| Abstract: | HBs antigens were subtyped in blood samples of intravenous drug-addicts (IDA) and of donors from as many as 10 cities of Western Siberia by using the immune-enzyme assay with 6 high-specific monoclonal antibodies. Two HBsAg subtypes were found, in a ratio of 3% ayw2: 97% ayw3 (varA and varB), in IDA blood samples from Novosobirsk. Three HBsAg subtypes were found, in a ratio of 57% ayw2: 42% ayw3 (varA and varB): 1% adw2, in the donors' blood samples. The obtained data are sufficient for developing the first national sera panel containing different HBsAg subtypes of hepatitis B virus typical of Russia. |
