肺泡腔中嗜中性粒细胞吞噬了革兰阳性菌

肺泡腔中嗜中性粒细胞吞噬了革兰阳性菌

图示:革兰氏染色显示大量渗出到肺泡腔的嗜中性粒细胞吞噬了革兰阳性菌。调理素(如IgG和补体C3b)能促进嗜中性粒细胞粘附破坏病原如细菌,从而使嗜中性粒细胞能有效的吞噬病原。

This tissue gram stain of an acute pneumonia demonstrates gram positive cocci that have been eaten by the numerous PMN's exuded into the alveolar space. Opsonins such as IgG and C3b facilitate the attachment of PMN's to offending agents such as bacteria so that the PMN's can phagocytose them.
