Usefulness of polysaccharide and glycoprotein fractions of Trichomonas vaginalis in the serodiagnosis of Trichomonas infections

: It has been shown that glycoprotein and polysaccharide fractions obtained from T. vaginalis cells can be employed as antigens in serodiagnosis of trichomoniasis. This refers especially to the polysaccharide fraction because of its easy availability, solubility in aqueous solutions, high diagnostic specificity and sensitivity. It has been stated that the diagnostic value of polysaccharide antigen of T. vaginalis, in occult trichomoniasis in men particularly, is higher than the effect of the secretion examination by means of culture, even after the prostatic gland massage.
