These occur most frequently in women for anatomical reasons such as the proximity of the urethra with the vagina and year-round, as well as the fact that being the shortest female urethra is easier than the bacteria from accessing this via the urinary system.
The results of the urine are reported as colony-forming units per milliliter (cfu/ml). The most frequently isolated bacteria are Escherichia coli, Proteus and Klebsiella, in people with poorly controlled diabetes are more common germs like the Pseudomona.
The importance of practicing the urine culture is that allows you to indicate a specific treatment whereupon the certainty that will eradicate the infection can be, stated empirically treatments can lead to an incorrect antibiotic choice well because the causal agent is not an Escherichia coli, which is the most common cause of these infections , or because there is bacterial resistance to the antibiotic indicated which leads to not go away the infection.
