Opportunistic anaerobic bacteria
These bacteria are generally anaerobic (multiply without oxygen), and are associated with Bacterial Vaginosis (BV) if found at relatively high levels (over 1 million total genomic copies / ml). A significant level of these microbes represents a dysbiosis (imbalance) in the vaginal microbiome which can have wider health consequences. Some of these microbes detected at very low levels, may be harmless and require no action. BV only presents with symptoms in about 50% of women.1
Symptoms include a watery, white or grey discharge and a strong fish odour. Lifestyle factors can increase the chances of developing BV. Factors such as such as age, oestrogen status, diet and lifestyle and sexual partners may need to be addressed alongside medical treatment in cases of BV. Medical treatment is especially implicated in cases of fertility.
