Vertical transmission of hepatitis B virus from father to child: what can be concluded about this possibility?
AbstractVertical hepatitis B virus (HBV) transmission is defined as transmission that occurs during pregnancy or postpartum from an HBV-infected mother to her fetus or child. It is an efficient route for the spread of HBV and is responsible for most of the cases of chronic HBV infection in adults. During pregnancy, vertical transmission can occur in the intrauterine phase, by placental infection via peripheral blood mononuclear cells, by placental leakage, or through female germ cells.The detection of HBV DNA in semen and spermatids from HBV-infected men has provided strong evidence that the male genital tract may act as a...

Complete genome sequence of a new virus from Allium sativum L in China
AbstractThe complete genome of a new virus belonging to the familyBetaflexiviridae was identified in garlic and sequenced by next-generation sequencing and reverse transcription PCR. The complete RNA genome (GenBank accession number OP021693) is 8191 nucleotides in length, excluding the 3 ’ poly(A) tail, and contains five open reading frames (ORFs). These open reading frames encode the viral replicase, triple gene block, and coat protein, and the genome organization is typical of members of the subfamilyQuinvirinae. The virus has been tentatively named"garlic yellow curl virus" (GYCV). Phylogenetic analysis sug...
