Vaginal secretions can usually be cultured for E. coli because E. coli is part of the normal vaginal flora. E. coli is the normal flora in the human intestinal tract, while a small amount of E. coli is also found in the female vagina. More than 20 types of microorganisms can be isolated from a normal woman’s vagina, which are predominantly bacteria, mostly Lactobacillus, but also a small amount of E. coli, and do not cause disease. When the local microenvironment of the female reproductive tract changes due to certain reasons, E. coli may become the dominant bacteria and lead to the occurrence of urinary tract infections, which are caused by most of the pathogens of urinary tract infections. If the genital tract secretions cultured E. coli, and there are obvious clinical symptoms, you should promptly go to the hospital, improve the relevant examination to clarify the cause of the disease, under the guidance of the doctor symptomatic treatment.
