自应用适当疗程的青霉素治疗 A 群β溶血性链球菌性咽峡炎以来,咽部链球菌常产生耐药性,致使各种治疗皆难奏效。反复应用青霉素,可选择性地增加产β乳糖酶的金黄色葡萄球菌、流感嗜血杆菌和拟杆菌的发生率,以致改变了口腔菌丛。这些产β乳糖酶的细菌很可能使青霉素失去活性,从而保护了 A群β溶血性链球菌。氏等对50例复发性扁桃体炎患儿实施手术,将其扁桃体核心部分进行需氧和厌氧细菌培养。结果每份标本平均分离出7.9个菌落(厌氧4.4,需氧3.5)。所有分离出的产β乳糖酶的细菌和
Since the application of the appropriate course of penicillin treatment of Group A beta hemolytic streptococcal angina, the pharyngeal streptococcus often produce resistance, resulting in a variety of treatments are difficult to work. The repeated application of penicillin can selectively increase the incidence of β-lactase-producing Staphylococcus aureus, Haemophilus influenzae and Bacteroides, thereby changing the oral flora. These beta-lactase-producing bacteria are likely to inactivate penicillin, thus protecting group A beta hemolytic streptococcus. And so on 50 cases of recurrent tonsillitis in children undergoing surgery, the core of its tonsil aerobic and anaerobic bacterial culture. Results An average of 7.9 colonies (anaerobic 4.4, aerobic 3.5) were isolated from each specimen. All isolates of beta lactase-producing bacteria and
