Hepatitis B virus and hepatitis delta virus subtypes circulating in Algeria and seroprevalence of HDV infection.

Background: Little is known about molecular characteristics of HBV strains circulating in Algeria and there are few data regarding HDV infection.

Objectives: The aim of this study is to describe the genetic diversity of HBV and HDV strains existing in Algeria and to determine the seroprevalence of HDV infection.

Study Design: Plasma samples from 134 patients were analyzed by enzyme immunoassay method for HBV and HDV serological markers.
