Fig. 2

Cluster of Neorickettsia in P. elegans (HPF/FS). a Loose, morula-like cluster of endobacteria (arrows) surrounded by a double membrane (arrowheads) in proximity of the gut. Note the rough endoplasmatic reticulum in the trematode’s cytoplasm (asterisks). b Similar cluster of endobacteria (arrows) as in a, but without vacuole membranes. c Three endobacteria (arrow) in the vicinity of an accumulation of electron-dense mitochondria in the glycogen rich parenchyma. d Group of non-dividing endobacteria (arrows) in the tegument. Note the tubular or vesicular structures (arrowheads) between the endobacteria. e Endobacteria (arrow) in proximity of polymorphic vesicle structures (arrowhead) and rough endoplasmatic reticulum (asterisk). f Endobacterium (arrow) in binary fission. Note the different layers of membranes (arrowhead). Abbreviation: m, mitochondrion. Scale-bars: 500 nm
