FIG 4 .

Double-parameter variations indicate that protection from Mucor circinelloides is dependent on maximum phagocyte number at the site of infection (varying K_M and an additional parameter as indicated by the y label) as applied to the mathematical model using “susceptible” zebrafish parameters (K_N = 12), and impact of their variation on time taken to reach H* (indicating death from mucormycosis). The dashed line marks 120 h: where the plane lies above the dashed white line, zebrafish are deemed to survive for the corresponding parameter values.
