[Virological and serological characteristics of outbreaks and sporadic cases of acute gastroenteritis].

Specimens from patients with gastroenteritis (GE) collected during outbreaks and from sporadic cases reported in the USSR in 1979-1984 were examined by electron microscopy (EM), enzyme immunoassay, rotavirus neutralization test in cell culture. All the winter-spring outbreaks and a considerable number (34.9%) of sporadic GE cases were caused by rotaviruses.

[A method of solid-phase analysis of antigens using Staphylococcus aureus as the label].

A new method of solid-phase analysis of viral antigens in which St. aureus, strain Cowan 1, was used as a label is described. The result of analysis is read visually by bacterial agglutination.
