Refers to a bacterial infection anywhere in the urinary tract, such as the bladder, kidneys, ureters, or the urethra. Asymptomatic bacteriuria
1 Urinary tract infection (UTI) is a bacterial infection of the bladder, urethra, kidneys, or ureters. 2  Respiratory tract infections include sore throat, bronchitis, sinusitis, and pneumonia. 3  Bacteria or viruses may be responsible for respiratory tract infections. A bacterial infection is a proliferation of a harmful strain of bacteria on or inside the body. Bacteria can infect any area of the body. Pneumonia, meningitis, and food poisoning are just a few illnesses that may be caused by harmful bacteria. Urinary Tract Infections (UTIs). Urinary tract infections (UTIs) are a common type of infection caused by bacteria (most often E. coli) that travel up the urethra to the bladder. A bladder infection is called cystitis. If bacterial infection spreads to the kidneys and ureters, the condition is called pyelonephritis. Cystitis is considered a lower urinary tract infection. Pyelonephritis is an upper urinary tract infection and is much more serious. A urinary tract infection (UTI) is a condition in which one or more parts of the urinary system (the kidneys, ureters, bladder, and urethra) become infected. UTIs are the most common of all bacterial infections and can occur at any time in the life of an individual. References. View image. Asymptomatic bacteriuria means you have bacteria in your urine but you have no symptoms of infection. If you are healthy, this condition is usually not a problem and not something that your healthcare provider needs to check for.  Guide. A urine culture is a test to find and identify germs (usually bacteria) that may be causing a urinary tract infection (UTI) . Urine in the bladder normally is sterile-it does not contain any bacteria or other organisms (such as fungi). But bacteria can enter the urethra and cause an infection. A urine sample is kept under conditions that allow bacteria and other organisms to grow. If few or no organisms grow, the test is negative. If organisms grow in numbers large enough to indicate an infection, the culture is positive. 1 Infection of the bladder (cystitis). 2  This type of UTI is usually caused by Escherichia coli (E. coli), a type of bacteria commonly found in the gastrointestinal (GI) tract. 3  However, sometimes other bacteria are responsible. Causes. Urinary tract infections typically occur when bacteria enter the urinary tract through the urethra and begin to multiply in the bladder. Although the urinary system is designed to keep out such microscopic invaders, these defenses sometimes fail. The most common UTIs occur mainly in women and affect the bladder and urethra. 1  Infection of the bladder (cystitis). 2  This type of UTI is usually caused by Escherichia coli (E. coli), a type of bacteria commonly found in the gastrointestinal (GI) tract. 3  However, sometimes other bacteria are responsible.

This refers to a bacterial infection anywhere in the urinary tract, such as the bladder, kidneys, ureters, or the urethra. While most cases of bladder infection occur suddenly (acute), others may recur over the long-term (chronic).  In complicated cases, a longer course or intravenous antibiotics may be needed, and if symptoms have not improved in two or three days, further diagnostic testing is needed. In women, urinary tract infections are the most common form of bacterial infection with 10% developing urinary tract infections yearly. 1 Bacterial pneumonia is a bacterial infection of the lungs. 2  Urinary tract infection is predominantly caused by bacteria. 3  Symptoms include the strong and frequent sensation or urge to urinate, pain during urination, and urine that is cloudy.
