  Title The red pigment prodigiosin is not an essential virulence factor in entomopathogenic Serratia marcescens Type Journal Article
  Year 2016 Publication Journal of Invertebrate Pathology Abbreviated Journal J Invertebr Pathol  
  Volume 136 Issue Pages 92-94  
  Keywords Prodigiosin; Serratia marcescens; Silkworm; Virulence  
  Abstract Although pigments produced by pathogenic microbes are generally hypothesized as essential virulence factors, the role of red pigment prodigiosin in the pathogenesis of entomopathogenic Serratia marcescens is not clear. In this study, we analyzed the pathogenicity of different pigmented S. marcescens strains and their non-pigmented mutants in silkworms. Each pigmented strain and the corresponding non-pigmented mutants showed very similar LD50 value (statistically no difference), but caused very different symptom (color of the dead larva). Our results clearly indicated that the red pigment prodigiosin is not an essential virulence factor in entomopathogenic S. marcescens.
