The bactericidal properties of human cell-free lymph have been investigated. Gram-negative and gram-positive bacteria are susceptible to the killing action of lymph fluid. The colony-forming ability of Escherichia coli and Bacillus subtilis was reduced by 3 logs after 20 min of incubation with 10% (vol/vol) lymph. Salmonella and Listeria were less susceptible to killing. The presence of multiple killing factors in lymph showing different specificities for different bacterial cells was demonstrated.
已对人体无细胞淋巴液的杀菌特性进行了研究。革兰氏阴性菌和革兰氏阳性菌均易受淋巴液的杀伤作用影响。用10%(体积/体积)的淋巴液孵育20分钟后,大肠杆菌和枯草芽孢杆菌的集落形成能力降低了3个对数级。沙门氏菌和李斯特菌对杀伤作用的敏感性较低。研究证明,淋巴液中存在多种杀伤因子,这些因子对不同细菌细胞具有不同的特异性。
