What does positive bacteria in urine mean?

What is the most common bacteria found in urine?
The most common bacteria found to cause UTIs is Escherichia coli (E. coli). Other bacteria can cause UTI, but E. coli is the culprit about 90 percent of the time.
What causes E. coli to grow in urine?
coli often gains entry into the urinary tract via stool. Women are particularly at risk for UTIs because their urethra sits close to the anus, where E. coli is present. It’s also shorter than a man’s, giving the bacteria easier access to the bladder, where the majority of UTIs occur, and the rest of the urinary tract.
What is Enterococcus species in urine?
Enterococcus faecalis is a gram-positive bacterium that can cause a variety of nosocomial infections of which urinary tract infections are the most common. These infections can be exceptionally difficult to treat because of drug resistance of many E. faecalis isolates.
Does Enterococcus in urine need to be treated?
If you have enterococci in your body but they’re not causing an active infection, you don’t need treatment. Active VRE infections are treated with an antibiotic that’s not vancomycin. Your doctor can take a culture of the bacteria and have it tested in a laboratory to see which antibiotic might work best.
How common is Enterococcus UTI?
Enterococci have become an increasingly common cause of UTI, accounting for greater than 30% of all bacterial isolates causing UTI among hospitalized patients.
Does bacteria in urine always mean UTI?

What causes Enterococcus bacteria?
Enterococcus faecalis is a bacteria that lives in the gut and is eliminated in feces. Infection is caused by fecal-oral transmission (spread of infection from feces to the mouth) and cannot be transmitted by coughing or sneezing.
