Betaretrovirus Categories.

	Mammary Tumor Virus, Mouse - The type species of BETARETROVIRUS commonly latent in mice. It causes mammary adenocarcinoma in a genetically susceptible strain of mice when the appropriate hormonal influences operate.
	Mason-Pfizer monkey virus - A species of BETARETROVIRUS isolated from mammary carcinoma in rhesus monkeys. It appears to have evolved from a recombination between a murine B oncovirus and a primate C oncovirus related to the baboon endogenous virus. Several serologically distinct strains exist. MPMV induces simian AIDS (SAIDS).
	Ovine pulmonary adenocarcinoma virus - A BETARETROVIRUS that causes pulmonary adenomatosis in sheep (PULMONARY ADENOMATOSIS, OVINE).
