Light microscopic and ultrastructural evidence of in vivo phagocytosis of Helicobacter pylori by neutrophils.

abstract：:We have carried out a systematic ultrastructural study of the bacilli, the cell-mediated response in the host, and the dermal microvasculature in lepromatous (LL), borderline lepromatous (BL), and borderline tuberculoid (BT) types of active leprosy (eight cases). In the types of least resistance (LL and BL), macrophag...
