HBV DNA can be detected from nail clippings of HBs Ag positive patients.

proteinase K and was then incubated for 4 hrs at 55•Ž . After approximately 30 mg of nail clippings in a 1.5 ml microtest tube were rinsed once with 1.0 N NaOH and twice with distilled water, the nails were mixed with 300ƒÊ1 of 4 M guanidine thiocyanate, 0.5% (w/v) sodium N-lauroyl salcosinate, 25 mM sodium citrate, and 0.1 mM 2-mercaptoethanol [7], and were incubated at room temperature over n...

tattooling and hbs ag

to investigate the association between tattooing and hepatitis b surface antigen (hbsag), sera form 49 tattooed individuals, mostly men aged 15-62 years, and 82 healthy controls matched for age, sex and social class were tested for hbsag and anti-hbsag. hbsag was detected more significantly in tattooed cases than in controls, 24.5% and 6% respectively. seven (33%) of the individuals who had bee...

[Evaluation of HBs Ag, HCV and HIV Ag-Ab Assays using Bio-Rad Elite Microplate Analyzer.].

BACKGROUND In this study, we evaluated the performance of Elite microplate analyzer (Bio-Rad Laboratories, France) and the related assays (ULTRA line) for the detection of hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). METHODS Seroconversion panels, HBsAg positive/HBsAg negative (n=99/n=1,422), anti-HCV positive/negative (n=97/n=1,670), and anti-HIV p...

(HBs-Ag) and anti-HCV Antibody Among Health Care Workers of Canton Sarajevo (Bosnia and Herzegovina)

Mutational analysis of HBs Ag-positive mothers and their infected children despite immunoprophylaxis.

Hepatitis B vaccination is safe and effective, although breakthrough infection occasionally occurs in those who receive the vaccine and hepatitis B immunoglobulin (HBIg) prophylaxis. Sequence variation in their antigenic regions is one of the most powerful strategies that are used by viruses to escape recognition by B and T cell-mediated immune responses. The aim of this study was to explore th...
