Histoire de mouches et de champignons, mêlant infection, zombification et nécrophilie.

Pour assurer leur dissémination, certains parasites et agents pathogènes ont la capacité de manipuler le comportement de l’hôte qu’ils infectent. D’autres agents infectieux jouent, eux, sur l’utilisation de signaux trompeurs d’accouplement pour attirer leurs victimes. Assez rare sont les agents pathogènes à faire les deux.

Chronique diffusée le 27 octobre 2022. L’ensemble des chroniques est accessible sur une playlist dédiée.
