Technical note: Preservation of Trichomonas vaginalis viability in urine for laboratorial diagnosis by the wet mount examination.

This study compared preservative solutions at different temperatures aiming to improve the wet mount for trichomoniasis diagnosis. The glucose-saline pH6.0 solution preserved the trophozoites up to 6h. The urine samples preservation is crucial for diagnosis and we suggest this solution as part of the clinical laboratorial routine.
