Fig. 3From: Influence of pCP1NetB ancillary genes on the virulence of Clostridium perfringens poultry necrotic enteritis strain CP1RT-PCR analyses for netB expression by CP1, CP1ΔpCP1netB and complementing strain CP1ΔpCP1netB(netB +). M, Low Range DNA Ladder; Lanes 1, 3, 5 (with +) were from samples receiving reverse transcriptase (RT), while lanes 2, 4, 6 (with −) lacked reverse transcriptase to show the absence of DNA contaminationBack to article page
