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.

Biologists at Vanderbilt University have discovered DNA of the black widow spider toxin in the genome of a virus that attacks Wolbachia, a type of symbiotic...

The inoculation of viruses into mosquito bite sites is an important and common stage of arbovirus infections. Dr. McKimmie and his colleagues show that inflammation at bite sites aids viral replication and dissemination in vivo, resulting in more severe infection. These findings define additional targets for post-exposure prophylactic intervention. Image credit: Marieke Pingen et al.
