Species of the monogenean genus Thaparocleidus are specific to freshwater siluriform fish. The infection caused by these gill parasites are a major health problem to fish. But, to focus the control strategies of these parasites, first it is important to establish an accurate discrimination by molecular methods. In the present study, phylogenetic and structural analysis of 28S region of ribosoma...

background: this study was conducted to collect informative data on the parasitic infection of wild rodents, emphasizing on finding parasites, which have medical importance to human. methods:   during 2012-2014, a total number of 91 wild rodents were captured from rural areas of turkmen sahra, golestan province, using handmade traps. animals were anesthetized, surveyed for any ectoparasite and ...

This study reports for the first time the monogenean Palombitrema triangulum Suriano (1981) in freshwater fishes from Brazil, highlighting new sites of infection for this helminth and some morphological differences. Monogeneans were collected on the body surface, gills and nasal cavity of two native fish species from Brazil, Cyphocharax modestus (Fernández-Yépez, 1948) and Cyphocharax nagelii (...

We present the complete mitochondrial (mt) genome of Gyrodactylus thymalli, a monogenean ectoparasite on grayling (Thymallus thymallus). The circular genome is 14788 bp in size and includes all 35 genes recognized from other flatworm mt genomes. The overall A+T content of the mt genome is 62.8%. Twenty regions of non-coding DNA ranging from 1 to 111 bp in length were identified in addition to 2...

twenty four ecto- and endo- parasite species were found in different organs of eight na-tive and exotic fish species in zarivar lake situated in the far west of iran. overall, 1000 fish specimens belonging to the dactylogyridae, gyrodactylidae families the cyprinidae, poeciliidae and mastacembelidae families were examined during 2001 and 2002. of them, five protozoans, including trichodina pedi...

backgrounds: gyrodactylus is a small monogenean ectoparasite that lives on the skin and fins of most of the world's fish species. gyrodactylus appears to be one of the most prevalent parasites found in ornamental fish, especially in cyprinids. goldfish (carassius auratus) are a popular ornamental fish that are highly contaminated by gyrodcatylus. objectives: the present study is aimed to identi...

the purpose of this study was to investigate the status and epidemiology of intestinal parasites in iran. the information was driven from an extensive health survey which was done by the ministry of health and medical education, deputy of research affairs in 1990-92. sampling fraction was 1 per 1000 of individuals aged between 2 and 69, the sampling method was cluster sampling and each cluster ...
