全苏抗菌素研究所所获得的红霉素的抗菌素比青霉素广,对球菌族的细菌以及白喉桿菌有显著的抗菌作用。这个抗菌素的优点,是在于它具有抑制对青霉秦有抗药性的细菌的能力。作者在体外的试验中,进行比较研究,研究从猩红热病人身上新分离出来的溶血性鏈球菌和葡萄球菌菌株,对红霉素,青霉素和四环素的敏感性,以及在小白鼠实验性的鏈球菌和 All-Soviet antibiotic Institute of erythromycin obtained antibacterial wide than penicillin, bacteria of the coccus and diphtheria bacilli have significant antibacterial effect. The advantage of this antibiotic is that it has the ability to inhibit bacteria resistant to penicillin. In an in vitro study, the authors conducted a comparative study to study the susceptibility of hemolytic streptococci and staphylococci newly isolated from patients with scarlet fever to erythromycin, penicillin, and tetracycline, as well as experimental streptococcus in mice with
