Abstract: In particular,
E34Q,
K43T, and
K55R, which were associated with lopinavir treatment, correlated with mutations associated with lopinavir resistance (
E34Q with either
L33F or
F53L, or
K43T with
I54A) or clustered with multi-
PI resistance mutations (
K43T with
V82A and
I54V or
V82A,
V32I, and
I47V, or
K55R with
V82A,
I54V, and
M46I).
