Molecular evidence that the proliferative kidney disease organism unknown (PKX) is a myxosporean.
The proliferative kidney organism unknown (PKX), a serious salmonid fish pathogen, is considered to be a myxosporean on the basis of ultrastructural studies, but its real taxonomic position has never been confirmed. In order to ascertain its position, genomic DNA was extracted from PKX and small subunit (SSU) ribosomal DNA was amplified by PCR, cloned and sequenced. A phylogenetical analysis on...
متن کاملNON-SALMONID FISH INHABITING A HATCHERY WATER SUP- PLY ENZOOTIC FOR PROLIFERATIVE KIDNEY DISEASE IN- FECTED WITH ONE MYXOSPOREAN, Myxobilatus SP'P
Proliferative kidney disease (PKD), caused by an unclassified myxosporean (PKX), is a serious disease of salmonids. Although partial spore development occurs to a limited extent in fish infected with PKX, complete sporalation has not been observed and precise taxonomic status of PKX remains uncertain. The severe inflammation seen in infected fish, unusual for most myxosporean infections, sugges...
متن کاملProliferative kidney disease in rainbow trout: time- and temperature-related renal pathology and parasite distribution.
Proliferative kidney disease is a parasitic infection of salmonid fishes caused by Tetracapsuloides bryosalmonae. The main target organ of the parasite in the fish is the kidney. To investigate the influence of water temperature on the disease in fish, rainbow trout Oncorhynchus mykiss infected with T bryosalmonae were kept at 12 degrees C and 18 degrees C. The number of parasites, the type and...
متن کاملDisease problems of salmonid fish in Japan caused by international trade.
The author details the connection between disease outbreaks in salmonid fish and imports of salmonid eggs into Japan since the 1950s. The following diseases and species are involved: -infectious pancreatic necrosis in rainbow trout (Oncorhynchus mykiss) -infectious haematopoietic necrosis in sockeye ( of 'kokanee') salmon (O. nerka) and masu salmon (O. masu) -cold water disease, erythrocyte inc...
متن کاملLife cycle complexity, environmental change and the emerging status of salmonid proliferative kidney disease
1. Proliferative kidney disease (PKD) is a disease of salmonid fish caused by the endoparasitic myxozoan, Tetracapsuloides bryosalmonae, which uses freshwater bryozoans as primary hosts. Clinical PKD is characterised by a temperature-dependent proliferative and inflammatory response to parasite stages in the kidney. 2. Evidence that PKD is an emerging disease includes outbreaks in new regions, ...
