Type of Preparation: SurePath/ LBP Magnification: High Clinical History: Not provided Interpretation: NILM: Trichomonas vaginalis and Leptothrix Cytomorphologic Criteria: Leptothrix are slender, long bacteria that may be seen in association with Trichomonas. Explanatory Notes: The finding of Trichomonas and leptothrix together has been referred to as "spaghetti and meatballs" The leptothrix should be distinguishable from Doderlein bacilli, that are normally seen. When leptothrix are seen, one should search for the possible presence of trichomonads. In liquid based preparations, the leptothrix organisms may tend to clump (as seen in this image) as opposed to conventional smears.
