在体内某些菌株能产生杀死同种或种类相近菌株的物质,它可引起细菌之间的干扰现象。这些杀菌物质能被敏感细胞表面的特异受体所吸收,从化学角度看,它们是蛋白质,称其为细菌素(Bacteriocin)。已记载有很多革兰氏阳性和阴性细菌中含有细菌素。根据Bergey的意见,以往认为肠杆菌科雷极氏变形杆菌无细菌素。在慕尼黑的一些医院里这类菌株常引起尿道感染。作者在有计划地研究中检获一种雷极氏变形杆菌的细菌素(rettgerocin),它对雷极氏变形杆菌若干株、沙门氏菌株均有杀菌活力。为研究细菌素和抗菌素间的可能联合作
Some strains in the body produce substances that kill similar strains of the same species or species, which can cause interference between bacteria. These bactericidal substances can be absorbed by specific receptors on the surface of sensitive cells, which, from a chemical point of view, are proteins called bacteriocins. A number of Gram-positive and -negative bacteria have been documented to contain bacteriocins. According to Bergey’s opinion, past enterobacteria Klebsiella Proteus bacteria-free bacteriocins. In some hospitals in Munich, such strains often cause urinary tract infections. In a systematic study, the authors seized a rettgerocin from Proteus mirabilis that has bactericidal activity against several strains of Proteus mirabilis and Salmonella. To study possible combinations of bacteriocins and antibiotics
