Abstract

The bacteriostatic and bactericidal effects of chloramphenicol, ampicillin, tetracycline, and sulfisoxazole were compared against several potential meningeal pathogens. Chloramphenicol is bactericidal at clinically achievable concentrations against Haemophilus influenzae, Streptococcus pneumoniae, and Neisseria meningitidis. It is bacteriostatic against gram-negative bacilli of the family Enterobacteriaceae and against Staphylococcus aureus. Chloramphenicol has proven highly efficacious in the treatment of bacterial meningitis caused by those organisms against which it is bactericidal at low concentrations. Because leukocytic phagocytosis in the subarachnoid space is inefficient, we propose that bactericidal activity in cerebrospinal fluid is important for optimal therapy of bacterial meningitis. Chloramphenicol does not provide such activity in meningitis caused by enteric gram-negative bacilli.

摘要

比较了氯霉素、氨苄西林、四环素和磺胺异恶唑对几种潜在脑膜病原体的抑菌和杀菌作用。氯霉素在临床可达到的浓度下对流感嗜血杆菌、肺炎链球菌和脑膜炎奈瑟菌具有杀菌作用。它对肠杆菌科革兰氏阴性杆菌和金黄色葡萄球菌具有抑菌作用。氯霉素已被证明在治疗由低浓度时具有杀菌作用的那些病原体引起的细菌性脑膜炎方面非常有效。由于蛛网膜下腔中的白细胞吞噬作用效率低下,我们认为脑脊液中的杀菌活性对于细菌性脑膜炎的最佳治疗很重要。氯霉素在由肠道革兰氏阴性杆菌引起的脑膜炎中不具有这种活性。
