ABSTRACT

Trichomonas vaginalis (T. vaginalis) is a flagellated protozoan commonly causing sexually transmitted disease. T. vaginalis infections are treated with a 5-nitroimidazole derivate. However, drug resistance has been known to occur for a long time and new alternatives are under investigation. Arbutus unedo is a wild plant mainly growing in maquis and rocky places of the seaboard in Southern Europe. In our study, ethanolic, water, hexane and ethyl acetate extracts of Arbutus unedo leaves were tested in vitro against T.vaginalis trophozoites and the ethyl acetate extract of Arbutus unedo leaves was found to be effective (Growth inhibition rate (GI): 100%, at the concentration of 500 μg/ml). It may be a promising anti-trichomonacidal agent in the future and further experiments are needed.
