(三)明膠液化試驗
1、接種:用穿刺接種法接種大腸桿菌或產(chǎn)氣腸桿菌于明膠培養(yǎng)基中。
2、培養(yǎng):放20℃恒溫箱中培養(yǎng)48h。若細菌在20℃下不長,則應(yīng)放在zui適溫度下培養(yǎng)。
3、觀察結(jié)果:觀察培養(yǎng)基有無液化情況及液化后的形狀。
因明膠在低于20℃時凝固,高于25℃時自行液化,若是在高于20℃下培養(yǎng)的細菌,觀察時應(yīng)放在冰浴中觀察,若明膠被細菌液化,即使在低溫下明膠也不會再凝固。
(四)石蕊牛乳試驗
1、接種:將黏乳產(chǎn)堿桿菌和銅綠假單胞菌接種入石蕊牛乳培養(yǎng)基中。
2、培養(yǎng):將接種后的試管于37℃恒溫培養(yǎng)7d,另外保留一支不接種的石蕊牛乳培養(yǎng)基作為對照。
3、結(jié)果觀察:取出培養(yǎng)物,以不接種任何細菌的試管為對照,觀察接種不同細菌生長后的變化情況。
試驗目的 血清分型
標本 出血熱恢復期病人血清
材料
1、 毒株 漢灘病毒標準株 76-118,漢城病毒標準株 Seoul;
2、標準血清 兔抗?jié)h灘病毒、漢城病毒血清;
3、空斑減少中和試驗常用試劑。
步驟
1、將待檢血清用牛血清Hanks 氏液稀釋成1:10,56℃滅活30分鐘;
2、進一步2倍稀釋血清成1:20、1:40、1:80……,對照血清1:10稀釋;
3、稀釋兩種病毒(在冰浴中進行)至含200pfu/ml;
4、各連續(xù)稀釋度血清分別與200pfu/ml的兩種病毒液等量混合(各0.3ml),置37℃中作用1小時(每15分鐘振蕩一次);
5、吸出各細胞培養(yǎng)孔中維持液;
6、接種長滿單層的Vero-E6細胞(24孔板),每孔接種血清病毒混合液、標準血清對照及兩種病毒對照 ,每稀釋度兩孔,100ul/孔。37℃吸附1小時,每隔15分鐘搖動一次;
7、加*層瓊脂糖覆蓋液(需冷置42℃左右),每孔1ml,室溫下待凝固,細胞面朝上,置37℃5%CO2孵箱培養(yǎng)7-9天;
8、加第二層含中性紅瓊脂糖覆蓋液,1ml/孔,室溫下待凝固,細胞面朝上,置37℃5%CO2孵箱培養(yǎng)2-5天,從第二天開始觀察空斑數(shù);
9、抗體滴度的判定,以比病毒對照的空斑數(shù)中和或減少50%的血清zui高稀釋度倒數(shù)判為待檢血清中和抗體滴度;
10、型別判定:根據(jù)同一份血清與兩種病毒的反應(yīng)滴度不同來區(qū)分,如果一份血清與漢灘病毒 (或漢城病毒)反應(yīng)的抗體滴度高于與漢城病毒(漢灘病毒)的抗體滴度4倍或以上,即判為漢灘病毒型,反之則為漢城病毒型。兩者滴度相差無幾時,則不好分型。不足4倍時亦不能定型。

(C) gelatin liquefaction test
1, inoculation: Inoculation with puncture inoculation of E. coli or Enterobacter aerogenes in gelatin medium.
2, training: put 20 ℃ incubator cultured 48h. If the bacteria is not long at 20 ° C, it should be cultured at the optimum temperature.
3, the observation results: observe the presence or absence of liquefaction medium and liquefied shape.
Because gelatin below 20 ℃ coagulation, higher than 25 ℃ liquefaction, if the bacteria cultured at more than 20 ℃, the observation should be placed in an ice bath to observe, if the gelatin is bacterial liquefaction, even at low temperatures gelatin Will not be solidified again.
(D) Litmus milk test
Inoculation: Enterobacter viscosus and Pseudomonas aeruginosa were inoculated into the litmus milk culture medium.
2, Culture: The inoculated tubes were incubated at 37 ° C for 7 days, and a non-inoculated litmus culture medium was kept as a control.
3, the results observed: Remove the culture, with no inoculation of any bacteria in vitro as a control, observe the changes after inoculation of different bacteria growth.
The purpose of the test serotyping
Specimen hemorrhagic fever convalescent patient serum
material
1, strain of Hantaan virus standard strain 76-118, Seoul virus standard strain Seoul;
2, the standard serum rabbit anti-Hantaan virus, Seoul virus serum;
3, plaque reduction and neutralization test commonly used reagents.
step
1, the serum to be seized diluted 1: 10 with bovine serum Hanks solution, 56 ℃ inactivated 30 minutes;
2, further 2-fold dilution of serum into 1: 20,1: 40,1: 80 ..., the control serum 1:10 dilution;
3. Dilute both viruses (in an ice bath) to 200 pfu / ml;
4, each serial dilutions of serum were mixed with 200pfu / ml two kinds of virus solution (each 0.3ml), set 37 ℃ for 1 hour (every 15 minutes oscillation);
5, Aspirate the cells in each well to maintain fluid;
6. Inoculate monolayer of Vero-E6 cells (24-well plate) and inoculate each well with serum virus mixture, standard serum control and two virus controls, two wells per dilution, 100 ul / well. 37 ℃ adsorption 1 hour, every 15 minutes to shake once;
7, add the first layer of agarose cover solution (need to cool about 42 ℃), 1ml per well, to be solidified at room temperature, cell surface up, set 37 ℃ 5% CO2 incubator for 7-9 days;
8, add a second layer containing neutral red agarose cover solution, 1ml / well, to be solidified at room temperature, cell surface up, set 37 ℃ 5% CO2 incubator for 2-5 days, starting from the next observation empty Number of spots
9, the determination of antibody titer, compared with the number of plaque virus control neutralization or reduction of 50% of the serum maximum dilution countdown to be seized serum neutralizing antibody titer;
10, the type of judgment: According to the same serum and two kinds of virus reaction titer to distinguish, if a serum and Hantaan virus (or Seoul virus) antibody titers higher than the reaction with the Seoul virus (Hantaan virus) Of the antibody titers 4 times or more, that is sentenced to Hantaan virus type, and vice versa is Seoul virus type. When titer difference between the two is not good, then the type is not good. Less than 4 times can not be stereotyped.
