molecular characterization of anisakid nematode larvae from 13 species of fish from western australia.this study characterized anisakid nematodes in estuarine and near-shore species of fish in southern western australia. a total of 108 fish representing 13 species were examined for anisakid larvae. for the molecular characterization of anisakid larvae (n=218), we used pcr-coupled mutation scanning-sequencing-phylogenetic analyses of sequence variation in the internal transcribed spacers of nuclear ribosomal dna. with the exception of sillaginoides punctatus and sillago schomburgkii, all the fish ...201223353682
trace elements in sediments, blue spotted tilapia oreochromis leucostictus (trewavas, 1933) and its parasite contracaecum multipapillatum from lake naivasha, kenya, including a comprehensive health risk analysis.this study presents the distribution of 15 major and trace elements in sediments and fish and their pericardial parasites from lake naivasha, kenya. the lake is one of the few freshwater lakes in the great rift valley and is under strong anthropogenic pressure mainly due to agricultural activities. its fish provide a valuable protein source for approximately 100,000 people in the area. fish and their parasites have been acknowledged as indicators of environmental quality due to their accumulatio ...201424573461
epicutaneous sensitization with nematode antigens of fish parasites results in the production of specific igg and consumption plays an important role in the human diet. hoplias malabaricus, trahira, is a freshwater fish widely appreciated in several brazilian states and it is frequently infected by contracaecum multipapillatum third-instar larvae (l3). the aim of the present study was to evaluate the allergenic potential of the c. multipapillatum l3 crude extract (cecm). balb/c mice were immunized intraperitoneally (ip) with 10 or 50 μg cecm associated with 2 mg of aluminium hydroxide on days 0, 14 and ...201728780914
early development and life cycle of contracaecum multipapillatum s.l. from a brown pelican pelecanus occidentalis in the gulf of california, mexico.the initial developmental stages of contracaecum multipapillatum (von drasche, 1882) lucker, 1941 sensu lato were studied using eggs obtained from the uteri of female nematodes (genetically identified) found in a brown pelican pelecanus occidentalis from bahía de la paz (gulf of california, mexico). optical microscopy revealed a smooth or slightly rough surface to the eggs. egg dimensions were approximately 53 × 43 µm, although after the larvae had developed inside, egg size increased to 66 × 55 ...201728792415

contracaecum pyripapillatum n. sp. (nematoda: anisakidae) and a description of c. multipapillatum (von drasche, 1882) from the australian pelican, pelecanus conspicillatus.a new species of nematode, contracaecum pyripapillatum, is reported from the australian pelican, pelecanus conspicillatus. this species resembles contracaecum multipapillatum which was found in the same host. these two species can be differentiated from one another based on the shape of the preanal papillae, being pyriform in c. pyripapillatum and circular in c. multipapillatum. genetically, the two species differ in the sequences of first and second internal transcribed spacers (its-1 and its-2 ...200818688647
contracaecum multipapillatum (nematoda: anisakidae) from egretta alba (aves: ardeidae) and comments on other species of this genus in argentina.during a parasitological survey of aquatic birds in mar chiquita coastal lagoon (buenos aires province, argentina), specimens of contracaecum raillet & henry, 1912 sp. were found in the esophagus and stomach of the great egret egretta alba (gmelin, 1789) (aves: ardeidae). the nematodes were identified as contracaecum multipapillatum (drasche, 1882) on the basis of the following features: ratio of ventricular appendage length to esophagus length, ratio of intestinal caecum length to esophagus len ...200010958460
