As with the ivermectin resistance screen, we are able to find several mutants (blue) that show a different levels of recovery compared to the population of normal worms. This is a far more challenging screen and speaks to the power of our new imaging technology platform. https://images.squarespace-cdn.com/content/v1/5c34b48b9f8770ad9e8867d1/1551212645905-7KGIC3N5ID2MWGI8D670/pilot_screen_ivermectin.png Previous Work Figure 3: Identification of mutants resistant to the anthelmintic drug levamisole. Individual lines represent the thrashing motion of a population of worms in liquid over time. The behaviour of a normal population of worms (red) is to rapidly cease moving, while three populations of mutant worms (blue) show varying levels of resistance. https://images.squarespace-cdn.com/content/v1/5c34b48b9f8770ad9e8867d1/1551108668623-SHK7KOJ9SO9VVMUPO7KZ/drug_responses.png Previous Work Figure 1: A diversity of movement responses when worms are acutely treated with various drugs and physiological stresses.
