Abstract
A new chromogenic cephalosporin, pyridinium-2-azo-p-dimethylaniline chromophore, was evaluated for use in a rapid paper strip or tube test for the detection of beta-lactamases from a variety of microorganisms. A 1-min pyridinium-2-azo-p-dimethylaniline chromophore paper strip test was found to be a convenient and accurate method for the detection of beta-lactamase-producing strains of Haemophilus influenzae and Neisseria gonorrhoeae, although it could not be relied upon to detect beta-lactamases produced by staphylococci, enteric organisms, or Bacteroides fragilis.
摘要
一种新型显色头孢菌素，即吡啶 - 2 - 偶氮 - 对二甲苯胺发色团，被评估用于一种快速纸条或试管试验，以检测来自多种微生物的β - 内酰胺酶。结果发现，1分钟的吡啶 - 2 - 偶氮 - 对二甲苯胺发色团纸条试验是检测产β - 内酰胺酶的流感嗜血杆菌和淋病奈瑟菌菌株的一种方便且准确的方法，尽管它无法可靠地检测葡萄球菌、肠道菌或脆弱拟杆菌产生的β - 内酰胺酶。
