Observations on Some Little-Known Adenoviruses

Summary

The occurrence of a number of little-known adenovirus serotypes in children in an institution in Washington, D. C., is described. These viruses, which included types 9, 10, 12, 13, 16, 17, 24, 25, 26, 27, 28, BP-6, and BP-7 were isolated almost exclusively from anal specimens. As a group they were almost as common as the better known serotypes 1, 2, 3, and 5. It was shown that the latter types, although frequently present in routine throat specimens, were also more frequently isolated from routine anal specimens. Homotypic hemagglutination-inhibition antibody rises were demonstrated in children infected with most of the little-known serotypes.
