THE MICROFLORA OF THE BODY OF THE PERSON

On microbic structure at the person the sex, age, food stuffs, a climate, use of medical products can render influence.

The microflora shares on 2 groups:

1. a constant (resident) - nonpathogenic bacteriums on a skin and in perigastriums;
2. facultative (transitional) - nonpathogenic and pathogenic.

the Microflora of a skin.

Nonpathogenic: sartsiny, diphtheroids, musty and Ascomycetes, Staphylococcus epidermis, micrococcuses.

Pathogenic and conditional - pathogenic: E. coli - testifies to fecal contamination of a skin, Staphylococcus aureus, a hemocatheretic and not hemocatheretic streptococcuses, klostridii a tetanus, musty, barmy and imperfect funguses, spores of aerobic and anaerobic bacillus. Most arms are frequently infected. The pathogenic microflora of a skin can invoke pustular and mycotic affections.

the Microflora of an oral cavity.

Dwells more than 100 kinds of bacteria.

Nonpathogenic: Str. salivarius, str. mitior, funguses Candida, nejsserii, actinomyces, laktobakterii.

Pathogenic: anaerobic bacteroids, fuzobakterii, vejllonelly, actinomyces, spirochetes of labors Leptospira, Borrelia, Treponema, mycoplasmas.

the Microflora of wind - pipes.

The most part of microbes is late in a nasal chamber, in terminal bronchioles and alveoluses of microbes practically is not present.

In a nasal chamber a hemocatheretic micrococcus, diphtheroids. Staphylococcuses, streptococcuses, saprophytic Gr-diplokokki, protej, Haemophilus influenzae, many viruses, including adenoviruses. On microbes render bactericidal action a mucin and a lysozyme. The nasopharynx contains not hemocatheretic and zelenjashchie streptococcuses, nonpathogenic nejsserii, stafillokokki and enterobakterii, and also meningokokki, pyogenic streptococcuses, pneumococcuses, the originator of a pertussis.

the Microflora of genitourinary system.

The top departments (kidneys, ureters) in norm are sterile. In a urethra - streptococcuses, peptokokki, korinebakterii, bacteroids, micobacteria, Staph. epidermis, diphtheroids, funguses of labors Candida, Torulopsis, Geotrichum. In outside departments Mycobacterium smegmatis. The vagina contains rods Doderlejna, Str. agalactiae.

the Microflora of a gastrointestinal tract.

In a gastrointestinal tract>260 kinds. Basically anaerobes.

In a stomach of bacteria it is not enough (no more than 1000/ml). There are lactic asid bacteria, Sarcina ventriculus, Bac. subtilis, yeast. Dysenteric, typroid, paratyphoid bacteria, a cholera, etc. the pathogenic microorganism can penetrate.

In a thin intestine it is little bit more, than in a stomach. There are anaerobes, protej, funguses, Str. faecalis.

In a thick intestine it is a lot of (1012/ã faecal matters). E. coli (including pathogenic serovars), bifidobakterii, bacteroids, laktobatsilly, enterokokki, staphylococcuses, enterokokki, Clostridium perfringens, Proteus vulgaris.

Bacteria of mucosas of eyes - staphylococcuses, mycoplasmas, Corynebacterium xerosis. At infringements - can invoke konjuktivity, blepharites.

Infringement of a species composition of a normal microflora under influence of the various factors, described by change of a ratio of various kinds of bacteria - a dysbacteriosis.

The content bifidobaktery is usually sharply reduced, the content of staphylococcuses, including hemocatheretic, Candida, the changed intestinal rods,

Dysbacterioses as a rule meet in an intestine.

Crops study on presence of the pathogenic microorganism and on infringement of ratios of a microflora. For enrichment recommend to use mediums of the Mjullera-coat-of-mail shell, selenitovyj a broth, magnesian medium, for cultivation - mediums Ploskireva, Endo and Levin, mediums TSejsslera, Saburo, Blaurokka, triglikolevyj a broth. Pathogenic bacteriums determine on mediums with antibiotics; researches on a dysbacteriosis carry out for reception of the basic criteria and parameters. Results should be counted objective at the analysis of body height of isolated colonys at which it is possible to count up total on cup Petri. At continuous body height the analysis should be repeated, effecting a seeding from the big delutions. Facultative bacteria cultivate 24-48 ch at 37 ° With, bifidobakterii - 48 ch, anaerobes and bacteroids - 4-5 day in anaerostate, crops on medium Saburo - 96 ch at 28-30 ° S.Posle identifications effect recalculation of content MO of everyone taksonomicheskoj groups on 1 g a researched material.

It is necessary to approach to an evaluation of results cautiously since the structure of an intestinal microflora is subject to various fluctuations and it is necessary to distinguish a true dysbacteriosis from disbakterialnyh reactions (alterations in structure of a microflora are insignificant or short-term and do not demand specific correction). At a true dysbacteriosis of infringement of a microbic coenosis usually correlate with clinical exhibitings, and their normalization is long enough (20-30 day).

At carrying out of repeated researches it is necessary to reflect available positive or negative alterations.
