Infected & Uninfected Wolbachia Cells (IMAGE) Vanderbilt University Caption This electron microphotograph shows two Wolbachia cells that have infected a Nasonia wasp. The top one is infected with the WO phage, pointed out by the black arrowheads. The bottom one 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.
