Underestimation of HIV type 1 drug resistance mutations: results from the ENVA-2 genotyping proficiency program.

abstract：:Vaginal SHIVSF162P3 acquisition in pigtail macaques (Macaca nemestrina) is dependent on time point during the menstrual cycle. Susceptibility is higher around menstruation and lower at ovulation in mid cycle. This complicates the design of repeat low-dose (RLD) SHIV exposure studies because virus challenges given duri...
