Table 2.6 displays the mean log 10 density <strong>of</strong> cells recovered from the 5 surfaces after 48 hour bi<strong>of</strong>ilm development with 1 Pseudomonas<br />

aeruginosa strain, 6 Salmonella enterica subspecies enterica serovar Agona strains, 3 Salmonella enterica subspecies enterica serovar<br />

Typhimurium strains and 2 Salmonella enterica subspecies enterica serovar Enteritidis strains. N denotes the number <strong>of</strong> replicate surfaces<br />

examined. The standard deviation <strong>of</strong> repeated measures (SD) was also calculated.<br />
