  1. MT2 cells were infected by pseudotyped G367R viruses at 4-fold dilutions and grown in the presence of entry inhibitors. The cultures were then split into 2 wells at day 7 with only one of them being maintained in the presence of inhibitors.
  2. aContinuous represents the maintainance of the entry inhibitors in the cultures. Withdrawal represents drug withdrawal after 7 days of infection.
  3. bCPE = cytopathic effect.
  4. cNumbers of samples in which CPE was observed over 5 weeks after infection.
  5. devaluated during 28 days following infection. p24 values of CPE negative samples were lower than listed.
