Cross-reactivity between Enteric Adenoviruses and Adenovirus Type 4: Analysis of Epitopes by Solid-phase Immune Electron Microscopy

Abstract

The immunological relationships between the two newly discovered serotypes of enteric adenoviruses, Ad40 and Ad41, and antisera to human adenoviruses representing all subgroups were studied by solid-phase immune electron microscopy. A pronounced two-way cross-reaction was seen between Ad40 (subgroup F) and Ad41 (subgroup G). Furthermore, a distinct one-way cross-reaction was noted between adenovirus type 4 antiserum (subgroup E) and virions of Ad40.
