Fig. 4From: Influence of pCP1NetB ancillary genes on the virulence of Clostridium perfringens poultry necrotic enteritis strain CP1LMH cell cytotoxicity assay. Culture supernatants were isolated from CP1, CP1ΔpCP1netB and complementing strain CP1ΔpCP1netB(netB +). The experiment was repeated three times, and average results are shown. Error bars depict standard deviation (SD). The amount of cytotoxicity induced by NetB in each cell supernatant is expressed as a percentageBack to article page
