Detection of beta-lactamase by four different techniques (two acidometric, one chromogenic cephalosporin, and one iodometric) was evaluated with 79 isolates of nine different species of staphylococci. Overall, each technique detected more positive isolates when beta-lactamase production had been induced with oxacillin before testing, and each technique performed equally well when organisms were tested after induction.
采用四种不同技术（两种酸度测定法、一种显色头孢菌素法和一种碘量法）对9种不同葡萄球菌的79株分离株进行β-内酰胺酶检测。总体而言，在检测前用苯唑西林诱导产生β-内酰胺酶时，每种技术检测到的阳性分离株更多；当对诱导后的菌株进行检测时，每种技术的表现同样出色。
