Figure 1. OP50 E. coli-fed nematodes are generally healthy while pathogen-fed worms demonstrate a decrease in overall health.

Figure 1

(A), (B), and (C) The average pumping rate in a 20 second interval for nematodes fed OP50 or a pathogen. (A) All pumping rates are similar in N2 and mutant animals. (B) The average pumping rate for nematodes fed P. aeruginosa is decreased when compared to N2 animals fed OP50. Worms with a pmk-1(km25) background exhibit the largest decrease in pumping rate. (C) The average pumping rate for nematodes fed S. aureus is decreased when compared to N2 animals fed OP50. Double mutant ogt-1; pmk-1 animals exhibit the largest decrease in pumping rate. Statistics are available in Table S2 and error bars represent standard deviation. All experiments were performed at 18°C. n = 10–25 animals.
