Microbiological aspects of the effect of Fe NPS on Wistar rats

An important route of metal intake from NP preparations is the pathway through absorption by bacterial cells of the gastrointestinal tract. This changes the composition of the microflora. Thus, giving animals NP Cu is accompanied by an increase in the total number of bacteria and lactobacilli, and a decrease in the population of E. coli and Clostridium spp. When it enters the intestine, part of the NP is able to form a pool on the inner wall of the intestine, in connection with which it can act with microorganisms inhabiting the gastrointestinal tract. The intestinal microbiota is known to play a vital role in the nutritional and immunological functions of host animals. However, in the literature there is not enough data on the influence of NP on the intestinal microbiocenosis of various representatives of the animal world and humans. The aim of the study is to study the effect of Fe nanoparticles introduced by per os on representatives of the main physiological groups of microorganisms...
