Tacaiuma virus (TCMV) A species in the genus Bunyavirus, belonging to the Anopheles A serogroup. Isolated from sentinel Cebus monkeys and mosquitoes in Para and Sao Paulo, Brazil. Not reported to cause disease in humans.

Tacaribe complex viruses

Tacaribe complex viruses A group of morphologically identical and serologically related viruses. Members of the New World group of the genus Arenavirus, named after the first one to be described: Tacaribe virus. Mostly transmitted by rodents.

Tacaribe virus (TACV) A species in the genus Arenavirus. One of the New World arenaviruses. Isolated from two species of Artibeus bats, A. lituratus and A. jamaicensis in Trinidad, and named after a pre-Colombian tribe of Trinidadian Indians. Has been recovered on one occasion from mosquitoes. A silent infection can be induced experimentally in the guinea pig. Not reported to cause disease in humans.

tadpole edema virus (TEV) A strain of Frog virus 3 in the genus Ranavirus. Isolated from Rana catesbiana.

Wolf K et al (1968) J Infect Dis 118, 253

tadpole virus 2 Synonym for Redwood Park virus, a tentative species in the genus Ranavirus.

Taggert virus (TAGV) A strain of Sakhalin virus in the genus Nairovirus. Isolated in suckling mice from nymphs of the tick, Ixodes uriae, collected in tussock grass and under planks on the shore near a rookery of the royal penguin, Eudyptes chrysolophus schlegeli, on Macquarie Island, 800 miles south-east of Tasmania. Antibodies were found by plaque reduction test in four of 31 penguin sera. Not reported to cause disease in humans.

Tahyna virus (TAHV) A strain of California encephalitis virus in the genus Bunyavirus, belonging to the California serogroup. Isolated in the former Czechoslovakia, Germany, former Yugoslavia, France and Italy. Can cause a febrile illness in humans. Serologically indistinguishable from Lumbo virus isolated in Mozambique.

Taiassui virus (TAIAV) A possible species in the genus Bunyavirus, belonging to the Bunyamwera virus serogroup. Isolated from a pool of Sabethini mosquitoes.

Tai virus (TAIV) An unassigned virus in the family Bunyaviridae. Isolated from Culiciomyia nebulosus in the Ivory Coast.

taka-diastase A crude preparation from the fungus, Aspergillus oryzae, which has a-amylase activity and from which several nucleases can be isolated, including ribonuclease T1, ribonuclease T2 and S1 nuclease.

Talfan disease virus Synonym for a porcine enterovirus. Talfan disease is a mild form of Teschen disease, first observed in Denmark and England in 1955-57.

Tamana bat virus (TABV) A tentative species in the genus Flavivirus, with no known vector.

Tamdy virus (TDYV) An unassigned virus in the family Bunyaviridae. Isolated from ticks, Hyalomma a. asiaticum and H. p. plumbeum, collected from humans working with sheep and camels in the desert regions of Turkmenistan and Uzbekistan. As these ticks parasitize rodents, hedgehogs, hares and birds, they may also be hosts for the virus. No antigenic relationship found to a range of viruses. Does not agglutinate goose erythrocytes. Pathogenic for suckling and 3-week-old mice on i.c. injection. Not reported to cause disease in humans.

Tamiami virus (TAMV) A species in the genus Arenavirus. One of the New World arenaviruses, belonging to the Tacaribe complex. Isolated from cotton rats, Sigmodon hispidus, in Florida, USA. Not reported to cause disease in humans.

Tamiflu Generic name oseltamivir. Drug effective against both A and B types of

Tax protein influenza. Acts by inhibiting influenza neuraminidase activity.

Tanapox virus (TANV) A species in the genus Yatapoxvirus causing local skin lesions in children in Kenya. The illness is non-fatal and of short duration. Appears serologically the same as a virus causing disease in captive monkeys. Anti-genically related to Yaba monkey tumor virus. Does not grow in eggs but replicates in monkey kidney cell cultures. Causes single and multiple lesions in monkeys. Monkey handlers have also been infected.

Synonyms: benign epidermal monkeypox virus; Yaba-like disease virus.
