title: High genetic stability of the region coding for the structural proteins of yellow fever virus strain 17D.
abstract: The genome of the Pasteur 17D-204 vaccine strain of yellow fever virus has been cloned into pBR327. The inserts of recombinant plasmids were analysed by restriction cleavage pattern and compared with that of the genome of another substrain previously cloned and sequenced. Ten of the overlapping inserts were found to contain the sequence of the complete genome. We have sequenced approximately 3680 bases of the 5' region which codes for the C, M and E structural proteins and the NS1 non-structural protein. This sequence is the same as that reported previously, indicating a remarkable stability of these two vaccine substrains.
