What does resident flora mean in a urine culture?
The microorganisms that usually occupy a particular body site are called the resident flora. Cells of the resident flora outnumber a person's own cells 10 to 1. Microorganisms that colonize people for hours to weeks but do not establish themselves permanently are called transient flora.
What is a resident flora?
The resident flora (resident microbiota) consists of microorganisms residing under the superficial cells of the stratum corneum and can also be found on the surface of the skin.
What is positive flora in urine?
Gram-positive bacteria are a common cause of urinary tract infection (UTI), particularly among individuals who are elderly, pregnant, or who have other risk factors for UTI.
Is flora normal in urine?
With these expanded tests, 52 out of 65 patient samples grew bacteria, while traditional culture methods deemed 95% of them negative. These results led the researchers to conclude that the urinary tract does, in fact, have normal flora and that urine is not sterile.
Is resident flora easily removed?
Transient flora are easily removed by hand washing. Resident flora are attached to the deeper layers of the skin and are more difficult to remove. Resident flora are less likely to be associated with infection.
Is resident flora pathogenic?
As mentioned, resident and transient bacteria aren't inherently pathogenic, so what leads them to cause an infection? The Staphylococcus genus is one of the most common resident bacteria in our bodies. However, the Staphylococcus aureus bacteria is more pathogenic than Staphylococcus epidermidis.
What does it mean when a urine culture showed mixed flora?
If the urine is not collected in a sterile manner the urine sample may be 'contaminated' by bacteria that originate from the skin or genital area, and not from the urinary tract. This is often described by the clinical laboratory as 'mixed growth bacteria'.
How do you know if a UTI has spread to your kidneys?
A kidney infection is, in essence, a UTI that has spread into the kidneys.

Fever, shaking or chills.
Is normal flora harmful?
Even though most elements of the normal microbial flora inhabiting the human skin, nails, eyes, oropharynx, genitalia, and gastrointestinal tract are harmless in healthy individuals, these organisms frequently cause disease in compromised hosts.
How do I get rid of resident flora?
Washing with detergent or plain soap is usually sufficient for the removal of transient flora although repeated handwashings may be necessary if the hands are exceptionally soiled or if contamination has been rubbed in.
How do resident flora affect human health?
The normal flora prevent colonization by pathogens by competing for attachment sites or for essential nutrients. This is thought to be their most important beneficial effect, which has been demonstrated in the oral cavity, the intestine, the skin, and the vaginal epithelium.
Is mixed flora in urine an infection?
Urine cultures that contain more than one organism are usually considered contaminated. The frequency with which such growth truly represents mixed infection is unknown. Surprisingly few studies have evaluated the clinical significance of polymicrobial growth from urine.
What does mixed flora in urine mean?
Because “mixed flora”* implies that at least 2 organisms are present in addition to the identified organism, the urine culture does not meet the criteria for a positive urine culture with 2 organisms or less. Such a urine culture cannot be used to meet the NHSN UTI criteria.

What is the importance of normal flora in the urinary tract?
One promising alternative is the use of live microorganisms (probiotics) to prevent and treat recurrent complicated and uncomplicated urinary tract infection (UTI). The human normal bacterial flora is increasingly recognised as an important defence to infection.
Is mixed flora a UTI?
The isolation of more than one microorganism from a single urine specimen; mixed flora is known as polymicrobial bacteriuria and the associated condition is polymicrobial UTI.

Can a normal flora be harmful?
Even though most elements of the normal microbial flora inhabiting the human skin, nails, eyes, oropharynx, genitalia, and gastrointestinal tract are harmless in healthy individuals, these organisms frequently cause disease in compromised hosts.
How do residential flora affect human health?
These normal flora provide us with many benefits, which include: They prevent colonization by pathogens by competing for attachment & nutrients. Some synthesize vitamins that are absorbed as nutrients by the host (e.g. K & B12). Some produce substances that inhibit pathogenic species.
