however , these antiretrovirals even in high concentration only minimally inhibited chronic , established hiv infection : while zidovudine ( 0.01 micrograms/ml ) inhibited infection by over 90 % in acutely infected macrophages and lymphoid cells , 50 micrograms/ml of this antiretroviral produced only 19-55 % inhibition of hiv replication in chronically infected cells .
