Trichomonas is a parasitic sexually transmitted infection that usually infects females and gives rise to symptoms such as vaginal discharge. It is also implicated in higher rate of premature deliveries and increases susceptibility to HIV infection. Many women are infected with TV without knowing it.
A recent study has shown that women who suffer with bacterial vaginoses are at increased risk of acquiring TV. They also realised that there were unique bacterial communities that made women more susceptible to TV. These contained high concentrations of bacteria called Mycoplasmas. Women who had this bacteria and TV had worse discharge and inflammation. They commented that this group might be even more at risk of catching HIV. The interesting thing is that it seems that the TV causes these changes in vaginal flora and might actually cultivate the Mycoplasmas to make the environment more beneficial to itself.
