Figure 2. Bacterial Deprivation and Fluoranthene Treatment Reduce Pharyngeal Pumping.

Pharyngeal pump rates of N2 and eat-2(ad1116) animals after 24 hours treatment with DMSO or FLA under control-fed (Fed) or bacterially deprived (BD) conditions. Pharyngeal pumping was reduced in both FLA treated and BD populations. *denotes p>0.0001 compared to DMSO treated samples. Rates are recorded as pumps per minute. Summary data and statistics are shown in Table 1 .
