【摘要】: 細(xì)菌鞭毛染色在細(xì)菌鑒定中是很重要的技術(shù)。由于以前的鞭毛染色方法如Ryu染色法、Leifson染色法、鍍銀染色法、Gray法等都存在著染色液的不穩(wěn)定性,著色欠佳,操作方法復(fù)雜等缺點(diǎn)。2002年,谷海瀛發(fā)表鍍銀染色新方法,該方法具有簡(jiǎn)單、快速、重復(fù)性好、染色后鞭毛清晰等多種優(yōu)點(diǎn)。2005年,谷海瀛、李凡發(fā)表了細(xì)菌液體膜過濾法新技術(shù),用于鞭毛染色,以前細(xì)菌液體培養(yǎng)鞭毛染色都是使用離心法,染色制片菌體不易散開,聚集成團(tuán),背景不干凈.膜過濾法完全克服了這些缺點(diǎn),操作快速,細(xì)菌鞭毛染色效率高。該方法改變了鞭毛肉湯成份,細(xì)菌生長(zhǎng)快速,有利于鞭毛生長(zhǎng)發(fā)育。 1872年首次報(bào)告銅綠假單胞的發(fā)現(xiàn),以前所有文獻(xiàn)報(bào)告銅綠假單胞菌只有1根鞭毛,稱為單端單鞭毛菌,直到2005年谷海瀛首次發(fā)現(xiàn)銅綠假單胞菌具有1-2根鞭毛,稱為單端雙鞭毛。這一發(fā)現(xiàn)是在菌種接種哥倫比亞綿羊血平板培養(yǎng)后鞭毛染色觀察到的。 通過液體培養(yǎng)膜過濾技術(shù)鞭毛染色,比較固體培養(yǎng)和液體培養(yǎng)銅綠假單胞菌雙鞭毛的差別,研究結(jié)果提示:銅綠假單胞菌液體培養(yǎng)雙鞭毛細(xì)胞數(shù)與單鞭毛細(xì)胞數(shù)的比值高于固體培養(yǎng)。
[Abstract]:Bacterial flagellum staining is an important technique in bacterial identification because of the previous flagellum staining methods such as Ryu staining and silver plating staining. In 2002, Gu Haiying published a new method for silver staining, which is simple, rapid and reproducible. In 2005, Gu Haiying and Li Fan published a new technique of bacterial liquid membrane filtration, which was used in flagellum dyeing. The bacteria are not easy to disperse, gather into clusters, and the background is not clean. Membrane filtration method completely overcomes these shortcomings, rapid operation, high efficiency of bacterial flagellum staining. This method changes the flagellum broth composition. The rapid growth of bacteria is beneficial to the development of flagella. In 1872, the discovery of Pseudomonas aeruginosa was first reported. All previous literatures reported that Pseudomonas aeruginosa had only one flagella, known as Monoflagella monocytogenes. Until 2005, Pseudomonas aeruginosa was first found to have 1-2 flagellum, known as double flagellum, in Gu Haiying. This discovery was observed by flagellum staining after inoculated with Colombian sheep blood plate culture. The difference of double flagella between solid culture and liquid culture of Pseudomonas aeruginosa was compared by liquid culture membrane filtration technique. The results showed that the ratio of double flagellum cells to single flagella cells in liquid culture of Pseudomonas aeruginosa was higher than that in solid culture.
