Parana, a new tacaribe complex virus from Paraguay
Archiv f�r die gesamte Virusforschung, 1970Parana virus, an agent isolated fromOryzomys buccinatus rodents trapped in the Misiones Department of Paraguay, was found to be related to the Tacaribe complex of viruses by complement-fixation tests, but was distinct by neutralization and direct immunofluorescent tests. It shares the basic properties of chloroform sensitivity, a ribonucleic acid core,

Defective interfering Tacaribe virus and persistently infected cells
Virology, 1980Abstract Persistently infected (PI) BHK 21 and Vero cell lines were established by infection with wild-type (wt) Tacaribe virus and passage of surviving cells. These cells release defective interfering (DI) Tacaribe virus particles, which caused complete inhibition of plaque formation by wt Tacaribe virions.

Tacaribe virus infection of guinea-pig
Archiv f�r die gesamte Virusforschung, 1967Guinea-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, 1994Tacaribe 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 ...

Tacaribe virus: A new alternative for Argentine hemorrhagic fever vaccine
Journal of Medical Virology, 1987AbstractTacaribe 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, 1980Guinea 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.

Serological Evidence of Infection of Tacaribe Virus and Arboviruses in Trinidadian Bats
The American Journal of Tropical Medicine and Hygiene, 1978Sera 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.

Characterization of Oliveros Virus, a New Member of the Tacaribe Complex (Arenaviridae: Arenavirus)
The American Journal of Tropical Medicine and Hygiene, 1996Oliveros virus is an agent isolated in cell culture from Bolomys obscurus (Rodentia, Muridae, Sigmodontinae) captured on the central Argentine pampa. Oliveros virus was shown to be related to members of the Tacaribe complex of the family Arenaviridae by immunofluorescent antibody (IFA) tests, electrophoretic pattern of viral proteins, and morphology as

Virulence alterations of Tacaribe virus infection in adult mice: Lethal model for encephalitis
Archives of Virology, 1978Selection of population of Tacaribe virus strain 11573 lethal for mice was carried out by serial intracerebral passage of the virus in adult mice. Viral populations have been characterized by determination of virulence for suckling, weanling, and adult mice, and by histopathologic changes observed in brains of adult mice after intracerebral inoculation.

MyD88 expressing T cells are required for neuropathogenesis of Tacaribe virus. (39.6)
The Journal of Immunology, 2010Abstract Immune responses play a key role in the pathogenesis of viral encephalitis. Infection of neonatal C57Bl/6 (B6) mice with neurotropic arenavirus Tacaribe (TCRV) results in encephalitis, paralysis and death within 15 days of challenge. Analysis of the expression of 96 immune related genes using a mouse Taqman Low Density Array (
