Fig. 1From: Identification of the crp gene in avian Pasteurella multocida and evaluation of the effects of crp deletion on its phenotype, virulence and immunogenicityDetection of maltose fermentation in S. Typhimurium. Three S. Typhimurium strains, S184 (Δasd) harboring the control plasmid pQK663, S411 (ΔasdΔcrp) harboring pQK663 and S411 (ΔasdΔcrp) harboring the complementary plasmid pQK163 (PM1157), were cultured on MacConkey maltose agar to observe the colors of the clonesBack to article page
