Cryptobia iubilans Infections in Discus Fish in Trinidad and Tobago

Journal of Parasitology, 2020
Discus (Symphysodon spp.) are costly and prized specimens in the international ornamental fish trade. The majority of discus submitted to the Aquatic Animal Health Unit at the University of the West Indies School of Veterinary Medicine for necropsy between September 2010 and September 2015 had lesions consistent with Cryptobia iubilans infection, thus ...

Phylogenetic position of the kinetoplastids, Cryptobia bullocki, Cryptobia catostomi, and Cryptobia salmositica and monophyly of the genus Trypanosoma inferred from small subunit ribosomal RNA sequences

Molecular and Biochemical Parasitology, 1999
Phylogenetic relationships within the kinetoplastid flagellates were inferred from comparisons of small-subunit ribosomal RNA gene sequences. These included three new gene sequences from Cryptobia bullocki, (2091 bp), Cryptobia catostomi (2090 bp), and Cryptobia salmositica (2091 bp).

Glucocorticoid receptors on and in a unicellular organism, Cryptobia salmositica

International Journal for Parasitology, 2014
This 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.

An in vitro study on the mechanism of innate immunity in Cryptobia -resistant brook charr ( Salvelinus fontinalis ) against Cryptobia salmositica

Parasitology Research, 1996
Fresh plasma from Cryptobia-resistant brook charr (Salvelinus fontinalis) lysed Cryptobia salmositica under in vitro conditions. However, the parasite was not lysed if the plasma was heat-inactivated at 37 degrees C for 2 h or after the addition of ethylenediaminetetraacetic acid (EDTA) to chelate the free Mg2+ ions.

A metalloproteinase gene from the pathogenic piscine hemoflagellate, Cryptobia salmositica

Parasitology Research, 2006
We 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, 1996
Acid 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.

Improved Culture Media for Piscine Hemoflagellates, Cryptobia and Trypanosoma (Kinetoplastida)

The Journal of Parasitology, 1998
Increasing 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 ...

Transmission of the Hemoflagellate, Cryptobia salmositica Katz, 1951, by a Rhynchobdellid Vector

The Journal of Parasitology, 1965
The transmission of Cryptobia salmositica Katz, 1951, a hemoflagellate of freshwater teleosts, was investigated in experiments involving the rhynchobdellid leech, Piscicola salmositica Meyer, 1946. Uninfected leeches developed metacyclic stages of Cryptobia in their digestive tracts after feeding on naturally infected torrent sculpins (Cottus rhotheus).

Cryptobia and Cryptobiosis in Fishes

1987
Publisher 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 ...

In vitro Effects of Fetal Bovine Serum and Glucose on Multiplication of Cryptobia salmositica

The Journal of Parasitology, 1991
Cryptobia salmositica multiplied rapidly at 10 C in a minimum essential medium (containing 1.0 mg glucose/ml, Hanks' salts and L-glutamine) supplemented with heat-inactivated fetal bovine serum (FBS) and HEPES buffer (25 mM). The multiplication rate of C.
