Figure 1: Co-infection increases disease prevalence.
From: Co-infection alters population dynamics of infectious disease

P. plantaginis epidemics in common garden P. lanceolata plots representing qualitative (a), quantitative (b), and susceptible (c) resistance strategies. Disease severity, measured as proportion of infected leaves, is shown at 17, 31, 53 and 76 days post inoculation (DPI) for the three pathogen treatments: strain 3 singly (green), strain 10 singly (blue) and co-infection of strains 3 and 10 (red). (d) Mean disease severity across P. lanceolata genotypes measured at the highest peak of epidemics (53 days after inoculation) comparing single infections (3=green and 10=blue) to co-infection treatment (red). Error bars are based on s.e.m.
