一般說明

氧化酶试验试剂(Gordon-McLeod法)是实验室常用的微生物学试剂,用于检测产出细胞色素c氧化酶的细菌。试剂用于确定酶的存在,该酶是电子传递链的重要组成部分,代表细菌中存在呼吸代谢。Gordon-McLeod试剂含有N,N,N′,N′-四甲基对苯二胺二盐酸盐,作为活性组分。当细菌产出细胞色素c氧化酶,该试剂就会发生变色反应,从无色变为蓝色或紫色。这种变色的阳性结果说明受检菌株具有细胞色素c氧化酶活性。

應用

氧化酶试验试剂(Gordon-McLeod法)是实验室常用的工业微生物学检测方法,用于根据产出细胞色素c氧化酶的能力来区分不同菌株。Gaby-Hadley A试剂提供鉴定假单胞菌、弧菌和某些奈瑟氏菌等氧化酶阳性菌的简单高效方法,而缺乏细胞色素c氧化酶的微生物就会呈现阴性结果。适合食品、饮料和制药行业。

Vibrios are motile, curved or comma-shaped bacilli and have a single polar flagella with sheet proteins. They are often found in open water, freshwater and saltwater.

On the Trail of Campylobacter - The Campylobacter is one of the leading causes of human gastroenteritis. Common Campylobacter species C. jejuni, C. coli, and C. lari are responsible for most cases of campylobacteriosis. However, other species, like C. fetus, which causes spontaneous abortions, have also been associated with human illness. Campylobacter are Gram-negative, spiral-shaped, microaerophilic and motile bacteria with uni- or bi-polar fl agella

Chromogenic media enable the selective detection of S. aureus, which produce bluish-green colonies that are clearly differentiated from other species.
