Taxonomic Re-description and Molecular Characterization of Thelohanellus bifurcata Basu and Haldar, (1999) (Myxosporea: Myxobolidae) Using 18S rRNA Gene Sequences, Infecting the Gill Lamellae of Labeo rohita (Hamilton, 1822) from Ranaghat, West Bengal, India

Uttar Pradesh Journal of Zoology
Myxozoans have been classified into 62 genera having more than 2600 species all over the world. Among these genus Thelohanellus Kudo, 1933 is the second largest genus after Myxobolus.

Host Cell Hypertrophy Induced by Contact with Trophozoites of Thelohanellus pyriformis (Myxozoa: Myxosporea)

Archiv für Protistenkunde, 1987
Summary Thelohanellus pyriformis ( Thelohan 1892) from tench (Tinca tinca) gills is redescribed using light and electron microscopy. Trophozoites in form of polysporic plasmodia develop in gill filament arteries. The plasmodia are coated with endothelial cells of the host.

The phylogenetic study on Thelohanellus species (Myxosporea) in relation to host specificity and infection site tropism.

Molecular Phylogenetics and Evolution, 2014
Thelohanellus kitauei (Myxobolidae) infects cyprinid fish. The evolution of species derived from common ancestors results in the sharing of biological features. To reveal the origin of T. kitauei biological features, the correlation between phylogeny and biological features of Myxobolidae was investigated by Bayesian inference tree and Bayesian tip ...

Low pH, dissolved oxygen and high temperature induces Thelohanellus rohita (myxozoan) infestation in tropical fish, Labeo rohita (Hamilton) [PDF]

Journal of Parasitic Diseases, 2012
In Labeo rohita, myxozoan infection is very common and here occurrence and distribution of myxozoan gill parasites were studied with an objective to evaluate the relationship between myxozoan infections with different abiotic factors. All ponds were infected with myxozoan infection.

Molecular and phylogenetic characterization of Thelohanellus boggoti Qadri, 1962 (Cnidaria, Myxosporea, Bivalvulida) infecting the fin of Indian minor carp Labeo dero (Hamilton, 1822)

Molecular Biology Research Communications, 2017
A myxozoan parasite belonging to the genus Thelohanellus Kudo, 1933 (Cnidaria, Myxosporea, Bivalvulida) was isolated from the fins of Labeo dero inhabiting Ranjit Sagar Wetland, Punjab, India. The plasmodium was 0.5-0.7 mm in diameter each containing 80-

Thelohanellus toyamai (Syn. Myxobolus toyamai) Infecting the Gills of Koi Cyprinus carpio in the Eastern United States

Journal of Parasitology, 2011
A myxozoan resembling species of Thelohanellus was isolated from the gills of koi (Cyprinus carpio) cultured in North Carolina. Plasmodia measuring ∼200 µm in diameter contained tear-shaped myxospores containing a single pyriform polar capsule. The spore body was concave on one side, measuring 16.2 (14.7-16.8) µm long and 5.6 (4.5-6) µm wide. The polar

First molecular evidence of Thelohanellus wallagoi Sarkar, 1985 (Myxozoa) from economically important food fish, freshwater shark Wallago attu (Siluridae) in India

Acta Parasitologica, 2018
The freshwater shark Wallago attu (Bl. and Schn.) is a frequent silurid in the River Ganga and one of the most commercially exploit fish in India. In a survey on its infection with myxosporeans, spore type belongs to Thelohanellus species was found in ...

Surgical removal of an anal cyst caused by a protozoan parasite (Thelohanellus kitauei) from a koi (Cyprinus carpio)

Journal of the American Veterinary Medical Association, 2011
Abstract Case Description—An 8-month-old koi (Cyprinus carpio) fish was examined at the animal hospital at Seoul National University for anal obstruction. Clinical Findings—The affected fish was lethargic and anorexic, appeared depressed, and had a nodular obstruction at the anus.

[The biology and pathogenicity of the carp parasite Thelohanellus nikolskii (Myxosporidia)].

Parazitologiia, 1991
The myxosporidian Thelohanellus nikolskii has been recorded in young of carp in fish-breeding ponds of Moldavia since 1982. Sporogenesis takes place from June to August. Single cysts with mature spores are found in winter and spring. The distribution of cysts in the host's population is of overdispersed character.
