Cumulative shedding curves of E. coli strain M175 containing mcr-1 by individual ring-billed gulls. Half of the six inoculated individuals shed similar cumulative amounts in their feces while the M175 strain was not detected in the feces of the other half. Dashed red line is the curve of the contact control bird that became colonized with mcr-1 positive E. coli while housed with inoculated birds.
