Abstract: CONCLUSIONS: PC-P159T (ntC2288A), BCP-N118T (ntA1726C), BCP-L134L (ntA1775C/G/T), PC-G182C (ntG2357T) and PC-S64A/T (ntT2003G/A) were novel identified mutations that impacted IFN therapeutic efficacy.
Abstract: In the RT gene, Q149K was the most frequently identified amino acid substitution (9.83%), followed by L122F (8.19%), N118D/T (6.55%), L157M (4.91%), and H124Y (3.27%).
Result: The Q149K was the most frequently identified amino acid substitution observed in these isolates (9.83%), followed by L122F (8.19%), N118D/T (6.55%), L157M (4.91%), and H124Y (3.27%).
Discussion: The most prevalent mutations in RT region of the study isolates was Q149K (9.83%) followed by N118D/T

Characterization of the occult hepatitis B virus variants circulating among the blood donors from eastern India.
Abstract: Subsequent to the instigation of antiviral therapy, the dominant drug resistant HBV which caused virological breakthrough and was associated with hepatic failure displayed a series of unique mutations particularly in the BCP (A1762T and G1764A) and in the polymerase (rtL180M, rtM204V, rtA222T and rtL336V), core (cP5T, cS26A,
