A urinary tract infection (UTI) is an infection that affects a part of the urinary tract. [ 1 ] Lower urinary tract infections may involve the bladder (cystitis) or urethra (urethritis) while upper urinary tract infections affect the kidney (pyelonephritis). [ 10 ] Symptoms from a lower urinary tract infection include suprapubic pain, painful ...
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 ] People without symptoms should generally not be ...
Urinalysis is one of the most commonly performed medical laboratory tests. [ 12 ] It is frequently used to help diagnose urinary tract infections [ 13 ] and to investigate other issues with the urinary system, such as incontinence. [ 14 ] It may be used to screen for diseases as part of a medical assessment.
Serratia marcescens (/ səˈreɪʃiəmɑːrˈsɛsɪnz /) [ 3 ][failed verification] is a species of rod-shaped, Gram-negative bacteria in the family Yersiniaceae. It is a facultative anaerobe and an opportunistic pathogen in humans. It was discovered in 1819 by Bartolomeo Bizio in Padua, Italy. [ 4 ]S. marcescens is commonly involved in ...
Analysis of the urine may show signs of urinary tract infection. Specifically, the presence of nitrite and white blood cells on a urine test strip in patients with typical symptoms are sufficient for the diagnosis of pyelonephritis, and are an indication for empirical treatment. Blood tests such as a complete blood count may show neutrophilia.
Proteus mirabilis is a Gram-negative, facultatively anaerobic, rod-shaped bacterium. It shows swarming motility and urease activity. P. mirabilis causes 90% of all Proteus infections in humans. It is widely distributed in soil and water. [ 1 ]Proteus mirabilis can migrate across the surface of solid media or devices using a type of cooperative ...
Staphylococcus pseudintermedius is a gram-positive spherically shaped bacterium of the genus Staphylococcus [ 1 ] found worldwide. [ 2 ] It is primarily a pathogen for domestic animals, [ 3 ] but has been known to affect humans as well. [ 4 ]S. pseudintermedius is an opportunistic pathogen that secretes immune-modulating virulence factors, has ...
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]
