Proliferative kidney disease in brown trout Salmo trutta: further evidence of a myxosporean aetiology

Two groups of brown trout Salmo trutta L. were studied, one after natural exposure to PKD-infected waters, the other after laboratory challenge by intraperitoneal inoculation with PKDinfected kidney tissue from rainbow trout Salmo gairdneri Richardson. Subclinical PKD developed in both groups; renal intraluminal myxosporean organisms were observed in both groups. The implications of these findi...

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...

Myxosporean parasites in Australian frogs: Importance, implications and future directions

Myxosporean parasites have been identified in amphibians around the world yet very little is known about their diversity, biology and host impact. Several species of Australian frogs have recently been shown to be affected by myxosporidiosis caused by two new Cystodiscus species. In this manuscript, we review what is known about the myxosporean parasites Cystodiscus australis and Cystodiscus ax...

Can myxosporean parasites compromise fish and amphibian reproduction?

Research into fish and amphibian reproduction has increased exponentially in recent years owing to the expansion of the aquaculture industry, the need to recover fishery populations, the impact of endocrine disruptors on the aquatic environment and the global decline of amphibian populations. This review focuses on a group of parasites, the Myxozoa, that affect fish and amphibian reproduction. ...
