[Rotavirus diarrhea in young infants].

Clinical and serological studies were made in 62 children with various purulent infections, who were placed in the same hospital unit. The precipitation test with the antigen of monkey virus SA-11 showed that diarrhea in 32 of these children was etiologically linked with rotaviruses. The diagnostic titers of virus antibodies were detected in children having diarrhea 5.

[Virological and serological study of rotavirus gastroenteritis].

Cases of acute gastroenteritis with negative bacteriological analyses were examined. Preparations of feces collected from patients in the acute stage of the disease were found by immune electron microscopy to contain typical rotavirus particles forming specific aggregates in the presence of convalescent sera. Examinations of paired acute and convalescent sera of the patients revealed the presence in convalescent sera of specific antibodies neutralizing simian rotavirus SA 11 antigenically related to human rotavirus.
