Microarray detection limit profile using different concentrations of Salmonella cells spiked into a faecal sample. Microarray detection limit profile for the Salmonella genus probe using serial dilutions of S. enterica serovar Typhimurium cells spiked into a human faecal sample. The standard error is represented by error bars. The P values are the degree of significance between the intensity recorded from a particular serial dilution and the intensity value obtained from the control sample with no spike.
