background: more than 350 million people are chronic carriers of hepatitis b virus (hbv) and because of the high hbv-related morbidity and mortality, the global disease burden of hbv is substantial. in patients with hbeag–negative chronic hepatitis b (chb) with serum alanine aminotransferase (alt) levels, 1-2 × upper limit of normal (uln) and hbv dna load of 10000 to 100000 copies/ml, liver bio...

This study assessed the seroepidemiology of Toxoplasma gondii, Hepatitis B Virus and their co-infection infection in women of child-bearing age in communities in Osun State, Nigeria.

conclusions we introduced an anti-hbsp antibodies elisa, designed for locally circulating hbv strains. correlation observed of anti-hbsp with liver fibrosis staging regardless of viral replication and liver inflammation suggests anti-hbsp antibodies as possible indicator for hbv-associated liver fibrosis. results seven out of eighty (9%) chb patients were positive for anti-hbsp antibodies. mean...
