VISITING SPEAKER: Variable parasites - variable defences?
A world recognised specialist in the field of ecology and evolution of host-parasite interactions, Paulís research interests focus on the coevolution and ecology of host-parasite interactions.
As head of the Experimental Ecology research group at ETH, his pioneering works on host-parasite interactions paved the way for innovative research worldwide.
The trypanosome Crithidia bombi infects several species of Bombus (bumblebees); here, we focus on B. terrestris. The parasite is spread by contacts on flowers and evidence shows that the infecting populations in the hosts are very prevalent and highly variable. At the same time, the presumably relevant genetic complements of the hosts are highly conserved. One alternative defence strategy is by variable gene expression and the synergistic actions of effector molecules. The concept and evidence for such a process are discussed.
