Enterococcus faecalis may cause vaginitis. Enterococcus faecalis belongs to the genus Streptococcus and is often found in the digestive, respiratory, and reproductive tracts of humans. The vagina contains a variety of bacteria, including anaerobes and Gardnerella, etc. Enterococcus faecalis and a variety of bacteria are in balance and interact with each other to maintain the bacterial balance in the vagina. However, if you use antibiotic drugs for a long time, over-wash your vagina or suffer from some immune disorders, it may lead to changes in the flora in the vagina, so that the vaginal lactobacillus bacteria will decrease and the pH of the vagina will increase, and other microorganisms in the vagina will reproduce in abundance, including Enterococcus faecalis, which will lead to vaginitis, which is more commonly known as bacterial vaginosis or mixed type of vaginitis. If you suspect vaginitis, you should communicate with your doctor in a timely manner to make a comprehensive diagnosis and standardize treatment based on clinical symptoms and examination results.
