What does 100000 CFU mL mixed flora mean?

When 3 or more types of bacteria grow and no single one predominates (i.e., none is present at >100,000 CFU/mL), the results may be reported as “mixed bacterial flora.”

What does urine culture urogenital flora mean?

The urine culture is a test that detects and identifies bacteria and yeast in the urine, which may be causing a urinary tract infection (UTI).

Is 100000 CFU mL a UTI?

Young, sexually active women often experience symptoms of UTI with colony counts less than 100,000 CFU/mL. In this setting, the presence of pyuria and a colony count less than 100,000 CFU/mL are sufficient to diagnose a clinically significant UTI.

Is urogenital flora normal?

One study of normal volunteers showed a marked variation in introital organisms mediated by changes in urinary frequency. It is estimated that, at some point in time, up to 78% of women will have an “unhealthy” flora although they are free of symptoms.

Is commensal flora in urine a UTI?

The pathogen: the commensal flora. UTI is frequently caused by organisms which are normal commensals in the distal urethra and adjacent sites. The most common route of infection is by ascension. The well-recognized gender difference in the prevalence of UTI is clearly related to the short length of the female urethra.

How much urogenital flora is normal?

However, in the process of collecting the urine, some contamination from skin bacteria is frequent. For that reason, up to 10,000 colonies of bacteria/ml are considered normal. Greater than 100,000 colonies/ml represents urinary tract infection. For counts between 10,000 and 100,000, the culutre is indeterminate.

What does it mean if commensal flora is present?

Commensal microflora (normal microflora, indigenous microbiota) consists of those micro-organisms, which are present on body surfaces covered by epithelial cells and are exposed to the external environment (gastrointestinal and respiratory tract, vagina, skin, etc.).
