[A comparison of the efficacy of the passive hemagglutination reaction and the reverse passive hemagglutination reaction for detecting the rotavirus antigen in feces]. / Sravnenie éffektivnosti ispol'zovaniia reaktsii passiv gemaggliutinatsii i reaktsii obratnoi passivnoi gemaggliutinatsii dlia indikatsii rotavirusnogo antigena v fekaliiakh.

These two tests have been used for the detection of a rotaviral antigen in feces of patients suffering from gastrointestinal disorders. Antibody erythrocytic rotaviral diagnostic agent has been employed in both the tests. A comparative analysis has demonstrated the specificity of both the tests for the indication of a rotavirus and a higher sensitivity of passive hemagglutination.

[Detection of oncornavirus type D in continuous breast cancer cells]. / Ubnaruzhenie onkornavirusa tipa D v perevivaemykh kletkakh raka grudnoi zhelezy.

An oncornavirus immunologically similar to oncornaviruses type D previously isolated from human continuous cells was detected in continuous cells of mammary cancer (SH3). The culture produces structures having densities of 1.18--1.19 and 1.22 g/ml which contain high molecular RNA (68S) and reverse-transcriptase activity. The similarity of this virus with other oncornaviruses was also demonstrated in molecular hybridization experiments.

[Transfection by integrated proviruses]. / Transfektsiia integrirovannymi provirusami.

Three lines of continuous mouse L cells were compared: one of them contained only its endogenic oncornavirus, another was contaminated with SV5 virus, and a third was obtained from the second line chronically infected with vesicular stomatitis virus. Experiments with transfection showed that it was possible to recover SV5 virus from the two former cultures and vesicular stomatitis virus from the latter.
