Ultramorphology and molecular studies of Contracaecum larvae (Nematoda: Anisakidae) collected in five Cyprinid fish species from Sulaimani Province, Kurdistan Region-Iraq

Short communication: Morphological and genetic characterisation of selected Contracaecum (Nematoda: Anisakidae) larvae in Iran

Experimental studies on the development of Contracaecum rudolphii (Nematoda: Anisakidae) in copepod and fish paratenic hosts.

The larval development of the nematode Contracaecum rudolphii (Rudolphi, 1819), a common parasite of the proventriculus of cormorants, was experimentally studied. Within the eggs cultivated in freshwater under laboratory temperatures of 20-22 degrees C, the developing larva undergoes two moults on days 4-5, attaining the third larval stage. Most of the ensheathed third-stage larvae, 291-457 mic...

First record of Contracaecum spp. (Nematoda: Anisakidae) in fish-eating birds from Zimbabwe.

Endoparasites of fish-eating birds, Phalacrocorax africanus, P. carbo, Anhinga melanogaster and Ardea cinerea collected from Lake Chivero near Harare, Zimbabwe, were investigated. Adult Contracaecum spp. were found in the gastrointestinal tract (prevalence 100 % in P. africanus, P. carbo and A. melanogaster; 25 % in A. cinerea). Parasite intensity was 11-24 (mean 19) in P. africanus, 4-10 (mean...

The occurrence of Contracaecum sp. larvae (Nematoda: Anisakidae) in the catfish Clarias gariepinus (Burchell) from Lake Chivero, Zimbabwe.

Clarias gariepinus were collected from Lake Chivero, Zimbabwe, and examined for nematode parasites from November 2000 to May 2002. Of the 202 specimens collected, 42.6% were infected with third-stage larvae of Contracaecum sp. in the body cavity. The intensity of the infection was 1-7 worms per fish (mean intensity = 2.2). Seasonal variation in the prevalence of the parasite was not obvious and...
