Group A streptococcal cell walls inhibited phagocytosis of polystyrene latex particles by rat peritoneal macrophages in vitro. This inhibition was not accompanied by a measurable loss of cell viability. Group D streptococcal cell walls were relatively ineffective in altering phagocytosis. The effectiveness of group A variant streptococcal cell walls and peptidoglycan derived from group A cell walls was increased if cell wall preparations were added to macrophage cultures 12 h before, rather than simultaneously with, latex particles.
A组链球菌细胞壁在体外可抑制大鼠腹膜巨噬细胞对聚苯乙烯乳胶颗粒的吞噬作用。这种抑制作用并未伴随着细胞活力的可测量损失。D组链球菌细胞壁在改变吞噬作用方面相对无效。如果在巨噬细胞培养物中，在加入乳胶颗粒前12小时而非同时加入细胞壁制剂，则A组变异链球菌细胞壁和源自A组细胞壁的肽聚糖的效力会增强。
