A modified oxidase reagent, 1% tetramethyl-p-phenylenediamine in dimethyl sulfoxide, proved superior to the routinely used 1% aqueous tetramethyl-p-phenylenediamine dihydrochloride in detecting weakly oxidase-positive gram-negative bacteria after 24 h of growth on agar media (40 of 40 positive versus 22 of 40 positive). The bacterial inoculum was obtained with a cotton-tipped swab instead of a loop or wooden applicator, and the reaction required less than 15 s.
一种改良的氧化酶试剂,即二甲基亚砜中1%的四甲基对苯二胺,在琼脂培养基上培养24小时后,在检测弱氧化酶阳性革兰氏阴性菌方面,被证明优于常规使用的1%盐酸四甲基对苯二胺水溶液(40株中有40株呈阳性,而40株中只有22株呈阳性)。细菌接种物是用棉签而不是接种环或木制涂抹器获取的,反应时间不到15秒。
