Transition of entheropathogenic and saprotrophic bacteria in the eco-niche cycle: animals-excrement-soil-plants-animals

The possibility of transition of saprotrophic and enteropathohenic bacterial populations following the chain of naturally related habitats--fodder-animal gastrointestinal tract (GIT)-animals excrement-soil-plants and again animals with a cyclic formation--has been investigated quantitatively.

Summary:The possibility of transition of saprotrophic and enteropathohenic bacterial populations following the chain of naturally related habitats--fodder-animal gastrointestinal tract (GIT)-animals excrement-soil-plants and again animals with a cyclic formation--has been investigated quantitatively. All bacteria used in the experiments have been shown to successfully overcome all the mechanical, physical-chemical, and biological barriers in the food chain and to come out into the environment with a quite high number. It has been demonstrated that the same bacterial population can pass the whole cycle without additional introduction of similar populations from the outside.
