METHOD OF ESTIMATING MICROBIAL RISK OF DEVELOPMENT OF BACTERIAL INTESTINAL INFECTIONS TRANSMITTED BY WATER WAY IN CASE OF DIRECT RELEASE OF CAUSATIVE AGENT OF ACUTE INTESTINAL INFECTIONS FROM WATER INTENDED FOR DIFFERENT PURPOSES Russian patent published in 2012 - IPC G01N33/18 C12Q1/00 

FIELD: medicine.

SUBSTANCE: bacteriological analysis of water by normalised indicators is performed with determination of pathogenic bacteria, additionally during water analysis determined are potentially pathogenic bacteria and their pathogenic and virulent properties, obtained data are used to estimate probability of infectious process development in people by formula: H_patogen ⁼(C•(100-P_t)•V•v/r)•T. After that, calculated is integral index of probability of development of bacterial intestinal infections transmitted by water way with direct release of causative agents isolated and identified during microbiological analysis of water by formula: After that, risk of development of bacterial intestinal infections transmitted by water way is carried out, it is considered to be acceptable if its value does not exceed 1x10^-5, and microbial risk of development of bacterial intestinal infections transmitted by water way is considered to be low. If its value is from 1x10^-5 and lower, microbial risk of development of bacterial intestinal infections transmitted by water way is considered to be high. If its value constitutes more than 1x10^-5, risk of water contamination with pathogenic and potentially pathogenic microflora is estimated at population level by formula: R_p=R_v•100000.

EFFECT: application of claimed method makes it possible to reduce or prevent development of intestinal diseases and makes it possible to predict probability of BII development with direct release of bacterial causative agents from water for various purposes, taking into account their species composition and biological properties.
