[Cultivation of HIV-1 virus on mononuclear peripheral blood cells of HIV-1 seropositive individuals]

Abstract

Using the method of co-cultivation with phytohaemagglutinin-stimulated lymphocytes from healthy donors, the author isolated the HIV-1 virus from peripheral mononuclear blood cells of three patients with the AIDS symptomatology and one patient with the ARC symptomatology. The presence of the virus in infected cells was proved by detection of the viral antigen p 24 in enzymatic immunoassays and in the immunofluorescence test. Three of the isolated strains were adapted to sensitive continual tissue cultures, where the isolates caused chronic infection of the cells associated with the development of a cytopathic effect. In the investigated patients no relationship was proved between viraemia and antigenaemia. The author discusses the importance of virus cultivation for laboratory diagnosis, epidemiology and research of HIV infection and AIDS.
