An environmental isolate of Salmonella Enteritidis (SE), grown to the logarithmic phase, rapidly lost culturability by the addition of 3 mM H2O2 to cultures grown in Luria-Bertani (LB) medium; however, some H2O2-treated bacteria regained their culturability in M9 minimal medium, if sodium pyruvate was present at at least 0.3 mM. In addition, most pyruvate(More)
Synthetic antimicrobial 9-mer peptides were designed from the amino acid sequence of an active site of insect defensin to increase the number of positively charged amino acid residues. These peptides, RLRLRIGRR-NH2, RLLLRIGRR-NH2 and RLYLRIGRR-NH2, showed strong antimicrobial activity against bacteria and fungus. These peptides showed no growth inhibition(More)

Activated macrophage phenotypes were influenced by the culture medium; a murine macrophage-like cell line, J774.1/JA-4, expresses different activated-macrophage phenotypes induced by lipopolysaccharide (LPS) and/or interferon-γ (IFN-γ) when the cells are incubated in either Ham's F-12 medium (F-12) or Dulbecco's modified Eagle medium (DMEM). Among these(More)
