Question

Why is the type of bacteria in the urine as important as the amount of bacteria ?

Answer 1

the type of bacteria is as important as the amount as by assesing the type and amount of bacteria, one can know the type of infection and mode of the infection easily,.Escherichia coli strains are the most common isolate, founded in 80%of the urine samples of patients with a simple UTI (cystitis), followed by Staphylococcus saprophyticus (5-15%), whereas Klebsiella, Enterobacter or Proteus rarely cause infection outside the hospital (5- 10%)

Asymptomatic bacteriuria means you have bacteria in your urine but you have no symptoms of infection. ... A small number of bacteria may be found in the urine of many healthy people. This is usually considered to be harmless. However, a certain level of bacteria can mean that the bladder, urethra, or kidneys are infected.Otherwise, generally, 100,000/mL or more of a single organism reflects significant bacteriuria. The presence of multiple organisms, especially at less than 100,000/mL, typically suggests polymicrobial contamination. Yeast cells are not normally found in the urine specimen.
