Tamiami Virus, a New Member of the Tacaribe Group

The American Journal of Tropical Medicine and Hygiene, 1970
Abstract Nine strains of a new virus have been isolated from wild cotton rats collected in south Florida. The virus, for which the name Tamiami is suggested, was characterized by its sensitivity to sodium deoxycholate, its thermolability, the extended survival time of fatally infected mice, and isolation from Cricetine rodents. Antigenically, the virus

Tacaribe virus infection of guinea-pig

Archiv f�r die gesamte Virusforschung, 1967
Guinea-pigs were inoculated with live Tacaribe virus by the intramuscular route. For a period of 48 days after inoculation infectious virus was isolated from lymph nodes, but not consistently. Virus is present in serum on the 7th day and in liver on the 13th day.

Tacaribe Virus Gene Expression in Cytopathic and Non-cytopathic Infections

Virology, 1994
Tacaribe virus (TV) replication was compared in Vero cells infected under conditions leading either to cell death (c.p.e.(+) infection) or to the establishment of persistence (c.p.e.(-) infection). To this end, two virus preparations were employed: one containing a ratio of standard (plaque-forming) viruses to interfering particles (IP) that would ...

Subgenomic RNAs of Tacaribe Virus

1993
Tacaribe virus (TV) is the prototype of the Tacaribe group of serologically defined viruses geographically distributed in the Americas. Two of these viruses are human pathogens responsible for hemorrhagic fever, i.e., Junin virus in Argentina and Machupo virus in Bolivia.

Nontemplated bases at the 5′ ends of tacaribe virus mRNAs

Virology, 1990
Centrifugation of Tacaribe arenavirus-infected cell extracts on CsCl density gradients was used to separate genomes and antigenomes, which band at 1.31 g/ml as nucleocapsids, from mRNAs which pellet. Primer extensions on the banded RNAs showed that the 5' ends of the genomes and antigenomes were unique, whereas primer extensions on the mRNAs showed ...

Tacaribe virus: A new alternative for Argentine hemorrhagic fever vaccine

Journal of Medical Virology, 1987
AbstractTacaribe virus is know to protect guinea pigs and primates against lethal challenge with Junín virus. A long‐term study on the effect of Tacaribe virus infection in the guinea pig was carried out to determine the extent of cross‐protection and whether antigen and/or viral persistence and tissue damage could be detected in immune animals.

Protection of Guinea Pigs Inoculated with Tacaribe Virus against Lethal Doses of Junin Virus

Journal of Infectious Diseases, 1980
Guinea pigs were protected against lethal doses of Junin virus by a previous inoculation with Tacaribe virus. Fourteen guinea pigs were infected with 10(6) 50% lethal doses (LD50) of Tacaribe virus and superinfected 45 days later with 10(3) LD50 of Junin virus. Appropriate control groups for both infections were also studied.

Tacaribe virus L gene encodes a protein of 2210 amino acid residues

Virology, 1989
The nucleotide sequence of Tacaribe virus (TV) L gene was obtained from two sets of overlapping cDNA clones constructed by walking along the virus L RNA using two successive synthetic DNA primers. Analysis of the sequence indicated the existence of a unique long open reading frame in the viral complementary strand.

An antiviral factor fromMelia azedarach L. prevents Tacaribe virus encephalitis in mice

Experientia, 1986
Treatment of neonatal mice with an antiviral factor, (AVF), obtained from the leaves of Melia azedarach L. protected them against lethal encephalitis caused by Tacaribe virus inoculation. The degree of protection obtained varied from 66% to 100% depending on the virus dose.

Serological Evidence of Infection of Tacaribe Virus and Arboviruses in Trinidadian Bats

The American Journal of Tropical Medicine and Hygiene, 1978
Sera from 39 species of bats collected in Trinidad between 1972 and 1974 were tested against some or all of 18 arboviruses in hemagglutination inhibition (HI) and/or suckling mouse neutralization (N) tests. A few sera were HI-positive with Mucambo, eastern equine encephalitis (EEE), Oriboca, Restan, Manzanilla, Guama, Bimiti, and Catu.
