Bacteriuria is the presence of bacteria in urine. [1] Bacteriuria accompanied by symptoms is a urinary tract infection while that without is known as asymptomatic bacteriuria. [1] [2] Diagnosis is by urinalysis or urine culture. [3] Escherichia coli is the most common bacterium found. [1]
The interpretation of urinalysis takes into account the results of physical, chemical and microscopic examination and the person's overall condition. Urine test results should always be interpreted using the reference range provided by the laboratory that performed the test, or using information provided by the test strip/device manufacturer.

Aerococcus urinae is a member of the bacterial genus Aerococcus.The bacterium is a Gram-positive, catalase-negative coccus growing in clusters. Isolates of this genus were originally isolated in 1953 from samples collected in the air and dust of occupied rooms and were distinguished by their tetrad cellular arrangements. [2]
Pyuria is the condition of urine containing white blood cells or pus. Defined as the presence of 6-10 or more neutrophils per high power field of unspun, voided mid-stream urine, it can be a sign of a bacterial urinary tract infection. Pyuria may be present in people with sepsis, or in older people with pneumonia.
A urine sample that tests positive for both nitrite and leukocyte esterase should be cultured for pathogenic bacteria. [citation needed] "It has been proposed that the reagent strip for leukocyte esterase designed for the testing of urine (Combur test UX) could be a useful tool for diagnosing spontaneous bacterial peritonitis (SBP)."
The Paris System for reporting urine cytology, version 2.0, ranging from negative to positive for high grade urothelial carcinoma. [1] Urine cytology is a test that looks for abnormal cells in urine under a microscope. The test commonly checks for infection, inflammatory disease of the urinary tract, cancer, or precancerous conditions.
Rates of asymptomatic bacteria in the urine among men over 75 are between 7–10%. [11] 2–10% of pregnant women have asymptomatic bacteria in the urine and higher rates are reported in women who live in some underdeveloped countries. [108] Urinary tract infections may affect 10% of people during childhood. [7]
Staphylococcus saprophyticus was not recognized as a cause of urinary tract infections until the early 1970s, more than 10 years after its original demonstration in urine specimens. Prior to this, the presence of coagulase -negative staphylococci (CoNS) in urine specimens was dismissed as contamination.
