Abstract excerpt

BACKGROUND: Hepatitis B virus infection is frequent among Amerindians. In Argentina HBV genotypes A, B, C, D, E, F and H were described in different populations, while some cases of occult hepatitis B infection (OBI) were reported in human immunodeficiency virus (HIV) coinfected patients. OBJECTIVE: To determine the prevalence, genetic diversity of HBV and to analyze the deduced amino acid sequence of both S and...
