title: Trichomonas vaginalis--identification by rapid BPT-Drăgan staining.
abstract: The blue-polychrome-tannin rapid staining (BPT-Drăgan, 1968) applied on fresh and dried vaginal smears makes possible the identification of different forms of Trichomonas vaginalis (TV) parasite. The nucleus is coloured in blue-violet and the cytoplasm in various degrees of blue-green, violet or bichromatical, with blue and violet zones at the cell periphery. In the cytoplasm, the staining allows the identification of many granules and vacuoles. All the stainable substrates have an acid character and represent morphohistochemical aspects which reflect the parasite metabolism in different functional and evolutive stages. Our results allow the recommendation of the method in the screening actions of the TV identifications.
