The accumulation of materials on the viability of microbes has moved along three channels observation of flare-ups of epidemics experimental checking of the viability of parasitic microbes under laboratory conditions and checking the viability of parasitic microbes under field conditions. The viability of parasitic microbes can be clarified corrently only with consideration of the interaction of the organism with the environment and adaptation to it. According to this school of thought, the stability of a causative agent in the environment is determined by the specific mechanism through which they are transferred from one organism to another. The following rule is general and adequately substantiated the more highly perfected the mechanism of transfer of the contaminating principle, the shorter the period during which the parasitic microbe is in the environment - i.e., the mechanism of transfer of infection predetermines the degree of stability of the microbe. On the basis of these positions the author considers the stability of the agents of the basic groups of infections in the environment.
