records. The parasite species richness differed according to regions ... | 2011 | 21850453 |
| gastrointestinal helminth communities of the blackspot seabream pagellus bogaraveo (teleostei: sparidae) from portuguese north-east atlantic waters. | a study was carried out on the gastrointestinal helminth communities of blackspot seabream, pagellus bogaraveo, from the portuguese mainland and island waters. fifteen helminth parasite species were detected, including the following new records in this host: the digeneans accacladocoelium petasiporum, brachyenteron helicoleni, glomericirrus macrouri, lecithocladium excisum, lepocreadium album and pachycreadium carnosum; the nematode camallanus sp. and the acanthocephalan rhadinorhynchus pristis. ... | 2014 | 23182041 |
| ultrastructure of the spermatozoon of the digenean lecithocladium excisum (rudolphi, 1819) (hemiuroidea: hemiuridae), a parasite of marine teleosts in senegal. | the present study describes the ultrastructure of the mature spermatozoon of lecithocladium excisum (rudolphi, 1819) (digenea: hemiuroidea: hemiuridae) from the stomach of the marine teleost scomber japonicus houttuyn (scombridae) captured in the atlantic ocean, off dakar (senegal). the ultrastructural organization of the spermatozoon of l. excisum follows the general model described in most digeneans. it presents two axonemes of the 9+'1' pattern of the trepaxonemata, nucleus, mitochondrion and ... | 2012 | 23136797 |
| aspects of the morphology and life cycle of lecithocladium excisum (digenea, hemiuridae), a parasite of scomber spp. | previously undescribed motile cystophorous cercariae which develop in sporocyst-like germinal sacs in the bullomorph opisthobranch philine aperta are experimentally shown to develop into lecithocladium excisum (digenea, hemiuridae), a common stomach parasite of mackerel scomber scombrus in the north-east atlantic and adjacent seas. between 3 and 8% of p. aperta from the northern oresund, denmark, were infected with cercariae of l. excisum. ninety per cent were infected with rhopalura sp. (orthon ... | 1991 | 1743856 |
| life cycle and structure of the fish digenean brachyphallus crenatus (hemiuridae). | cystophorous cercariae from retusa obtusa (montagu) (gastropoda, opisthobranchia, retusidae) develop into adults of brachyphallus crenatus (rudolphi, 1802) odhner, 1905 (hemiuridae). the free-swimming cercariae were ingested by laboratory-reared acartia tonsa dana, and the cercarial body was injected into the hemocoel of the copepod. two-week-old metacercariae held at 15 c were infective to stickleback gasterosteus aculeatus linnaeus. the cercariae of b. crenatus are very similar to the cercaria ... | 1992 | 1556648 |
| helminth parasites of the chub mackerel scomber colias off the tunisian coast and their use in stock discrimination. | nine helminth parasites were used as biological tags to discriminate diverse areas of scomber colias gmelin, 1789. during three seasons, a total of 369 fish were examined in four zones off the tunisian coast, including bizerte in the north, kelibia and mahdia in the centre and zarzis in the south. discriminant analyses were used to identify distinct areas of s. colias. fish from bizerte were grouped as one area and were correlated negatively with the monogenean grubea cochlear and the digenean l ... | 2017 | 28215202 |
