House flies excreted viable GFP-<i>P. aeruginosa</i> during multiple time-intervals after ingestion.

Flies were fed a mean of 2.02×105 (SD = 6.30×104) CFU of GFP-P. aeruginosa. Incidence of excretion (%) is for n = 12 flies per time interval, and mean CFU is calculated only from flies that excreted viable, countable bacteria.
