原理
銅綠假單胞菌(又名綠膿桿菌)是革蘭氏陰性桿狀需氧菌。正如其他假單胞菌一樣,銅綠假單胞菌分泌幾種的色素,包括綠膿素(藍(lán)綠色)、熒光素(黃綠色,發(fā)熒光)、紅膿素(棕紅色)。King等人開發(fā)了假單胞菌瓊脂P(又稱King A培養(yǎng)基),用于提高綠膿素和紅膿素的產(chǎn)出,以及假單胞菌瓊脂F(xiàn)(又稱King B 培養(yǎng)基)用于提升熒光素的產(chǎn)出【1】。
該顯色培養(yǎng)基用植物源蛋白胨取代動(dòng)物蛋白胨,并基于King 等人的配方而成(熒光混合劑除外)。它是選擇性培養(yǎng)基,用于從膿液、痰和引流液等樣本中分離銅綠假單胞菌。
培養(yǎng)基中的溴棕*銨抑制其他菌群生長。它作為季銨類化合物和陽離子表面活性劑,使銅綠假單胞菌之外的細(xì)菌菌體釋放出氮和磷。銅綠假單胞菌裂解熒光底物,使UV下發(fā)射熒光。
