A test system of enzyme immunoassay (EIA) consisting of simian rotavirus SA-11 and rabbit antiserum has been developed for the detection of rotavirus antigen. Direct EIA was used for tests on stool specimens from 289 children varying in ages from 10 days to 12 years suffering from acute enteric infections and 56 normal children. The antigen was detected in 22.

The effect of proteases inhibitors, epsilon-amino-caproic acid and gordox, on reproduction of rotavirus SA-11 in MA-104 cells was studied by enzyme immunoassay. These inhibitors were shown to exert an inhibiting effect on rotavirus reproduction.

Scanning microscopy was used to examine the features of morphology and attachment to a solid substrate of a transformed and tumor lines of hamster cells. These cell lines differed from normal hamster fibroblasts by changes in the mode of attachment and the degree of flattening on the solid substrate, relief of the cell surface and pattern of intercellular interactions. The observed morphological changes correlated with the degree of cell transformation.

Combined virological, antigenic, electron microscopic, and molecular biologic study of the role of an oncovirus, herpes simplex type 2 virus (HSV-2), in the mechanisms of transformation of HSV-2-infected hamster cells was carried out. No expression of genetic information of the oncovirus could be detected. Cell transformation was shown to be associated with persistence and realization of HSV-2 genetic information in the transformed cells.
