Temperature-dependent changes to host–parasite interactions alter the thermal performance of a bacterial host

摘要

Thermal performance of phage and bacteria. a Phage replication increased with temperature up to an optimum before declining rapidly to a negative replication rate at 30 °C. b Bacteria growth showed unimodal responses to temperature in the presence (black) and absence of phage (blue). However, phage changed the shape of the thermal response. Points represent an independent replicate at each temperature. Solid lines represent the mean prediction and shaded bands represent the 95% credible interval of predictions. In a the dashed line represents 0 growth, below which phage abundance decreased. In b, the dashed line represents the CTmax of the phage, beyond which phage abundance decreased
