as new pathogenic strains are emerging and threatening aquaculture development, myxosporeans (myxozoa) are receiving much attention in recent years. myxosporean taxonomy is traditionally based on morphology of the myxospore stage. molecular data on indian myxosporeans are rare. in this report, the 18s rrna gene sequence of myxobolus cuttacki infecting gill lamellae of minor carp labeo bata (ham...

As new pathogenic strains are emerging and threatening aquaculture development, myxosporeans (Myxozoa) are receiving much attention in recent years. Myxosporean taxonomy is traditionally based on morphology of the myxospore stage. Molecular data on Indian myxosporeans are rare.

A new species of sphaerosporid myxosporean, Sphaerospora elwhaiensis sp. n., is described from kidney of non-anadromous sockeye salmon (kokanee) Oncorhynchus nerka (Walbaum) from Lake Sutherland in the northern Olympic Peninsula, Washington, USA. Infection with the parasite was detected in 45% of 177 kokanee examined over 5 years. While conforming to the morphological criteria by which members ...

In India, more than 104 species of Myxobolus have so far been reported infecting freshwater as well as marine fishes. The study focuses on the description of a new myxosporean species, Myxobolus sp.n PKB 2014 from the gill lamellae of an Indian major carp Labeo rohita. The species have been described on the basis of morphological characterization of the spores, tissue architecture and 18S rDNA ...

Merced River Hatchery (MRH) juvenile Chinook salmon, from tagged lots used in the 2005 Vernalis Adaptive Management Program (VAMP) study, were brought to the California-Nevada Fish Health Center wet lab 6 days prior to the first VAMP release and reared for 50 days at water temperatures similar to the San Joaquin River. At the time of transport, a fish health inspection showed that the populatio...

The aim of the present work was to investigate the transcriptome response of gilthead sea bream (Sparus aurata) after challenge with the myxosporean Enteromyxum leei, a wide-spread enteric parasite causing heavy economic losses in Mediterranean sparid farms. This parasite causes severe desquamative enteritis which usually leads to death of the fish, and there are no preventative or curative tre...

Ceratomyxa shasta is a virulent myxosporean parasite of salmon and trout in the Pacific Northwest of North America. The parasite is endemic in the Klamath River, Oregon/California, where a series of dams prevent movement of fish hosts between the upper and lower parts of the basin. Ceratomyxa shasta exhibits a range of infection patterns in different fish species above and below the dams. We hy...
