Literature review of reports concerning the parasitic fauna floating cage fishes in Iraq till end 2021 showed that a total 57 parasite species are so far known from three fish investigated for infections throughout country. The included 15 ciliophorans, myxozoans, two trematodes, 28 monogeneans, five cestodes, one nematode, acanthocephalan and crustaceans. common carp Cyprinus carpio was infect...
May 2005 1867 ABSTRACT A coprological survey was made to assess the spectrum of helminth parasites in Mithun and other co-existing wild livestock in Bhutan and neighbouring Arunachal Pradesh (India). Nematodes with direct life cycle were found to be most predominant helminth infection among these animals. Cestodes and trematodes were poorly represented as their occurrence is primarily determine...
Pesticides can elevate trematode infections in amphibians. However, direct adverse effects of pesticides on embryos and free-living stages of trematodes have not been thoroughly explored, despite the potential for these effects to reduce amphibian trematode infections. We measured the effects of atrazine, glyphosate, carbaryl, and malathion on embryo and miracidium (free-living stage) survival ...
Seven dolphins (Delphinus sp.) that were found stranded near Point Mugu, California between 1966 and 1970 were given complete necropsy examinations. In all seven cases a similar pathological picture was observed. The findings included adult trematodes in the bile and pancreatic ducts, severe liver damage, and massive brain necrosis due to the presence of numerous trematode ova in the brain tiss...
We isolated and characterized 11 microsatellite loci from Plagioporus shawi , a parasitic trematode of salmonid fishes ( Oncorhynchus spp.). Extensive polymorphism (expected heterozygosities ranging from 0.476 to 0.981 and number of alleles from 10 to 55) was found in a sample of 94 trematodes from 24 infected cutthroat trout ( Oncorhynchus clarki ) individuals. Nine of the 11 loci will be usef...
Nine species of nematodes, unidentified larval nematodes, three species of trematodes, two species of acanthocephalans and a single species of chewing louse were collected from 1993 to 1995 from 25 introduced whooping cranes (Grus americana) in Florida (USA). In spite of a quarantine procedure involving anthelmintic therapy, three helminth parasites may have been introduced from captive populat...
in this survey, 54 specimens of common carp (cyprinus carpio) were collected from anzali wetland between august 2011 and july 2012. after recording biometric characteristics, routine necropsy and parasitology methods were used. totaly, 3165 individuals of parasites were isolated and identified from common carp. parasitofauna consisted of 10 species as follows: two protozoans, ichthyophthirius m...
The purpose of the research is morphological and molecular identification trematodes found in intestines migratory waterfowl with subsequent taxonomic evaluation. Materials methods . Mature specimens were collected from ( Fulica atra Aythya ferina ) shot during ecological-faunistic monitoring southern part Primorsky krai. Preliminary analyze revealed that belong to Echinostomatidae family. whol...
The Boojagh international wetland with a surface area of 80 hectares and 25 fish species is located in the southwest shores of the Caspian Sea (Guilan province, Iran), but there is no report about fish parasites in this wetland. In the present study, a total of 553 individuals of 8 fish species including Cyprinus carpio (n=71), Abramis bjoerkna (n=153), Carassius auratus gibelio (n=89), Esox...
