These images show macrophages infected with anthrax. The fluorescent green areas indicate the presence of nitric oxide (NO). In the top two panels, the anthrax can produce NO. At top left, an image taken two hours after infection shows that NO is present. At 18 hours, top right, more NO is present, produced by the macrophages. In the bottom two panels, the anthrax infecting the macrophages is unable to produce NO. At bottom left, after two hours, almost no NO is present, but it is present (produced by the macrophages) at 18 hours, bottom right. Image / Stephen Lippard |
