Bacteriuria is the presence of microorganisms in the newly urine. Flora by bacteriuria different - E. coli, Staphylococcus, Streptococcus, Proteus, Pseudomonas aeruginosa, etc., In most cases of bacteriuria - inflammatory symptom of kidney damage (see Pyelonephritis) or one of the divisions urinary system urinary bladder and the urethra and prostate gland and seminal vesicles. Bacteriuria occurs in patients who have had some infectious disease. Often bacteriuria occurs among patients long-term constipation. Colibacillosis bacteriuria often occurs in patients with diseases of the colon, when the proktit, anal fissures. Bacteriuria is possible in the presence in the body of other foci of infection, of which microbes do hematogenous or lymphogenous by the kidneys and urinary tract. If bacteriuria may be increased urination and cloudy urine, sometimes with sediment. In the presence of bacteriuria is necessary to conduct a thorough urological examination to establish the source of her and timely treatment of the disease that caused the bacteriuria. Carriers of the infection after suffering typhoid may not be allowed to work in the food enterprises and institutions.

Bacteriuria (bacteria and Greek. uron - urine) - the presence of microorganisms in the newly urine. There are bacteriuria true, in which microbes beetroot and breed in the urinary tract, and false when microbes pass into the urine from the blood via the kidney, not reproducing themselves. The bacteria can get into the urine different ways: top-down - from inflammatory lesions of the kidneys, prostate glands and the rear part of the urethra; ascending - by instrumental studies (catheterization, birovni), limfocitarnyi - of genital organs, intestines with long-term constipation, enterocolitis, proctitis, cracked rear passage; hematogenous - in infectious diseases (typhoid fever, brucellosis, leptospirosis, erysipelas, influenza) and of the foci of infection in the body (tonsillitis, and so on). Depending on the form of bacteriuria in urine find Escherichia coli, Staphylococcus, Streptococcus, Proteus, sarcini, micrococci etc. in pure culture or mixed flora (Fig). Bacteriuria is often detected in healthy people, because in the urethra always vegetates microflora.
In some cases, asymptomatic bacteriuria, in the other - by type of cystitis, pyelonephritis. There are low-grade fever, a breach of urination. Urine becomes turbid because of the large number of microbes, when standing and centrifugation is formed with difficulty or not formed. Reaction urine different depending on flora. Diagnosis of bacteriuria is established by microscopy urine sediment, urine culture, and also accelerated method (triphenyltetrazolium chloride), proposed by Simmons and Williams (N. A. Simmons, J. D. Williams, 1962). The prognosis for B. in most cases favourable.
Treatment - pathogenetic: elimination of the source of infection in the body, antibiotics, nitrofurans and sulfa drugs, increasing reaction forces of the organism, the elimination of disturbed passage of urine, diet and health resort treatment.
Epidemiological significance of bacteriuria. B. is of epidemiological importance in a limited number of infectious and invasive diseases. The danger media for the surrounding determined by the solidity and duration of allocation of the pathogen with urine, peculiarities of the mechanism of transmission for this disease sanitary culture media, the state sanitary-and-municipal improvement.
The bacteriuria is often observed in patients with typhoid fever (over 30%). The convalescents exciter with urine out relatively rare. However, the media infects the environment, and this can lead to occurrence of diseases. Not less than 10% of patients with brucellosis occurs B. When this pathogen in the urine detected within 2 weeks after infection, but more often planted at the end of the febrile period and during convalescence. Carriage of several possible in 3-5 years. At hit in urine water and food can be infected people and Pets.
Leptospira in urine detected during a month or more. The most dangerous in an epidemiological sense penetration of leptospires urine in freshwater water bodies used for household and economic purposes. In rare cases bacteriuria possible in patients tularemia, tuberculosis, diphtheria, dysentery and other bacterial infections. Epidemiological is it when these diseases is negligible. The pathogen was found in the urine of some viral and riccetsios infections. In epidemiological terms, this phenomenon is not well understood. There are indications of the possibility of contamination of water at epidemic hepatitis (Botkin's disease). The urine excreted eggs of helminths (urogenital schistosomiasis, sparganosis, dictophones).

Bacteriuria and colibacillosis; b - staph; 1 - E. coli; 2 - leukocytes; 3 - epithelial cells; 4 - amorphous phosphates and tripolyphosphate; 5 - staphylococci.
