Cryptobia cataractae from the Blood of Semotilus atromaculatus: Structure and Division in the Fish
The Journal of Parasitology, 1990A cryptobiid was found in the blood of 2 of 9 Semotilus atromaculatus from a tributary of the Saugeen River in Ontario, Canada. Blood inoculation produced an infection in 2 uninfected S. atromaculatus but not in any Oncorhynchus mykiss, Catostomus commersoni, or Carassius auratus.

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)

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.

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 ...

Effects of the pathogenic haemoflagellate, Cryptobia salmositica on brood fish, Oncorhynchus mykiss
Environmental Biology of Fishes, 2008Sexually matured rainbow trout, Oncorhynchus mykiss, were experimentally infected with the pathogenic Cryptobia salmositica. Spawning female trout were more susceptible to cryptobiosis than sexually mature males. Most infected females (seven of nine) with eggs died before or shortly after spawning while all (nine) infected males survived the disease ...

PATHOLOGY ASSOCIATED WITH Cryptobia INFECTION IN A SUMMER FLOUNDER (Paralichthys dentatus)
Journal of Wildlife Diseases, 1978A laboratory-held summer flounder (Paralichthys dentatus) became moribund and presented gross ulcerative and hemorrhagic lesions, concomitant with a space-occupying lesion in the abdominal cavity and a prolapsed rectum. Edema, hemorrhage, and necrosis of the intestine and edema of the stomach wall were noted upon post-mortem examination.

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).

A cathepsin L-like cysteine proteinase gene from the protozoan parasite, Cryptobia salmositica
Parasitology Research, 2006The present study describes the identification of a cathepsin L-like cysteine proteinase gene (CYS) from the hemoflagellate Cryptobia salmositica. Genomic DNA sequence of cysteine proteinase was obtained by genome walking using degenerate primers. Specific primers were designed to amplify the cDNA of cysteine proteinase from mRNA by rapid amplification

A New Hemoflagellate (Genus Cryptobia) from Marine Fishes of Northern New England
The Journal of Parasitology, 1965A new species of hemoflagellate is described from the blood of marine fishes of northern New England. This appears to be the first record of a biflagellate organism in the blood of marine fishes from the Western Hemisphere. The parasite, placed in the genus Cryptobia Leidy (Trypanoplasma, Laveran and Mesnil), differs morphologically from Trypanoplasma ...

The Flagellate Cryptobia in Two Species of Deepsea Fishes from the Eastern Pacific
The Journal of Parasitology, 1968Since 1888, eight species of Cryptobia (= Trypanoplasma) have been described or mentioned from marine fishes. The present paper describes two new species: C. stilbia, from the stomach of Bathylagus stilbius, a mesopelagic fish from the coast of California, and C.
