It may occur in the case of diseases of the urinary tract, reproductive system and diseases of the abdominal organs. [6] Leukocyturia is mostly a sign of urinary tract infection, especially if significant bacteriuria is found (for most people, the number of bacteria in a culture is > 10^5) and other symptoms associated with passing urine. [7]
A negative dipstick test does not exclude bacteriuria, as not all bacteria which can colonise the urinary tract are nitrate-reducing. The leukocyte esterase test indirectly detects the presence of leukocytes (white blood cells) in urine which can be associated with a urinary tract infection. In the elderly, the leukocyte esterase test is often ...
Swarming cells are only formed when the bacteria are grown on solid surfaces so the ability to detect these solid surfaces is a required feature. It has been proposed that Proteus mirabilis senses a solid surface by the inhibition of its flagellum rotation, and it is this lack of freely rotating flagella that let the bacteria know it is on a ...
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]
Proteus is a genus of Gram-negative bacteria. It is a rod shaped, aerobic and motile bacteria, which is able to migrate across surfaces due its “swarming” characteristic in temperatures between 20 and 37 °C. [1] Their size generally ranges from 0.4 to 0.8 μm in diameter and 1.0–3.0 μm in length. They tend to have an ammonia smell. [2]
GBS urinary tract infections, more than 100.000 CFU (colony forming units) /mL, may induce labour in pregnant women and cause premature delivery (preterm birth) and miscarriage and requires antibiotic treatment. The presence of GBS in the urine in any colony count is a marker of heavy GBS colonization and an indication for Intrapartum ...
S. saprophyticus causes 10–20% of urinary tract infections (UTIs). In females 17–27 years old, it is the second-most common cause of community-acquired UTIs, after Escherichia coli. [5] Sexual activity increases the risk of S. saprophyticus UTIs because bacteria are displaced from the normal flora of the vagina and perineum into the urethra ...
It is known to cause wound infections and other species of its genera are known to cause urinary tract infections. P. vulgaris was one of the three species Hauser isolated from putrefied meat and identified (1885). Over the past two decades, the genus Proteus, and in particular P. vulgaris, has undergone a number of major taxonomic revisions.
