| junin virus access to cns by extraneural rat inoculation. | this study was carried out to determine the pathways along which two strains of junin virus (jv), the pathogenic xjv and the attenuated xjc13v, reach the cns following ip inoculation of 2-day-old rats. a sequential study of infectivity and antigen distribution in peritoneal macrophages, spleen, and brain was performed. mortality was 85% with the former strain, but only 15% with the latter. at 4-7 days pi, xjv-infected animals had viral antigen in 10% of peritoneal macrophages. viremia and spleen ... | 1986 | 3009706 |
| effect of ribavirin and tributylribavirin on argentine hemorrhagic fever (junin virus) in guinea pigs. | subcutaneous injections of ribavirin into guinea pigs infected intraperitoneally or intracerebrally with junin virus significantly increased the mean time to death but did not enhance survival of the animals. we found similar results with tributylribavirin. virus replication was delayed, but not prevented, in ribavirin-treated infected guinea pigs. the animals usually died with high virus titers in their brains and frequently were paralyzed. | 1986 | 3013087 |

| macrophage maturity and modulation of response to junín virus in infected rats. | replication of junín virus in peritoneal macrophages from newborn rats was greater for prototype strain xj than for strain xjc13, whereas in cells from adult animals viral multiplication proved minimal. transfer of peritoneal adherent cells from normal adult to strain xj-infected newborn rats lowered mortality significantly. silica blockade of macrophages protected two-day-old strain xj-infected animals and depressed brain titers of virus significantly, whereas treatment had no effect on strain ... | 1986 | 3016114 |
| partial characterization of two temperature-sensitive mutants of junin virus. | two temperature sensitive (ts) mutants of junin virus, a member of arenaviridae, have been partially characterized. both mutants, named ts-32 and ts-40, had a relative plating efficiency 40 degrees c/34 degrees c lower than 10(-3) an exhibited a leak yield below 10(-4). standard growth curves showed that at 34 degrees c the viral mutants multiplied slower than wt virus and at high multiplicity did not display autointerference. no differences in thermolability were observed between wt and ts muta ... | 1986 | 3018452 |
| chronic neurologic disease in junín virus-infected rats. | the purpose of this study was to determine whether junín virus persistence in cns of rats was capable of inducing late neurologic disease. following intracerebral inoculation of newborn animals with xj strain, three distinct stages could be discerned: an early phase of acute disease, up to 30 days pi, with 5% mortality; an intermediate one, extending to 280 days pi, without clinical signs but with evident viral persistence; and a final period of chronic illness, featuring clinical neurologic syn ... | 1986 | 3020168 |
