三、細菌的實驗室檢查及其它檢查
1、標(biāo)本采集常為糞便以及食物,也可取血液和尿液等。
糞便標(biāo)本采集要求:采集的動物糞便標(biāo)本應(yīng)新鮮,病人的糞便標(biāo)本最好在發(fā)病3-5病日內(nèi),使用抗生素之前。糞便采集量每份不少于5克,置于干凈塑料袋或置于運送培養(yǎng)基中于6小時內(nèi)送實驗室檢測,夏季標(biāo)本的保存和運送要注意冷藏。原則上每天采集的標(biāo)本可分兩次送至實驗室,即上午的標(biāo)本中午12時前送到,下午的標(biāo)本晚6時前送到,以便于及時開展檢測醫(yī)`學(xué)教育網(wǎng)搜集整理。
2、分離培養(yǎng)——以糞便標(biāo)本為例
(1)冷增菌糞便與改良磷酸鹽緩沖液以1:10混合于4℃增菌,并于10天,20天分別轉(zhuǎn)種麥康凱MAC平板或耶爾森菌屬專用選擇性培養(yǎng)基CIN于25℃培養(yǎng)24~48h.
(2)該菌的菌落在MAC平板上呈無色透明,在CIN平板上呈粉紅色,偶爾有一圈膽鹽沉淀;
(3)將可疑菌落接種改良克氏雙糖培養(yǎng)基25℃培養(yǎng)24h~48h,上、下層均為陽性(即顯黃色)者接種Rustigian氏尿素培養(yǎng)基(使成濃厚菌懸液),振蕩10秒鐘25℃培養(yǎng)2~4h.
(4)尿素陽性者再接種半固體各2管,1管于25℃培養(yǎng)24h,另1管于37℃培養(yǎng)24h.該菌在25℃動力陰性,37℃動力陰性。
3、生化鑒定(25℃培養(yǎng)):典型小腸結(jié)腸炎耶爾森菌主要的生化反應(yīng)情況:脲酶陽性、硫化氫陰性、VP25℃陽性、鳥氨酸脫羧酶陽性。發(fā)酵葡萄糖、蔗糖產(chǎn)酸不產(chǎn)氣,不發(fā)酵密二糖和鼠李糖。
4、血清分型。
