Definition / general
- Leptothrix are long, slender, gram negative, non spore forming anaerobic organisms that may be seen in association with Trichomonas
- Also known as Leptotrichia or Leptotrichia buccalis
- Oral and vaginal cavities
- Nonpathogenic by themselves but 75% - 80% of cases have associated Trichomonas vaginalis (Bibbo: Comprehensive Cytopathology, 4th Edition, pg.103 - 4)
- Other associated infective organisms include Candida and Garderella vaginalis
- No treatment unless associated with a pathogen
- Long, thin, segmented, filamentous structures
- Usually nonbranching but occasionally branching may be observed
- May form loops more frequently in conventional smears
- May show acute inflammatory changes
- Tend to form clumps in liquid based cytology preparations (LBC), as opposed to conventional smears
- Trichomonas and Leptothrix together have been referred to as "spaghetti and meatballs"
- Lactobacillus: shorter than Leptothrix and do not form loops
