Fig. 5From: Influence of pCP1NetB ancillary genes on the virulence of Clostridium perfringens poultry necrotic enteritis strain CP1Lesion scores from chickens infected with different C. perfringens CP1 derivatives. The lesion scores of individual 18-day-old broiler chickens challenged with different C. perfringens strains are shown. Control group and CP1 group consisted of 13 birds; CP1ΔpCP1netB and complementing strain CP1ΔpCP1netB(netB +) groups consisted of 14 birds. The solid horizontal bars represent the average lesion score in each groupBack to article page
