Study investigates aquatic parasites on fish April 23,2012   |  Source: PhysOrg

Researchers in the Czech Republic, Spain and the United Kingdom have successfully identified the cellular components and mechanisms that play a role in the proliferation of myxozoa, tiny aquatic parasites responsible for diseases in commercially valuable fish. Presented in the journal PLoS ONE, the study's findings shed light on the motility of myxozoa's proliferative states and their reproductive process.

Produced through spores and without insemination, myxozoa are related to cnidarians, what researchers define as being primitive marine species of great diversity. Examples of myxozoa include anemones, corals and jellyfish. Fish quickly fall victim to these parasites because of the latter's fast proliferation. It should be noted, however, that research has failed to elucidate the consequences of their development.

Led by the Cavanilles Institute of Biodiversity and Evolutionary Biology at the University of Valencia in Spain, the researchers used confocal laser-scanning microscopy (CLSM) to probe the anatomy and reproductive biology of the pathogens.

For their part of the study, the Spanish team investigated the morphology, structure and composition of the myxozoa Ceratomyxa puntazzi, found in the bile of the bream Diplodus puntazzo. This bream is one of the species
