Fig. 8From: Tick transmission of Borrelia burgdorferi to the murine host is not influenced by environmentally acquired midgut microbiotaTransmission electron microscopy (TEM) of tick midguts shows intracellular Borrelia burgdorferi near the basal lamina of the midgut epithelial lining. B. burgdorferi-infected ticks fed on pathogen-free mice for 48 h were dissected to obtain tick midguts, processed for TEM analysis and visualized. Panels I, II, and III are representative of approximately 10 midguts at 48 h of feeding showing B. burgdorferi near the basal lamina, but no points of egress observed.
