The causative agent of scarlatina. Prof. S. I. Zlatogorov, V. I. Kudryavtseva, and B. L. Palant (Journal of Microbes, vol. V, issue 2)

In experiments with inoculations of treated cultures of scarlet streptococcus and infection of monkeys the authors obtained confirmation of their assumption about close symbiosis of this microbe with the scarlet virus. In this symbiosis and in the activation of streptococcus by this virus lies the cause of its pathogenic effect on the organism.
