Figure 5From: Molecular and biochemical characterization of urease and survival of Yersinia enterocolitica biovar 1A in acidic pH in vitroSurvival of Y. enterocolitica in vitro at different pH. Number of bacterial cells (log10CFU/ml) of Y. enterocolitica after incubation for 2 h at pH 2.5, 4.0 and 7.0 in the absence and presence (U) of 3.4 mM urea. The values are mean of three independent observations. The error bars indicate standard deviation.Back to article page
