Sažetak
The microbial population represents a group of heterogeneous germs comprising several different species which live and act together in the same place. The communities of micro-organisms, as independent population groups, are better adapted for growing than a unique species.
The microbial flora of the puerperal uterus differs from case to case, being represented both as bacteria admitted as pathogenic and particular tropism for the uterine morphological structures and opportunist bacteria which are quite numerous.
Here are some of the microbial identified species: Streptococcus spp., E.coli, C.pyogenes . These exercise the pathogenic action under certain circumstances such as: the existence of these germs in big quantities, virulence and the high rate of pathogenity, the low resistence of the body.
The experimental and epidemiological observations have proved the fact that autochthonous microorganisms (the normal, permanent microflora), adapted to develop in certain natural habitats, exercise a barrier function which protects the animal organisms from the implantation of several microorganisms which penetrate in the
outer environment.
The necrotic processes at the level of the uterine mucous membrane were at different stages of evolution in all the cases in question with big or even huge differences from one geographical area to another one.
In some geographical areas the alternative processes were obvious only at the surface of the mucous membrane, with the affecting of the cells and area placed close under the basic membrane, while the
epithelium although it seemed obviously affected, was not detached from the basic membrane.
The cells of the uterine mucous membrane seemed detached here and there either under the form of groups taking up small areas, or in big areas alternating with zones where the epithelium was still partially preserved and, eventually extensive areas, completely without mucuos membrane, where even traits of cells at the level
of the mucous membrane could not be noticed.
