Serial images from a movie of a human neutrophil ingesting B. burgdorferi in vitro. Panel A shows engulfment of B. burgdorferi from one end by tube phagocytosis. Panel B shows the same neutrophil engulfing a spirochete initially attached at one end. The opposite end was subsequently captured, allowing the neutrophil to readily engulf the immobilized spirochete. From the unpublished archives of movies produced by Malawista (deceased) and de Boisfleury Chevance.
