  • Title: Isolation of inclusion bodies from vegetative Clostridium perfringens: partial purification of a 47 kDa inclusion protein.
    Author: Garcia-Alvarado JS, Labbé RG, Rodriguez MA.
    Journal: J Appl Bacteriol; 1992 Aug; 73(2):157-62. PubMed ID: 1328131.
    Abstract:
    A refractile inclusion body produced by vegetative cells of Clostridium perfringens at temperatures above 40 degrees C was isolated and partially characterized. The inclusion was composed of protein and could be solubilized by sodium dodecyl sulphate plus either dithiothreitol or beta-mercaptoethanol. The solubilized inclusion showed no antigenic relationship with Cl. perfringens enterotoxin. One major band with an apparent MW of 47 kDa was demonstrated after polyacrylamide gel electrophoresis of the solubilized inclusion. Both enterotoxin-positive and enterotoxin-negative strains produced the inclusion body. No effect on the morphology of several eucaryotic cell lines was observed when solubilized or intact inclusion was added to the cell cultures.
