    • A composition for removal of biofilm in the airway passage is useful for the treatment of infections such as pneumonia cause by Mycoplasma pneumoniae. In general, the composition comprises: (1) a quantity of at least one enzyme that catalyzes the hydrolysis of a bond that connects two monosaccharides in a polysaccharide or that connects a monosaccharide with a protein molecule in a glycoprotein sufficient to break down biofilm in the airway; and (2) a pharmaceutically acceptable carrier suitable for administration into the airway. The composition can further include ingredients such as a steroid, lysozyme, lactoferrin, or a peroxidase; if a peroxidase is included, the composition can further include an oxidase to generate peroxide as well as a substrate for the oxidase. The composition can be used in methods for treatment of an infection based on the ability of the composition to dissolve biofilm in the airway.
    • 用于去除气道中生物膜的组合物可用于治疗由肺炎支原体引起的肺炎等感染。 通常,组合物包含:(1)一定量的至少一种酶,其催化连接多糖中连接两个单糖或将单糖与糖蛋白中的蛋白质分子连接的键的水解,所述糖蛋白中足以分解生物膜中的生物膜 气道; 和(2)适于施用到气道中的药学上可接受的载体。所述组合物可进一步包含诸如类固醇,溶菌酶,乳铁蛋白或过氧化物酶的成分; 如果包含过氧化物酶,组合物可以进一步包括产生过氧化物的氧化酶以及氧化酶的底物。 基于组合物在气道中溶解生物膜的能力,组合物可用于治疗感染的方法中。
