An elementary body of the intracellular symbiont Protochlamydia amoebophila, infecting its Acanthamoeba host, was captured by scanning electron microscopy. Sixt et al. report on the metabolism and the effect of nutrient availability on infectivity of this extracellular stage that has long been considered metabolically inert. See Sixt et al.
