Caption:
This photograph depicts three test tubes, each containing a motility medium with triphenyl tetrazolium chloride (TTC), as a growth indicator. The far left tube was inoculated with an ATCC control strain of non-motile Staphylococcus bacteria, and incubated for a 24 hour time period. The middle tube was inoculated with an ATCC control strain for non-pathogenic, motile, Escherichia coli bacteria, and also incubated for a 24 hour time period. The far right tube was also inoculated with the ATCC control strain for non-pathogenic, motile, Escherichia coli bacteria, but allowed to grow for a 5-day time period, which allowed for the bacterial swarm, in order to represent what would happen had Salmonella enterica serovar Typhimurium bacteria been used in place of the E. col.
