Glucocorticoid receptors on and in a unicellular organism, Cryptobia salmositica
International Journal for Parasitology, 2014This is the first report to our knowledge that demonstrates a functional steroid hormone receptor in a protozoon. The study used Cryptobia salmositica, a pathogenic haemoflagellate found in salmonid fishes. It has been previously shown that cortisol and dexamethasone (a synthetic glucocorticoid) enhanced the multiplication of C.

Improved Culture Media for Piscine Hemoflagellates, Cryptobia and Trypanosoma (Kinetoplastida)
The Journal of Parasitology, 1998Increasing the Hepes buffer in minimum essential medium from 25 mM to 100 mM yielded a significantly larger number of Cryptobia salmositica. Cryptobia salmositica (pathogenic and nonpathogenic strains), Cryptobia bullocki, and Trypanosoma danilewskyi did not multiply either in heat-inactivated trout plasma (< or =25%) or in less than 10% fresh trout ...

A metalloproteinase gene from the pathogenic piscine hemoflagellate, Cryptobia salmositica
Parasitology Research, 2006We report the identification of a Cryptobia genomic DNA gene predicted to encode a hydrophobic protein containing a zinc metalloproteinase motif, HEXXH, and hence named it a major surface proteinase 1-like (MSP-1). The MSP-1 gene was identified using universal genome walking. Southern blot analysis revealed it to be a multicopy gene.

Acid Phosphatase in the Pathogenic and Nonpathogenic Hemoflagellates, Cryptobia spp., of Fishes
The Journal of Parasitology, 1996Acid phosphatase (ACP) was detected in whole-cell lysates, membrane-bound and water-soluble fractions of Cryptobia salmositica (pathogenic and nonpathogenic vaccine strains), Cryptobia bullocki, and Cryptobia catostomi using p-nitro-phenylphosphate as the substrate.

Protection against Cryptobia (Trypanoplasma) salmositica and Salmonid Cryptobiosis
Parasitology Today, 1998Cryptobia (Trypanoplasma) salmositica is a haemoflagellate that causes morbidity and mortality in salmon, Oncorhynchus spp, on the Pacific coast of North America. In this review, Patrick Woo briefly describes the pathogen, its transmissions (either indirectly via its leech vector, Piscicola salmositica, or directly between fish) and the clinical signs ...

The Journal of Parasitology, 1986
Using the sealed jar technique (also called residual oxygen bioassay), rainbow trout fry infected with Cryptobia salmositica were more susceptible than non-infected fish to environmental hypoxia. The Winkler technique (azide modification) was used to determine the residual dissolved oxygen in the water. Susceptibility of infected fish increased with 1)

Cryptobia and Cryptobiosis in Fishes
1987Publisher Summary Cryptobia is a flagellate with two flagella (one being attached to the body), a prominent kinetoplast, and a nucleus. The parasite has been reported on the body surface, in the digestive tract, and in the blood of fishes. The chapter helps to unify and clarify the relationship among the various groups of cryptobia and, as a result ...

Cryptobia (Trypanoplasma) salmositica and salmonid cryptobiosis
Journal of Fish Diseases, 2003AbstractSalmonid cryptobiosis is caused by Cryptobia (Trypanoplasma) salmositica. The haemoflagellate has been reported from all species of Pacific Oncorhynchus spp. on the west coast of North America. It is normally transmitted by the freshwater leech, Piscicola salmositica, in streams and rivers, and sculpins, Cottus spp., are considered important ...

Parasitology Research, 2007
We report on the identification of a Cryptobia genomic DNA gene, predict it to encode a S-adenosylmethionine synthetase signature 1 motif and propose to name it S-adenosylmethionine synthetase (MAT). The open reading frame of MAT is 1,046 bp with 341 deduced amino acids.

Towards a metalloprotease-DNA vaccine against piscine cryptobiosis caused by Cryptobia salmositica
Parasitology Research, 2007Cysteine protease is a metabolic enzyme, whereas metalloprotease is the virulent factor in cryptobiosis caused by Cryptobia salmositica. Recombinant DNA vaccines were produced with the insertion of either the metalloprotease or cysteine protease gene of C. salmositica into plasmid vectors (pEGFP-N).
