人們早已发現某些微生物对抗菌素能产生耐葯性,随着抗菌素的广泛应用,各种致病菌的耐葯情况有日益严重的趋势。青霉素本是一个較为理想的化学治疗剂,在临床上一直占据相当重要的地位。但耐葯金黃色葡萄球菌的不断增加,却大大降低了該菌对青霉素的敏感度,給临床治疗工作造成了严重困难。 It has long been discovered that some microorganisms can produce antibiotic resistance to antibiotics. With the extensive application of antibiotics, the resistance of various pathogenic bacteria is becoming more and more serious. Penicillin this is a more ideal chemotherapeutic agent, has been occupying a very important position clinically. However, the continuous increase of resistant Staphylococcus aureus has greatly reduced the sensitivity of the bacterium to penicillin, which has caused serious difficulties in clinical treatment.
