Pathogen within-host dynamics and disease outcome: what can we learn from insect studies?

D Duneau, JB Ferdy - Current Opinion in Insect Science, 2022 - Elsevier
Parasite proliferations within/on the host form the basis of the outcome of all infectious
diseases. However, within-host dynamics are difficult to study in vertebrates, as it requires …

Drosophila immune priming to Enterococcus faecalis relies on immune tolerance rather than resistance
