The wageneri species group of Gyrodactylus contains the following molecularly confirmed salmonid parasites in Asia: taimeni Ergens, 1971, magnus Konovalov, 1967, brachymystacis 1978, and derjavini Mikhailov, 1975; Europe it following: derjavinoides Malmberg, Collins, Cunningham, Jalali, 2007, truttae Gläser, 1974, teuchis Lautraite, Blanc, Thiery, Daniel, Vigneulle, 1999, lavareti 1956, salveli...

  The present studywas carried out to survey ectoparasites fauna of gold fish (Carassius auratus) in Mazandaran province (Iran) from April 2009 to March 2010. A total of 200 samples were obtained from 10 ornamental fish supply centers and transferred alive to the laboratory. In this study, the following ectoparasites were isolated: Ichthyophthirius multifillis , Trichodina spp., Gyrodactyl...

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...

Various anthelmintics belonging to different pharmacological groups (ivermectin, clorsulon, closantel, netobimin, febantel, praziquantel, niclofolan, bithionol, trichlorfon, levamisole hydrochloride, piperazine citrate and dihydrochloride, nitroscanate), all of proven efficacy against certain helminths, were tested and compared for their in vivo and in vitro activity on a natural infection of O...

The ectoparasitic Monogenea comprise a major part of the obligate parasitic flatworm diversity. Although genomic adaptations to parasitism have been studied in the endoparasitic tapeworms (Cestoda) and flukes (Trematoda), no representative of the Monogenea has been investigated yet. We present the high-quality draft genome of Gyrodactylus salaris, an economically important monogenean ectoparasi...

BACKGROUND Gyrodactylus salaris is a monogenean, which has collapsed tens of wild Atlantic salmon populations. One of the means of preventing the spread of the parasite is the disinfection of the fishing equipment, which is used in the rivers having susceptible salmon populations. Little is known about the dosage of disinfectants against G. salaris. There are not standards for the testing of di...
