Use of 15,000 or 5,000 therapeutic units of immune sera prevented all signs of illness when administered within 24 hr of infection. We could also prevent illness and death in infected guinea pigs as late as 6 days after infection if we used more antisera (30,000 therapeutic units\/ kg). In some treatment groups, surviving animals developed a late neurological syndrome with prominant rear\u2010limb paralysis. Treated animals typically expressed higher viral titers in the brain than in any other organ. There appeared to be no acute exacerbation of disease by antibody administration. Our data suggest that, after replicating peripherally, Junin virus infects the brain where circulating immunoglobulins may not eliminate viable virus. Subsequent replication of virus in the brain may generate a neurological phase of the illness. Histological examination of brains from guinea pigs in treatment groups favoring the neurological phase of illness showed encephalitis, meningitis, and swollen astrocytes, suggestive of neuronal degeneration. There is likely a delicate balance among presence of virus in the brain, the amount of antibody transported into the central nervous system, and the occurrence of this late neurological aspect of experimental Argentine hemorrhagic fever. Further study of this model may elucidate factors relevant in understanding the continuing problem of the late neurological syndrome seen in some human cases of Argentine hemorrhagic fever treated with immune plasma.<\/jats:p>","DOI":"10.1002\/jmv.1890200303","type":"journal-article","created":{"date-parts":[[2007,3,2]],"date-time":"2007-03-02T12:51:30Z","timestamp":1172839890000},"page":"207-218","source":"Crossref","is-referenced-by-count":40,"title":["Treatment of Junin Virus\u2010Infected Guinea Pigs With Immune Serum: Development of Late Neurological Disease"],"prefix":"10.1002","volume":"20","author":[{"given":"Richard H.","family":"Kenyon","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David E.","family":"Green","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerald A.","family":"Eddy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Clarence J.","family":"Peters","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,12,11]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"136","volume-title":"Biology of the Immune Response","author":"Abramoff P","year":"1970"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/143.1.7"},{"key":"e_1_2_1_4_1","unstructured":"Centers for Disease Control(1976): \u201cClassification of Etiologic Agents on the Basis of Hazard.\u201d 4th ed.
