Method: Among these, 5 isolates showed
RT V106 (
V106I,
V106V/I,
V106A, and
V106M/T) substitutions in combination with one or more of
A98A/G,
H221H/Y,
P225P/H, F227 (as
F227C or
F227C/R), or
Y318Y/F RT substitutions, and 1 had genotypic resistance conferred through a
Y188L substitution alone.
Method: One isolate displayed the
Y318Y/F DOR resistance-associated
RT substitution but did not show phenotypic resistance.|mg
