Every day urinary infections are greater and affect children, young people, adults and the elderly, we have high urinary infections (pyelonephritis) and low (cystitis, urethritis and protatitis). Cystitis involves the bladder and occurs when there is colonization and multiplication of the bacterial microbiota. Bladder infections are usually not complicated, but should be attacked in time and antibiotics administered, if necessary, it is always good when there is suspicion of bladder infection, perform a urinary culture as it is the gold standard test to know if There is a real infection and the type of microorganism present (bacteria or fungi) and how we can fight it. Good greetings in the post.
