RESUMO
Las especies de Leuconostoc son patógenas oportunistas informadas en muy baja frecuencia, que se pueden encontrar en pacientes críticamente enfermos, inmunocomprometidos y con infecciones intra-hospitalarias. Generalmente, se asocian a bacteriemia por dispositivos intra-vasculares y al uso de nutrición parenteral total. Sin embargo, también se han descrito otras infecciones asociadas, dentro de las que se cuentan meningitis, osteomielitis, infección del torrente sanguíneo, de vías urinarias y peritonitis. En este artículo se describe una serie de pacientes con cáncer en quienes se identificó este microorganismo, las condiciones clínicas asociadas y se hace una revisión de la literatura.
The species of Leuconostoc are uncommon opportunistic pathogens, which can be isolated in critically ill patients, immunocompromised hosts and in nosocomial infections. They are mostly isolated in bacteremia associated to intravascular devices and to the use of total parenteral nutrition. Nevertheless, other infections due to Leuconostoc sp have been described among which, meningitis, bloodstream infections, urinary tract infections and peritonitis have been reported. In this article we describe a series of cancer patients with Leuconostoc sp infections and their associated clinical conditions, and a literature review is presented.

Among three strains of "Pycnosporus sanguineus", MIP 89007 produced more cinnabarin than MIP 95001 and MIP 95002. The antimicrobial activity of cinnabarin was tesred against 11 species of bacteria isolated from food. "Bacillus cereus" and "Leuconostoc plantarum" were the most sensitive to cinnabarin, being inhibited by 0.0625 mg/ml. "Klebsiella pneumonia" was the least sensitive (>4.0 mg/ml).
