The result is a "polymicrobial infection of the vagina, in which various bacterial species participate, able to establish, in a synergistic way, conditions suitable for the development of others. There is thus an" alteration in the vaginal flora, with a decrease in Lactobacilli ( normally protective and responsible for maintaining the vaginal environment slightly acidic) and proliferation of pathogens.
The presence of bacterial vaginosis is signaled by itching, intimate burning and increased vaginal discharge (homogeneous white-greyish secretions, characterized by bad odor), but in about half of cases it is asymptomatic.
If neglected, bacterial vaginosis can cause gynecological complications, as well as favoring the transmission of venereal diseases through sexual intercourse.
most common among women.
The most important aspect is that this disease is characterized by a profound alteration of the ecosystem of the vagina, that is of the different populations of microorganisms that normally populate this part of the body and find a reciprocal condition of equilibrium (vaginal flora or microbiota).
The most important bacteria in the vaginal ecosystem are the Lactobacilli (also called Lactobacilli or Bacilli of Döderlein) and as happens in other districts, both the organism itself and these protective microorganisms benefit from this coexistence. The lactobacillary flora feeds on the glycogen present in vaginal secretions and synthesizes lactic acid, helping to keep the vaginal environment slightly acidic, at a pH of about 3.8-4.5. This acidity is particularly important for the body, as it hinders the growth of other pathogens that are harmful and capable of producing infections.
. However, in the presence of situations that can alter the vaginal ecosystem, the genitals can be vulnerable.
