At research of blood plasma by scanning electronic microscopy in group of 67 practically healthy inhabitants of Blagoveshchensk in 77.6% of cases asymptomatic bacteremia, i.e. translocation of elementary bodies of L-forms bacteria was found out and only in 22.4% of the citizens it was not visualized. The same changes were also revealed in 2 practically healthy gold miners working in difficult environment. Presumably, the translocation of elementary bodies of bacteria occurs owing to the moderate infringement of microbic landscape of thick intestines and insignificant dysfunction of intestines barriers, and it inherently proves poor health of respondents.
