Among these, Trichomonas vaginalis with over 140 million infected is ranked 4th, just after HBV with over 250 million infected, HPV with over 290 million and HSV ranked 1st with over 500 million infected. Despite the availability of treatment of this protozoan, it’s still prevalent both in the developing and developed countries, although chlamydial infections are on the rise, currently ranked as 5th by WHO. Trichomoniasis is twice as common as gonorrhea (~78 million), almost 4 times more common than HIV infections (~37 million) and 25 times more common than syphilis (~6 million). Trichomonas infection not only facilitates HIV acquisition due to epithelial damage, but also promotes HIV propagation. We aimed to re-evaluate our current knowledge on the lifecycle of Trichomonas vaginalis, including not only its multiplication, but also possible genetic exchange. Materials/methods: The study made use of two strains of Trichomonas vaginalis: reference strain ATCC-PRA-92 and the strain from the Chair of Microbiology of Jagiellonian University Medical College.
