Most adenoviruses use the coxsackie-adenovirus receptor (CAR) as a major cellular receptor. We have shown recently that adenovirus types 8, 19a, and 37, which are the major causes of epidemic keratoconjunctivitis, use sialic acid rather than CAR as a major cellular receptor. The predicted isoelectric point of the receptor-interacting knob domain in the adenovirus fiber protein is unusually high (9...
Poliovirus type 1 was isolated from an immunodeficient patient 4 days after onset of paresis (IS1) and after 5.5 years of prolonged enteral virus replication (IS2). Antigenic characterization revealed that IS1 was Sabin 1-like, whereas IS2 reacted like poliovirus 1 Mahoney. Complete genomic sequencing demonstrated the phylogenetic relationship (94.9% identity) of IS1 and IS2, which differed from the...
As enterovirus infections of the heart cause myocarditis and eventually congestive heart failure, the antiviral activity of ribavirin was studied in coxsackie virus B3 (CVB3)-infected carrier cultures of human myocardial fibroblasts. Cultures were infected 7 days before application of ribavirin and effects were evaluated over a period of 16 days by plaque assays and in situ hybridization. Compared...
The fiber and hexon genes of the immunological adenovirus (Ad) variant strains Ad9/Hx and Ad15/Hx, belonging to subgenus D, were sequenced and compared to the corresponding sequences of the prototypes Ad9 and Ad15. It was found that the variants possessed a novel and identical hemagglutinin as they could not be distinguished by hemagglutination-inhibition tests. These serological data were now confirmed...
The hexon genes of human adenovirus (AV) types 3, 16 (both subgenus B), and 4 (subgenus E) were sequenced and the nucleotide and predicted amino acid sequences were compared. We observed a high degree of homology between the three serotypes and thus could confirm the close evolutionary relationship of subgenera B and E which was previously inferred after comparing other genome regions. Employing the...
The fiber genes of human adenovirus types 8, 9, 15, and two genome types of intermediate adenovirus 15/H9, allbelonging to subgenus D, were sequenced and the nucleotide and predicted amino acid sequences compared. The analyzed peptide sequences were consistent with the structural domains described for other adenoviruses: an amino-terminal tail region, an intervening shaft region composed of eight...
