Subboiling Moist Heat Favors the Selection of Enteric Pathogen Clostridium difficile PCR Ribotype 078 Spores in Food

Figure 4

Predicted survival probabilities for three C. difficile genotypes show increased survival odds for PCR 078 as the number of survivor spores tested decreases as heat lethality increases. Raw data is from 1 : 1 : 1 strain mixture from Figure 3(c), plotted against the number of surviving colonies. The sum of probabilities at each value on the -axis equals 1, up to 3 independent replicates for each -axis value. Distinct superscripts indicate significant differences, multivariable multinomial logistic adjusted . Inset, plot of estimated smoothed probabilities of survival for the predicted data depicted in dot-line plot, without controlling for temperature.
