Mixed flora in urine culture may be caused by a number of factors, including: -The time between sample collection and laboratory processing can allow small amounts of contaminating bacterial flora to multiply up to higher amounts prior to laboratory testing, which can result in heavy mixed growth of bacteria on culture.-Poor hygiene practices can introduce bacteria into the urinary tract and lead to contamination of the urine sample.-If the patient has a sexually transmitted infection, this can also lead to the growth of multiple types of bacteria in the urine sample. If I am understanding mixed Flora correctly, I believe it is bacteria contamination. 5 What does it mean to have mixed urogenital flora? Current treatments include combinations of topical or systemic antibiotics, corticosteroids, and diluted bleach baths. Surveillance criteria may not be equally sensitive for all patient populations. Unlike single-dose antibiotic therapy, a three-day regimen reduces rectal carriage of gram-negative bacteria and is not associated with a high recurrence rate. However, sparfloxacin can cause phototoxicity, and it has also been associated with prolongation of the QT interval.17. What information is needed to assist with UTI determination? The full algorithms for reporting are complex and vary to some extent among labs, but certain principles are common to all: The goal of these algorithms is to ensure that bacteria that are causing disease are accurately reported so that patients can be treated, while avoiding unnecessary reporting of bacteria that are very unlikely to be causing a UTI in order to avoid excessive antibiotic use. You can review and change the way we collect information below. CDC twenty four seven.

The E. coli #1 and #2 is considered one organism, similarly Enterococcus species #1 and Enterococcus species #2 would be considered one organism. Its also important to note that asymptomatic bacteriuria, or the presence of bacteria in the urine of a person who is not having UTI symptoms, does not require treatment in most cases (pregnant women are an exception), so urine cultures should not generally be obtained in people in the absence of UTI symptoms. Patient populations in which the UTI criteria may not be as sensitive include spinal cord injury patients, those with brain injuries, and heavily sedated patients. Potential probiotic treatments include using the commensal skin bacteria, S. epidermidis, to inhibit S. aureus growth. What does this mean? Occasionally, lower quantitative counts may be encountered in patients who are undergoing diuresis or who are in renal failure. However, if they do manage to establish themselves and cause an infection, treatment with antibiotics may be necessary.
