ABSTRACT
Leuconostoc is a gram-positive cocci, quite ubiquitous in nature. It is used in wine industry, and for aroma and texture of dairy products. Occasionally it has been isolated from humans in cases of bacteremia, catheter associated infections, sepsis, meningitis, pneumonia, UTI, osteomyelitis and hepatic dysfunction. Short bowel syndrome, patients with CVC and patients with gastrostomy undergoing enteral feeding, are described amongst the factors associated with this infection. The isolation of a gram-positive cocci, that does not hydrolyze arginine and that is resistant to vancomycin leads to this diagnostic possibility. Antibiotic treatment: penicillin or ampicillin.

Leuconostoc es una cocácea grampositiva parecida a los Streptococcus, que se encuentra ampliamente distribuida en la naturaleza; es usada en la industria de vinos, productos lácteos y quesos para la producción de aromas y texturas. Leuconostoc causa ocasionalmente infecciones en humanos, puede producir bacteriemia, infección asociada a catéter, síndrome séptico, meningitis, neumonía, infección del tracto urinario, osteomielitis y compromiso hepático, entre otros. Se describen como factores de riesgo para una infección por este agente: el síndrome de intestino corto, uso de catéter venoso central y la alimentación enteral por gastrostomía. Orientan a la presencia de este agente el aislamiento de una cocácea grampositiva, catalasa negativa, PYR y LAP negativas, resistente a vancomicina. El tratamiento de elección es penicilina o ampicilina.
