Human monocytic ehrlichiae (Ehrlichia chaffeensis, Sapulpa strain) in host-cell membrane-limited parasitophorous vacuoles (morulae) of a DH82 cell (canine macrophage cell line). Ehrlichial reticulate cells (r) are limited by two membranes. The outer one -- the cell wall membrane -- is usually wavy (arrowheads). One Ehrlichia is dividing by binary fussion (arrow). Bar = 1 µm; magnification, x 18,000. (Courtesy of Vsevolod Popov, University of Texas Medical Branch at Galveston.)
