[An epidemiological assessment of the results of laboratory research on environmental objects]

On the basis of the experience in antiepidemic protection of troops several methods were worked out to make epidemiological estimation of laboratory researches which were conducted in order to disclose the risk factors that provoke infectious diseases. The main attention was focused on the problem of intestinal infections. It was stressed that the practical evaluation of fecal pollution index of water had to be done taking into account the level of infectious morbidity. In unsatisfactory indices of colimetry a threat of diseases in troops is much higher in the regions with frequent intestinal infections. In unfavourable regions with high viral intestinal infections the studies of water must be done after its purification and decontamination in order to reveal the presence of coliphages. On the basis of catering objects the article gives methods for differential estimation of the results of colon bacillus tests depending on epidemiological signification of environmental objects.
