This selection of images are controls selected from a screen to find novel anti-infectives using the roundworm C.elegans . The animals were exposed to the pathogen Enterococcus faecalis and either untreated or treated with ampicillin, a known antibiotic against the pathogen. The untreated (negative control) worms display predominantly the "dead" pheotype: worms appear rod-like in shape and slightly uneven in texture. The treated (ampicillin, positive control) worms display predominantly the "live" phenotype: worms appear curved in shape and smooth in texture.
