链球菌感染所致的咽炎、猩红热、脓皮病、丹毒等是常见病。虽然近20年来由于抗菌药物的广泛应用,这些疾病的发病率和死亡率已大大降低,但与链球菌感染密切相关的风湿热和急性肾炎还屡有发生。因此,对链球菌感染的防治仍然是一个重要的研究课题。 Streptococcus infection caused by pharyngitis, scarlet fever, pyoderma, erysipelas is a common disease. Although the incidence and mortality of these diseases have been greatly reduced due to the widespread use of antimicrobial agents in the past 20 years, the frequent occurrence of rheumatic fever and acute nephritis, which are closely related to streptococcal infection, has also occurred. Therefore, the prevention and treatment of streptococcal infection is still an important research topic.
