Infection dynamics of Dd2 and HB3. A) Dd2 (brown circles) competitively suppresses HB3 (black squares) when parasites are grown together in culture. B) No difference is detected between Dd2 grown in single culture (orange circles) and in mixed culture with HB3 (brown circles). C) HB3 reaches higher densities when grown in single culture (grey squares) than in mixed culture with Dd2 (black squares). Points are means of three replicates, error bars represent standard deviation.
