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. [110] Urinary tract infections may affect 10% of people during childhood. [7]
Bacteriuria is assumed if a single bacterial species is isolated in a concentration greater than 100,000 colony forming units per millilitre of urine in clean-catch midstream urine specimens. [16] In urine samples obtained from women, there is a risk for bacterial contamination from the vaginal flora.
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.
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]
Purple urine bag syndrome typically occurs as a result of bacterial infections. Thus, taking precautions against the development of bacterial infections can minimize the risk of purple urine bag syndrome. Drinking lots of water can help with preventing the development of UTI's that promote the growth of bacteria involved in purple urine bag ...
Polyuria (/ ˌ p ɒ l i ˈ jʊər i ə /) is excessive or an abnormally large production or passage of urine (greater than 2.5 L [1] or 3 L [6] over 24 hours in adults). Increased production and passage of urine may also be termed as diuresis.
Urine is typically clear; materials such as crystals, cells, bacteria, and mucus can impart a cloudy appearance. [26] A milky appearance can be caused by a very high concentration of white blood cells or fats, or by chyluria (the presence of lymphatic fluid in the urine). [34] Unpreserved urine will become cloudier over time. [35]
