The effect of incubation temperatures of 41, 37, and 4 degrees C on phagocytosis was investigated using human neutrophils and [3H]thymidine-labeled staphylococci. Depressed phagocytosis was observed at 41 and 4 degrees C. At 41 degrees C diminished staphylococcal uptake resulted from decreased attachment of bacteria to leukocytes; the inhibitory effect at 4 degrees C was secondary both to decreased opsonization and to reduced attachment to leukocytes. In contrast to the findings with normal serum, opsonization with heat-inactivated serum appeared to be relatively intact at 4 degrees C. By incubating samples in lysostaphin, it was determined that the process of bacterial ingestion as well as that of attachment was adversely affected by incubation temperatures of 41 and 4 degrees C.
利用人中性粒细胞和[3H]胸腺嘧啶核苷标记的葡萄球菌,研究了41℃、37℃和4℃的孵育温度对吞噬作用的影响。在41℃和4℃观察到吞噬作用受到抑制。在41℃时,葡萄球菌摄取减少是由于细菌与白细胞的附着减少所致;在4℃时的抑制作用继发于调理作用降低和与白细胞的附着减少。与正常血清的结果相反,用热灭活血清进行调理在4℃时似乎相对完整。通过在溶葡萄球菌素中孵育样品,确定41℃和4℃的孵育温度对细菌摄取过程以及附着过程均产生不利影响。
