The web of interactions and magnitude of effects between microparasite species in the Kielder field voles. Positive associations (odds ratio [OR]>1) are in red, negative associations (OR<1) in blue, with intensity of line reflecting the magnitude of an effect. 95% confidence intervals of OR shown in parentheses. Infection history associated with effect also noted: N = negative, P = positive. NP therefore signifies no infection at t-1 and infection at t0. Thus, for example, individuals with chronic B. microti infections are ∼2 times more likely to be infected with A. phagocytophilum (OR = 2·34) while those with new B. microti infection are ∼5 times more likely to be infected (OR = 5·43).
