Due to an unfortunate turn of events, an incorrect version of Fig. 4 has been used in the above-mentioned publication. The correct image and its caption is published on the following page and should be treated as definitive by the reader.

Fig. 4.

Fourth to fifth day of Rickettsia helvetica-infected Vero cells. a Morphology of R. helvetica in partly decomposed host cells. Note the leaflets (arrow heads) and inner plasma membrane enclosing the periplasmatic space (ps). Fibrillate nucleic acid is clearly visible (long arrows) ×120,000. Bar 150 nm. b Anti-rickettsia antibodies with gold particles (gp) (15 nm) on Lowicryl-embedded cells. Leaflets and plasma membrane (arrows heads) and fibrillar nucleic acid (long arrows) are visible. The immunoreaction is mainly located along the membrane/leaflet part of the rickettsia but sparsely scattered all over the organism ×120,000. Bar 150 nm
