[Microbiological and clinical studies of vancomycin resistant Leuconostoc spp. and Pediococcus spp. isolated from septicemia patients]

We described three septicemia cases in which blood cultures yielded gram-positive cocci identified as Leuconostoc spp. and Pediococcus spp. Patients were three male adults aged 63 to 71 years with severe underlying diseases, pancreatic cancer, esophageal cancer and diabetes mellitus with chronic renal failure. They had fever and chills at the onsets of septicemia with acute obstructive suppurative cholangitis, acute pneumonia, and infection complicated with invasion sites of esophageal cancer contagious to bronchus and subcutaneous tissue. Blood cultures yielded catalase and oxidase negative highly vancomycin-resistant (MIC: 1024 micrograms/ml
