Zdrodovsky-Sanarelli Phenomenon

The Zdrodovsky-Sanarelli phenomenon (ZP) is a phenomenon that was discovered and described in the 1930s by the Soviet microbiologist P. F. Zdrodovsky and the Italian hygienist G. Sanarelli. The phenomenon is that, under certain conditions, microorganisms can multiply twice as fast as normal.

ZF was discovered while studying the process of bacterial reproduction under various conditions. It has been found that bacteria can grow and multiply faster if they are in a certain environment, such as an environment containing certain nutrients or substances that stimulate the growth of microorganisms.

However, MF is not a universal phenomenon, and not all microorganisms exhibit it. In addition, the conditions necessary for the manifestation of DF may be different for different types of microorganisms.

The discovery of DF is of great importance for microbiology, as it allows us to better understand the processes of reproduction of microorganisms and their behavior in various environmental conditions. It could also have practical applications in medicine and the food industry, such as developing new treatments for infectious diseases or creating more efficient food production methods.

Zdrodovsky - Sanarelli phenomenon - (z.p.z., 18.9.1891-5.5.1962, Soviet microbiologist, Honored Scientist of the Ukrainian SSR; J.S., 4.6.1865 - 28.11.1923, Italian hygienist), increased activity of procainamide in people who have previously had diphtheria in the carrier stage of tetanus, at least without any symptoms of the underlying infection. For the first time, an increase in the number of leukocytes, in many cases - leukocytosis, is observed in patients with scarlet fever. L.A. Zdrodovsky (1956) is considered a specific option. It is considered as one of the manifestations of the so-called shift reaction. From this term, introduced by F. Sanger (1879–1939) to designate changes in the leukocyte formula in tuberculosis, in consonance, apparently, proposed later by M.O. Tannenberg (1880–1972), A.A. Togunov, N.V. Popova (1985) and E.I. Kaletnik. The term “phenomenon” was used, proposed
