The aim of the study was to develop a data base about the water quality in the Lake of 16 Tishreen Dam through, study was performed to determine of non biotic factors values of water in Lake and infecting FreeLiving fishes with monogenea parasites, and finding a relationship between parasites distribution and environmental conditions changing. 144 Free – living fishes were examined for detectin...

Recent studies on microRNA (miRNA) evolution focused mainly on the comparison of miRNA complements between animal clades. However, evolution of miRNAs within such groups is poorly explored despite the availability of comparable data that in some cases lack only a few key taxa. For flatworms (Platyhelminthes), miRNA complements are available for some free-living flatworms and all major parasitic...

We recorded the parasitic fauna of Hoplias malabaricus in a Neotropical River from southeastern Brazil, Jacaré-Pepira River, Tietê-Batalha Basin. The objective this study was to inventory composition H. collected, through ecological and biodiversity approaches. A total 30 specimens were collected 2018 using fishing nets. Parasites prevalent 96.6% hosts, with 710 parasites divided into 22 specie...

Abstract The present study investigated the metazoan parasite community in Pimelodus ornatus from Amazon River, state of Amapá (Brazil). Of 71 fish examined, 70.4% were parasitized by Demidospermus sp. (Monogenea), Cucullanus pinnai, Procamallanus (Spirocamallanus) inopinatus and Contracaecum (Nematoda) plerocercoids Proteocephalidae gen. (Cestoda). dominance was nematode species such as (S.) p...

Die wêreldwye indringerpadda, die gewone platanna Xenopus laevis (Anura: Pipidae), toon duidelike filogeografiese verskille tussen sy verskillende bevolkings in suidelike Afrika, natuurlike gebied. Dit het direk tot hoë genetiese variasie sommige van indringerbevolkings bygedra. Nietemin is daar nog geen sekerheid oor hoe stamme gebied met mekaar verband hou nie. Daarbenewens en geografi ese ve...

During the present investigation, 23 species of fish in Lithuanian inner waters were examined for helminth parasites. Of these, 63 taxa helminths – 56 Plathyhelminthes, five Nematoda, and two Acanthocephales found. Monogenea Gyrodactylus truttae was registered Lithuania first time. Metacercariae flukes Diplostomum sp., Posthodiplostomum cuticula, Tylodelphys clavata found highest number host sp...

Thirty three Gyrodactylus spp have been found on the gills and body surface of both wild and farmed freshwater fishes in Iran. Among them nine species have been identified up to the species level, which are new locality records. The identification of the others, mainly belong to endemic wild freshwater fishes, need further studies. Among the known species, Gyrodactylus derjavini (Mikhailov, 197...
