Apatient with chronic hepatitis B was infectedwith HBV-DNA YMDD variant strains natu-rally before treatment with lamivudine. The pa-tient, female, 52 years old, has never receivedantiviral therapy. Before hysteromyomectomy,she received physical and biochemical examina-tion. Her levels of alanine aminotransferase werehigher than 140 μ/L and HBsAg was positive.She was subjected to further examination. Anti-HBe/HBV DNA was positive in the serum andYMDD variant was detected in the region of thereverse transcriptase of HBV, with methionine(M) at HBV codon 552 replaced by isoleusine(I) by direct sequence analysis of PCR products.The patient took 100mg of lamivudine orally once
