Abstract: Several immune-epitope mutants, such as
S45T/A,
N131T,
I194V, and
S207N in
S, were detected in all isolates.
Conclusion: Several immune-epitope mutants, such as
S45T/A,
N131T,
I194V, and
S207N in
S, were detected in all isolates and needed to explore their role in
HBV infection.
Result: Four replacements (
S45T/A,
N131T,
I194V, and
S207N) within the immune epitopes were observed in all isolates.
