Fig. (1) Effect of endophytic fungal extracts on HIV-1 replication. This graph is representative of results seen in all 100 extracts tested. A3.01 cells were infected with HIV-1_LAV in the presence of the extracts CS, CT, B, G and I at a concentration of 2 µg/mL. Controls for DMSO concentration present in extract wells (DMSO), positive inhibition of viral replication (1 µM and 2 µM AZT), and absence of extract (LAV) and virus (mock) were included. Virus levels in culture supernatant were determined by RT assay.
