Could i be colonized with group b strep in my uterus without having a serious infection? not pregnant.

Not abnormal: Group B streptococcus is a normal bacteria in the female genital tract. It can cause serious problems in newborns exposed to it during vaginal delivery, and therefore testing is routine in pregnancy. However, in other situations testing usually is not recommended and nothing need be done if GBS is found. It isn't likely to cause any sort of problem.

Common germ: An estimated 30-40% of women carry GBS intermittently through life in their genital tract.It is a benign gut germ and occasionally causes a UTI in women. It becomes an issue if a baby acquires the germ from mom before or during delivery and gets very sick from it. Except for that setting, it is just a common germ you ignore.
