<p>In infected animals, <i>Wolbachia</i> (in red) colonized many haemocytes (<b>A</b>, <b>B</b>) and the central area (*) as well as the cortex (**) of the haematopoietic organ (<b>C</b>), although groups of cells remained uncolonized (Arrowheads, <b>D</b>–<b>F</b>). The control uninfected animals presented only rare <i>Wolbachia</i>-like artefacts (haemocytes, <b>G–H</b>, haematopoietic organ, <b>I</b>). <b>A</b>–<b>C, G–H</b>: red: <i>Wolbachia</i>, green: Actin; blue: Nuclei. <b>A</b>, <b>B</b>, <b>G</b>, <b>H</b>: average intensity Z-projections. <b>B</b> and <b>H</b>: Close-ups. <b>D</b>–<b>F</b>: 3D analysis (ImageJ 3D viewer) of image <b>C</b>. <b>D</b>: tilted volume rendering of <i>Wolbachia</i> (red) and the nuclei (turquoise) in the central area extracted from the Z-stack. <b>E</b> and <b>F</b>: volume rendering of <i>Wolbachia</i> (grey-scale) from the whole haematopoietic organ. <b>E</b>: front view corresponding to image <b>C</b>, <b>F</b>: tilted view (180°).</p
