Infantile gastroenteritis can be caused by several of the established adenovirus types. There are also adenoviruses that defy in vitro cultivation but have been recognized by electron microscopy. One isolate of these viruses, which have been designated enteric adenoviruses, has been characterized. Several of the established adenovirus types are shed in stools over long periods. The conditions for direct identification of enteric adenoviruses by immunoelectroosmophoresis (IEOP) have therefore been evaluated. Application of this technique requires highly specific reagents. However, a high prevalence of antibodies in rabbits reacting with human rotavirus was noted. For these reasons, immunoadsorbent purified antibodies were prepared. Because of the difficulty in purifying immunogens from stools, an immunization procedure characterized by immunization with adenovirus subunits bound to affinity chromatography beads was elaborated. An identification procedure for adenoviruses causing infantile gastroenteritis based a) on IEOP using group-specific and monospecific antibodies and b) on the determination of the in vitro cultivatability is suggested.

Infantile gastroenteritis virus (orbi-group) recovered from stools of infants with acute nonbacterial gastroenteritis was administered per os to germfree and conventional piglets. Virus was found subsequently in stools and in the mucosal epithelial cells of the small intestine of these animals. Some animals developed diarrhea. Added proof of orbivirus replication was obtained through the use of tritiated uridine injections and the recovery of labeled virus in gut contents at the time of autopsy. Serological conversion was demonstrated in infected germfree piglets.
