Junin virus isolation from lympho-mononuclear cells of patients with Argentine hemorrhagic fever.Intervirology. 1986; 25(2):97-102.I
Detection of viremia was attempted by three different methods in 30 cases of Argentine hemorrhagic fever (AHF). Cocultivation of peripheral blood mononuclear cells (PBMC) with Vero cell monolayers was the most sensitive, detecting Junin virus (JV) in 96% of the cases. Inoculation of whole blood into suckling mice and on Vero cells rendered 53 and 46% of positive isolations, respectively. The results presented suggest that PBMC are infected with JV during the acute period of AHF. JV was isolated with decreasing frequency up to 3 days after treatment with immune plasma, but no virus was recovered from PBMC during early convalescence.
