Characterization of an intermediate adenovirus strain.

An intermediate strain of human adenovirus of subgenus D was investigated by type specific serological reactions and restriction endonuclease analysis. The latter method showed the strain identical to the prototype strain of human adenovirus type 9 as well as did serum neutralization tests. In contrast with the previous methods haemagglutination inhibition tests showed the strain related to both the prototypes strains of human adenovirus 9 and 13.
