Abstract: In the absence of drugs, the ratio of virus carrying the
M184I mutation decreased to 5.3%, while wild type virus increased to 94.7%; the ratio of virus carrying
Y181I increased to 75%, while wild type virus decreased to 25% after 4 passages.
Abstract: RESULTS: 3TC-resistant (
M184I mutation) and NVP-resistant (
Y181I mutation) virus should be selected in vitro in two different ways.
Abstract: The competitive replication assay showed that the ratio of virus carrying a
M184I mutation increased from 98.8%, while the wild type virus decreased to 1.2% after 4 passages in the presence of 3TC; the percentage of virus carrying the
Y181I mutation increased to 90.5%, while wild type virus decreased to 9.5% in the presence of NVP.
