Combined Drug with Antibacterial Effect Supports the Normal Intestinal Microflora

  • Published:
Bulletin of Experimental Biology and Medicine Aims and scope

Widespread use of antibiotics leads to an imbalance of normal intestinal microflora and to the development of multidrug resistance. The problem can be solved by administration of the antibiotics in combination with the drugs that have an immunotropic effect. We studied the effect of the drug containing technologically processed affinity purified antibodies to IFNγ, CD4 receptor, β2-microglobulin of MHC class I, and β2-domain of MHC II combined with antibiotics on the composition of intestinal microflora of pigs and the total number of microbiome resistance genes. Using the methods of NGS sequencing and quantitative PCR, we found that the drug contributes to the maintenance of normal microflora and, consequently, to the symbiotic relationship of the host with microflora, and prevents the reproduction of pathogenic bacterial species. Analysis for the presence of the resistance genes of gastrointestinal microorganisms showed that the drug does not affect the qualitative and quantitative composition of these genes of the intestinal microbiome.
