Disk diffusion interpretive zone size criteria for use with Haemophilus test medium are proposed for five extended-spectrum cephalosporins. With cefuroxime, zones greater than or equal to 24 mm in diameter indicated susceptibility, while zones less than or equal to 20 mm implied resistance. With cefotaxime, ceftizoxime, and ceftriaxone, a single susceptible-zone size, greater than or equal to 26 mm, is proposed.
针对五种超广谱头孢菌素,提出了用于嗜血杆菌测试培养基的纸片扩散法抑菌圈大小判读标准。对于头孢呋辛,直径大于或等于24毫米的抑菌圈表明敏感,而直径小于或等于20毫米的抑菌圈则意味着耐药。对于头孢噻肟、头孢唑肟和头孢曲松,建议采用单一的敏感抑菌圈大小标准,即大于或等于26毫米。
