Myxobolus cerebralis caused severe declines in rainbow trout populations across Colorado following its introduction in the 1980s. One promising approach for the recovery of Colorado's rainbow trout populations has been the production of rainbow trout that are genetically resistant to the parasite. We introduced one of these resistant crosses, known as the GR×CRR (cross between the German Rainbo...

This analysis of the introduction of racial theories to Brazil and their reception by Brazilian intellectuals in the late nineteenth/early twentieth centuries looks at miscegenation, racism, and whitening policies through the lenses of two novels that bear witness to the era's mentality: O cortiço (1890; A Brazilian tenement, 1976), by Aluísio Azevedo, and Canaã (1902; Canaan, 1920), by Graça A...

In Tunisia, mugilid and soleid fish species are among the most important resources of the Tunisian lagoons. These fish are of great economic value and they are highly valued for their flesh. Some species of mullet from Tunisian waters, especially Mugil cephalus and Liza ramada, have been found to be infected with several myxosporean species, all of which belonging to the genus Myxobolus Bütschl...

myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. the classification of myxosporeans is generally based on the morphology of their myxospores. without molecular data, it is very difficult to identify new or existing species. dna sequence information is therefore, a prerequisite to taxonomic and phy...

The infection with Myxobolus intimus Zaika, 1965 in the gills of the roach Rutilus rutilus (L.) from Lake Balaton was recorded in 28 out of the 39 fish examined. Developing and mature plasmodia were detected on the gills exclusively in the spring. The Myxobolus intimus infection was found only in 2- to 3-year-old fish. In histological sections, young plasmodia were found in capillaries of the s...

Myxobolus filamentum sp. n. was found infecting gill filaments of three of 39 Brycon orthotaenia Günther specimens examined (8%), which were taken from the river São Francisco in Minas Gerais state, Brazil. Plasmodia of the parasite were white and long, measuring 5 mm in lenght. Mature spores of M. filamentum sp. n. were oval from the frontal view and biconvex from the lateral view, measuring 7...

Archived tissues from affected yellow perch Perca flavescens, as well as fresh submissions of juvenile yellow perch, walleye, fathead minnows, golden shiners and smallmouth bass cultured in the same pond or from a shared water source were examined for the presence of Myxobolus neurophilus. Archived tissues were sectioned and stained with hematoxylin and eosin or with Giemsa, revealing myxozoan ...

The original description of Myxobolus longisporus Nie et Li, 1992, the species infecting gills of Cyprinus carpio haematopterus L., is supplemented with new data on the spore morphology and pathogenicity. Spores are elongate pyriform with pointed anterior end, 15.7 (15.5-16.5) microm long, 6.7 (6-8) microm wide and 5.5 microm thick. Sutural ridge is straight and narrow. Mucus envelope is lackin...
