<s>[INST] Are all microorganisms in urine culture the same? Are there bad and good bacteria? [/INST] By definition, there are no "bad" or "good" bacteria, but microorganisms that coexist with the human body, with some even helping it to carry out some of its functions. Other microorganisms, on the other hand, cause diseases. Establishing whether a microorganism has pathogenic potential is not easy and is done only in the field of research. It is the role of health professionals to establish whether a microorganism in the urine is causing disease or not, with information about the symptoms provided by the patient.
