The ash tree (Fraxinus excelsior) is one of Europe’s largest native deciduous trees. Image credit: Matthieu Sontag / CC-BY-SA. Ash trees (genus Fraxinus) are widespread throughout the Northern Hemisphere, but are being devastated in Europe by the fungus Hymenoscyphus fraxineus, causing ash dieback. The disease is aggressive, spreads quickly through the population, and has no cure, other than individual natural tolerance to the infection. It is spread...

Electron microphotograph shows two Wolbachia cells that have infected a Nasonia wasp. The one to the left is infected with the WO phage, pointed out by the black arrowheads. The one to the right is uninfected. The large dark patch is bacteria DNA that has been degraded by the phage. The image also shows the multiple wasp membranes wrapped around the Wolbachia that the phage must penetrate both to enter and escape from the bacteria.
