A study was conducted in an area of hepatitis B hyperendemicity to determin whether contact with infective bodily secretions or contaminated environmental surfaces could be involved in the transmission of the hepatitis B virus. Hepatitis B surface antigen was detected in gingival swab, saliva, and impetiginous lesion exudate samples from children. Hepatitis B surface antigen also was found in s...

Hepatitis B virus (HBV) is an etiological agent of hepatitis B infection. Hepatitis B is a life-threatening disease that affects the liver. The clinical outcomes of the disease are varied from asymptomatic disease to serious complication such as cirrhosis and hepatocellular carcinoma (HCC). Despite availability of the vaccine and appropriate treatment, hepatitis B infection still remains a majo...

The purpose of the present study was to measure the amount of antibody to hepatitis B core antigen (anti-HBc) in different populations by the immunoelectroosmophoresis method. High titers of anti-HBc, up to 1/4,096, were found in the acute stage of hepatitis B virus infections and in the chronic carrier state of hepatitis B surface antigen. In cases of acute hepatitis the anti-HBc titers gradua...

results hepatitis b surface antigen (hbsag) was found in 122/3000 (4.1%) prisoners. hepatitis b e antigen (hbeag), anti-hiv, anti-hcv and anti-hiv/anti-hcv were detected in 52/122 (42.6%), 12/122 (10%), 22/122 (18%) and 3/122 (2.4%) prisoners, respectively. the hbv-dna was found in 115/122 (94.3%) prisoners. the most high risk behavior was to utilize the collaborative syringe by injecting drug ...

objective(s) the aim of this study was to characterize the hepatitis b virus surface protein genotypes and sequence variations among hepatitis b virus surface antigen (hbsag) positive chronic patients in hormozgan province, south of iran. materials and methods a total of 8 patients enrolled in this study. the surface gene was amplified and directly sequenced. genotypes and nucleotide/amino acid...

We conducted Myanmar-Japan cooperation studies on hepatitis B and hepatitis C virus markers in patients with thalassemias and those with liver diseases. Among the 102 patients with liver diseases, 92% had a history of hepatitis B virus infection (antibody to hepatitis B core antigen positive), 35% were hepatitis B surface antigen positive, 39% were positive for anti-HCV. Among 28 patients with ...

 Abstract Background: Investigators were suspicious of tyrosine-methionine-aspartate-aspartate (YMDD) mutations occurred only in patients who were treated by lamivudine. However, YMDD mutations of hepatitis B virus gene (HBV DNA) in patients with chronic hepatitis B (CHB) untreated with antiviral medicines was reported in some studies. The aim of this study was to evaluate YMDD mutations in Ira...
