The gravitational mass spectroscopy (GMS) method was used to remotely study the gravitational noise (GN) from the distant molecular energy order of atomic nuclei clusters (ANC) in the microflora of the gastrointestinal tract (GIT) of a 72-year-old probant. GN from ANC – the genomes of the most important bacteria were registered in the stomach, small intestine, umbilical cord, rectum, and also in urine. The energy characteristics of the genomes of the most important bacteria of the gastrointestinal tract were studied: E-coli, Bacteroides fragilis NCTC 9343, Prevotella melaninogenicus, Bacteroides oralis, Enterobacter sp., Clostridium perfringens, Staphylococcus aureus, as well as Bacteriophage T4 (Escherichia virus) and Bacteriophage, vB_BfrS_NCTC. Signals of genomes in different conformations have been detected, providing insight into the activity of bacteria in real time and the space they occupy in the gastrointestinal tract. The distribution of bacteria in the gastrointestinal tract is not uniform, and the serotype composition of bacteria in GIT is not uniform either. Genomes, as ANC in the studied ensemble of masses from 50 Da to 3.4 billion Daltons, are subject to the general energy of the ensemble of masses in this interval. Minimization of potential energy in the ensemble forces the fragmentation of genomes and their reorganization, which in turn leads to the emergence of many bacterial serotypes. It has been shown that the penetrating ability of bacteria depends on both their shape and size, and on the activity of Bacteroides fragilis, which causes stretching of the intercellular space in the tissues of the gastrointestinal tract and, further, gas gangrene. The activity of this bacteria is controlled by the Bacteriophage, vB_BfrS_NCTC. The reason for genomes entering the genitourinary system has been established. A model of the process of bacterial infiltration from the gastrointestinal tract into the ureter tissues has been given.
