The Structure of Conditionally Pathogenic Microflora, Isolated From the Urogenital Tract of Women With Pathological Course of Pregnancy

Abstract

The structure of the microflora of the urogenital tract of a woman is variable and diverse, changing its qualitative and quantitative composition can affect various physiological processes in the body of a woman, including the course of pregnancy. In this study, the results of cultures of 1415 samples of urine and cervical canal discharge of pregnant women were analyzed. Species identification was carried out by MALDI-ToF mass spectrometry using Microflex LT (Bruker) mass spectrometer. Gram-positive bacteria (69.5%) dominated the structure of the cervical canal microflora, among which Staphylococcus spp prevailed., Enterococcus spp. and Lactobacillus spp. Among gram-negative bacteria most often encountered microorganisms of the order Enterobacteriales, the predominant species among which was E. coli. Also, yeast-like fungi were isolated from the material of the cervical canal, their number was 11% of the total number of crops. Qualitative microbiological composition of urine was represented by gram-positive flora (68.7%), gram-negative flora (30.1%) and Candida fungi (1.2%). There is a significant predominance of coagulase-negative staphylococci (97.3%) over coagulase-positive (2.7%) in the structure of gram-positive microorganisms. The composition of gram-negative flora is mainly represented by bacteria of the order Enterobacteriales (71.4%). The study identified microorganisms that can cause postpartum complications and the development of inflammatory diseases of the newborn, which suggests the need for regular microbiological examination for pregnant women.
