As you will read from this paper:
1. hbvdna is detected in the sperm (germ cell)
2. hbvdna is detected in the cord blood of baby born to mother who is HbsAg-ve, but father is HBsAg+ve.
3. We all accept that HBV viral dna can be integrated into the liver cell's dna.
My questions are:
1. Can the integrated hbv/human dna produce a complete virion (Dane particle)?
2. If hbvdna is detected in the sperm, how is it produced (got there)?
3. Where did the hbvdna in the cord blood come from?
If we assume hbv viral dna is integrated into the human genes (via the sperm), this should mean hbv viral dna must be present in the dna of every cell in the body. Has this ever been found to be the case?
It is very frustrating that the paper did not mention whether the two neonates are later found to be HbsAg+ve.
P.S. My Chinese is not that good, so I may have misunderstood the paper. Please correct me if I am wrong.
