The largest genus in the family Myxobolidae, class MYXOSPOREA, containing over 400 species.

Infections with unicellular organisms formerly members of the subkingdom Protozoa. The infections may be experimental or veterinary.

A vegetative stage in the life cycle of sporozoan protozoa. It is characteristic of members of the phyla APICOMPLEXA and MICROSPORIDIA.

One of the three domains of life (the others being BACTERIA and ARCHAEA), also called Eukarya. These are organisms whose cells are enclosed in membranes and possess a nucleus. They comprise almost all multicellular and many unicellular organisms, and are traditionally divided into groups (sometimes called kingdoms) including ANIMALS; PLANTS; FUNGI; and various algae and other taxa that were previously part of the old kingdom Protista.

Infections or infestations with parasitic organisms. The infestation may be experimental or veterinary.

Diseases of freshwater, marine, hatchery or aquarium fish. This term includes diseases of both teleosts (true fish) and elasmobranchs (sharks, rays and skates).

Single-celled, aquatic endoparasitic worms that are currently considered belonging to the phylum CNIDARIA. They have a complex life cycle and parasitize a wide range of hosts including FISHES; ANNELIDA; and BRYOZOA.

A class of annelid worms with few setae per segment. It includes the earthworms such as Lumbricus and Eisenia.

Paired respiratory organs of fishes and some amphibians that are analogous to lungs. They are richly supplied with blood vessels by which oxygen and carbon dioxide are exchanged directly with the environment.

A family of freshwater fish comprising the minnows or CARPS.

Constituent of the 40S subunit of eukaryotic ribosomes. 18S rRNA is involved in the initiation of polypeptide synthesis in eukaryotes.

A large stout-bodied, sometimes anadromous, TROUT found in still and flowing waters of the Pacific coast from southern California to Alaska. It has a greenish back, a whitish belly, and pink, red, or lavender stripes on the sides, with usually a sprinkling of black dots. It is highly regarded as a sport and food fish. Its former name was Salmo gairdneri. The sea-run rainbow trouts are often called steelheads. Redband trouts refer to interior populations of rainbows.

The reproductive elements of lower organisms, such as BACTERIA; FUNGI; and cryptogamic plants.

Cultivation of natural faunal resources of water. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

A veterinary coccidiostat that interferes with THIAMINE metabolism.

A genus of the family SALMONIDAE (salmons and trouts). They are named for their hooked (onco) nose (rhynchus). They are usually anadromous and occasionally inhabit freshwater. They can be found in North Pacific coastal areas from Japan to California and adjacent parts of the Arctic Ocean. Salmon and trout are popular game and food fish. Various species figure heavily in genetic, metabolism, and hormone research.

Methods of preparing tissue for examination and study of the origin, structure, function, or pathology.

Thin-walled sacs or spaces which function as a part of the respiratory system in birds, fishes, insects, and mammals.

I'm sorry for any confusion, but "Hungary" is not a medical term; it is a country located in Central Europe, and its name should not be used in the context of medical definitions.

A group of cold-blooded, aquatic vertebrates having gills, fins, a cartilaginous or bony endoskeleton, and elongated bodies covered with scales.

Deoxyribonucleic acid that makes up the genetic material of protozoa.

Large natural streams of FRESH WATER formed by converging tributaries and which empty into a body of water (lake or ocean).

The continuous sequence of changes undergone by living organisms during the post-embryonic developmental process, such as metamorphosis in insects and amphibians. This includes the developmental stages of apicomplexans such as the malarial parasite, PLASMODIUM FALCIPARUM.

Common name for a number of different species of fish in the family Cyprinidae. This includes, among others, the common carp, crucian carp, grass carp, and silver carp.

I'm sorry for any confusion, but "Colorado" is a place, specifically a state in the United States, and does not have a medical definition. If you have any questions about medical conditions or terminology, I would be happy to help with those!

Environments or habitats at the interface between truly terrestrial ecosystems and truly aquatic systems making them different from each yet highly dependent on both. Adaptations to low soil oxygen characterize many wetland species.

DNA sequences encoding RIBOSOMAL RNA and the segments of DNA separating the individual ribosomal RNA genes, referred to as RIBOSOMAL SPACER DNA.

Water containing no significant amounts of salts, such as water from RIVERS and LAKES.
