A genus of the family REOVIRIDAE infecting vertebrates only. Transmission is horizontal and infected species include humans, birds, cattle, monkeys, sheep, swine, baboons, and bats. MAMMALIAN ORTHOREOVIRUS is the type species.

A species of ORTHOREOVIRUS infecting mammals (other than baboons). There are four serotypes. In humans they are generally benign but may sometimes cause upper respiratory tract illness or enteritis in infants and children. MAMMALIAN ORTHOREOVIRUS 3 is a very pathogenic virus in laboratory rodents.

A species of ORTHOREOVIRUS infecting birds, with outcomes ranging from inapparent to lethal depending on the virus strain and age of the host bird. This species does not infect mammals.

Infections produced by reoviruses, general or unspecified.

A family of snakes comprising the boas, anacondas, and pythons. They occupy a variety of habitats through the tropics and subtropics and are arboreal, aquatic or fossorial (burrowing). Some are oviparous, others ovoviviparous. Contrary to popular opinion, they do not crush the bones of their victims: their coils exert enough pressure to stop a prey's breathing, thus suffocating it. There are five subfamilies: Boinae, Bolyerinae, Erycinae, Pythoninae, and Tropidophiinae. (Goin, Goin, and Zug, Introduction to Herpetology, 3d ed, p315-320)

A family of unenveloped RNA viruses with cubic symmetry. The twelve genera include ORTHOREOVIRUS; ORBIVIRUS; COLTIVIRUS; ROTAVIRUS; Aquareovirus, Cypovirus, Phytoreovirus, Fijivirus, Seadornavirus, Idnoreovirus, Mycoreovirus, and Oryzavirus.

The complete genetic complement contained in a DNA or RNA molecule in a virus.

The relationships of groups of organisms as reflected by their genetic makeup.

A serotype of ORTHOREOVIRUS, MAMMALIAN causing serious pathology in laboratory rodents, characterized by diarrhea, oily coat, jaundice, and multiple organ involvement.

Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.

The degree of similarity between sequences of amino acids. This information is useful for the analyzing genetic relatedness of proteins and species.

The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.

Ribonucleic acid that makes up the genetic material of viruses.

Warm-blooded vertebrate animals belonging to the class Mammalia, including all that possess hair and suckle their young.
