Comparison of theoretical predictions and real hybridization patterns for the Salmonella array and previously typed strains (CDC, DSMZ).

Hendriksen, DTU Food, Denmark.Calculation of similarities was carried out by comparing predictions to measured signals for all 255 probes. Signals with intensities higher than 0.3, were considered positive and set as “1”. Signals lower than 0.3 were regarded negative and set as “0”. The number of probes which differ was summarized and the percentage was calculated.
