Background
Microbiology
- Gram-positive coccus similar to Streptococcus
- Catalase negative, alpha-hemolytic or gamma-hemolytic, and Lancefield group D
- Includes six species, of which Leuconostoc mesenteroides and Leuconostoc paramesenteroides are more common
Epidemiology
- Found on food, including vegetables, dairy, and processed meats, as well as vaginal and gastrointestinal tract
Clinical Manifestations
- Can colonize mucosal surfaces as well as gastrostomy and tracheostomy sites
