What does true bacterium urine mean?

summary

What does true bacterium urine mean? True bacterial urine refers to: ① bladder puncture urine culture, bacterial growth, or colony number > 102 / ml. ② Catheterization bacteria quantitative culture ≥ 105 / ml. ③ Quantitative culture of clean midstream urine ≥ 105 / ml, one-time accuracy of 80%; The same strain was obtained by two successive cultures, the colony number was more than 105 / ml, and the accuracy was 95%.

Pathogenic bacteria any pathogenic bacteria can cause urinary tract infection, the vast majority of Gram-negative bacteria, such as Escherichia coli, paraescherichia coli, proteus, Pseudomonas aeruginosa, aerogenic bacteria and so on. About 85% of acute and uncomplicated urinary tract infections are caused by Escherichia coli. Coccal infection is rare, such as Staphylococcus and Streptococcus faecalis, mainly coagulase negative Staphylococcus albicans or saprophytic Staphylococcus. In the past, this kind of bacteria was considered as non pathogenic bacteria. Due to the wide application of broad-spectrum antibiotics, the incidence rate of fungal urinary tract infections is increasing. Viruses can also cause urinary tract infections, such as adenoviruses, which can cause hemorrhagic cystitis in boys.

① Bladder puncture urine culture, bacterial growth, or colony number > 102 / ml. ② Catheterization bacteria quantitative culture ≥ 105 / ml. ③ Quantitative culture of clean midstream urine ≥ 105 / ml, one-time accuracy of 80%; The same strain was obtained by two successive cultures, the colony number was more than 105 / ml, and the accuracy was 95%; If the colony number of bacteria cultured in the middle urine is between 104 and 105 / ml, it is considered suspicious and should be repeatedly cultured; If it is cocci, the number of colonies cultured in midstream urine is more than 200 / ml.

Asymptomatic bacteriuria: also known as occult bacteriuria, is a kind of occult urinary tract infection, that is to say, the patient has genuine bacteriuria (the bacterial quantitative culture of clean midstream urine is more than 105 / ml for two consecutive times, and the strains are the same for two times, and the false-positive results are definitely ruled out) without any symptoms of urinary tract infection, but in some cases, slight symptoms can be found after careful inquiry. The bacteria come from the kidney or bladder. The incidence rate of incidence of asymptomatic bacteriuria is higher than that of those with symptoms. The incidence rate of 4% of the 16~65 year old women is 0.5%, while that of male patients is 0.5%. In female patients, 1/4 bacteria urine can disappear, but new bacterial urine is also constantly occurring. So the incidence rate of 4% is quite constant.

matters needing attention

Avoid contamination: the most common bacteria causing infection is Escherichia coli. Under normal circumstances, it parasitic in the intestinal tract, does not cause disease, but if the anus into the urethral orifice, it will lead to urethral inflammation. So after defecation, wipe with clean toilet paper, according to the order from front to back, so as not to pollute the vaginal opening. If the toilet has flushing equipment, it is best to wash the anus carefully. Vitamin C Supplement: Vitamin C can improve the acidity of urine, so that a variety of bacteria induced urinary tract infection is not easy to survive. Therefore, drink orange juice, citric acid, kiwi juice and other vitamin rich drinks to prevent urinary tract infection.
