Protection conferred against Junin virus infection in rats. 1984

J L Blejer, and N V Galassi, and V M Saavedra, and M R Nejamkis

2-day-old Wistar rats intracerebrally infected with the XJC13 strain of virus exhibited a 5% survival rate which rose to 71% after immune serum treatment. Brain viral titers were relatively unaffected by this treatment. Histologic studies showed necrosis in the cerebellum and brain cortex with mononuclear cell infiltration in both treated and nontreated groups. Beginning on day 16 postinfection, however, intracerebral perivascular gliosis foci and mild meningeal congestion were minimal in the treated animals. These findings imply that passively transferred humoral immunity leads to prompt recovery in this experimental model.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001116 Arenaviridae A family of RNA viruses naturally infecting rodents and consisting of one genus (ARENAVIRUS) with two groups: Old World Arenaviruses (ARENAVIRUSES, OLD WORLD) and New World Arenaviruses (ARENAVIRUSES, NEW WORLD). Infection in rodents is persistent and silent. Vertical transmission is through milk-, saliva-, or urine-borne routes. Horizontal transmission to humans, monkeys, and other animals is important.
