Fig. 5From: Interaction of Borrelia burgdorferi with Peripheral Blood Fibrocytes, Antigen-Presenting Cells with the Potential for Connective Tissue Targeting Interaction of B. burgdorferi with human peripheral blood mononuclear cells. Human polymorphonuclear leukocytes and isolated peripheral blood fibrocytes were incubated with B. burgdorferi as described in Figures 2 and 3. (A) Coiling phagocytosis of peripheral blood mononuclear cells incubated with B. burgdorferi JD1 for 2 hr. Two spirochetes (asterisks) are enveloped by a coiling pseudopodial cell extension. Bar = 500 nm. (B) Mononuclear cell with large phagocytic vacuoles (asterisks) containing spirochetes. Bar = 2 µm.Back to article page
