Legionnaires' disease is a clinical syndrome caused by Legionella bacteria. Philadelphia, United States in 1976 held a veteran assembly was named after the outbreak. Pathogen mainly from the soil and sewage, spread by air, from the respiratory tract invasion. According to the 2007 World Health Organization (WHO) guidelines, Legionnaires 'disease is divided into three subtypes: (1) pneumonia-type Legionnaires' disease (LD) with pneumonia as the main clinical manifestation of Legionella infection, also known as Legionella pneumonia; Syndrome that spread from the lungs to other systems outside the lungs; ③ Pontiac fever mainly for acute fever, duration was self-limiting. The main pathogen of Legionnaires' disease is Legionella pneumophila serotype 1. More men than women. Elderly people, smokers and people with immunocompromised people are predisposed to the disease.

軍團(tuán)菌IFA IgM熒光試劑盒
產(chǎn)品名稱:檢測(cè)人血清/血漿抗病毒抗體IgG的間接免疫熒光檢測(cè)試劑盒
【包裝規(guī)格】 25人份/盒
簡(jiǎn)介:軍團(tuán)桿菌,系需氧革蘭氏陰性桿菌,以嗜肺軍團(tuán)菌zui易致病?,F(xiàn)已提出了超過30種軍團(tuán)桿菌,至少19種是人類肺炎的病原。其中zui常見病原體為嗜肺軍團(tuán)菌(占病例的85%~90%),其次是L.micdadei(占5%~10%),再次是L.bozemanii和L.dumoffii.此類細(xì)菌形態(tài)相似,具有共同的生化特征,引起類似疾病。
測(cè)試原理:IFA方法是基于樣品中抗體的反應(yīng),用吸附在滑動(dòng)表面上的抗原進(jìn)行測(cè)試。樣品中的特異性抗體與抗原發(fā)生反應(yīng),而不與抗原結(jié)合的免疫球蛋白在洗滌步驟中被除去。下一步,抗原抗體復(fù)合物與熒光素標(biāo)記的抗人球蛋白反應(yīng)。它可以用免疫熒光顯微鏡檢查。
試劑盒的特點(diǎn):除PBS外,所有試劑均已備好使用。所有這些試劑有一個(gè)便于識(shí)別的號(hào)碼。在分析過程中,每一步使用的試劑的用量都表明了。
試劑盒內(nèi)容(詳情請(qǐng)參考英文原版):
1、病毒玻片:玻片的腺病毒10的10威爾斯,涂腺病毒感染Hep-2細(xì)胞,腺樣體71株(ATCC VR-1),甲醛處理,丙酮固定和混合與非感染細(xì)胞。
2、PBS:1瓶PBS pH 7.2粉重建與蒸餾水1升。
3、病毒IgG陽性對(duì)照:200μL陽性對(duì)照血清,含疊氮鈉。
4、病毒陰性對(duì)照:陰性對(duì)照血清200μL,含疊氮鈉。
5、g抗-人IgG FITC共軛:2瓶1.1毫升的熒光素標(biāo)記的抗人IgG熒光共軛在含Evan′s blue的磷酸鹽緩沖液,huana和蛋白質(zhì)穩(wěn)定劑。
6、安裝介質(zhì):安裝介質(zhì)3 mL緩沖甘油,含有huana。
存儲(chǔ)要求:
按建議的溫度存儲(chǔ)。不要使用超過保質(zhì)期的試劑盒。只有當(dāng)試劑被封上并儲(chǔ)存在的溫度時(shí),才會(huì)有效。
試劑的穩(wěn)定性和操作:
在無菌條件下處理試劑以避免微生物污染物。
只使用需要測(cè)試的PBS,控制血清和共軛溶液的數(shù)量。不要把多余的溶液倒進(jìn)瓶子里。重組后,儲(chǔ)存PBS在2-8oC中,如果有濁度出現(xiàn),請(qǐng)停止使用。
標(biāo)本采集與處理:
無菌采集血液必須使用靜脈穿刺技術(shù)。無菌或無菌技術(shù)的使用將保持標(biāo)本的完整性。
血清/血漿樣品被冷藏(2-8oC)在收集或冷凍(20oC)如果在7天內(nèi)完成測(cè)試,不能。樣品不應(yīng)反復(fù)冷凍和解凍。不要使用高脂血、溶血、污染樣本。含有顆粒的樣品應(yīng)通過離心澄清。該試劑盒適合于血清或血漿使用。
試劑的初步制備:
只有PBS必須事先準(zhǔn)備好。將小瓶2的含量添加到1升蒸餾水中。搖勻直至*溶解。一旦稀釋,保存在2-8度。
局限性:
1、此試劑盒用于與人血清/血漿結(jié)合使用。
2、該工具包的用戶建議仔細(xì)閱讀和理解包插入。為了獲得可靠的測(cè)試結(jié)果,必須嚴(yán)格遵守該協(xié)議。特別是,正確的樣品和試劑的加樣,隨著孵育步驟仔細(xì)清洗和時(shí)機(jī)是*的準(zhǔn)確的結(jié)果。
3、樣品的結(jié)果應(yīng)與臨床評(píng)價(jià)和其他診斷程序結(jié)合使用。隔離技術(shù)應(yīng)作出明確診斷。
4、此測(cè)試不會(huì)顯示感染部位。它并不打算取代孤立。
5、抗體水平的顯著升高并不排除感染可能性。
6、在感染過程中很早采集的樣本可能沒有檢測(cè)到IgG水平。在這種情況下,建議進(jìn)行IgM檢測(cè),或第二次血清樣本,14至21天后,與原樣品平行測(cè)試,以確定血清轉(zhuǎn)換。
7、由于孕婦IgG在分娩前被動(dòng)地從母體傳遞到胎兒,因此必須謹(jǐn)慎地對(duì)其進(jìn)行檢測(cè)。IgM檢測(cè)通常是6個(gè)月以下兒童感染的有用指標(biāo)。
8、單一樣本抗體測(cè)定結(jié)果不應(yīng)用于診斷zui近感染。配對(duì)樣本(急性期和恢復(fù)期)應(yīng)同時(shí)進(jìn)行檢測(cè),以尋找血清轉(zhuǎn)換或抗體水平顯著上升。
9。自身免疫病患者的樣本在使用IFA時(shí)可能會(huì)對(duì)細(xì)胞產(chǎn)生非特異性反應(yīng)。不能用這種方法對(duì)那些樣品進(jìn)行評(píng)估。
10。性能測(cè)試結(jié)果顯示對(duì)應(yīng)于商業(yè)預(yù)測(cè)設(shè)備的比較研究在一個(gè)確定的人口樣本。小的差異可以發(fā)現(xiàn),不同群體或不同的預(yù)測(cè)裝置。
實(shí)驗(yàn)步驟
1) 將所有的材料和樣品都平衡至室溫(15-30℃)
2) 將所有的檢測(cè)卡從密封的試劑袋中取出。
3) 將樣品點(diǎn)滴器垂直置于樣品孔上方,向樣品孔中加入3滴樣品(120-150ul)。
4) 10分鐘內(nèi)讀取結(jié)果,強(qiáng)陽性樣品可能會(huì)早點(diǎn)出現(xiàn)結(jié)果。
注意:10分鐘后讀取的實(shí)驗(yàn)結(jié)果可能會(huì)不準(zhǔn)確。
結(jié)果說明
陽性結(jié)果:檢測(cè)線區(qū)域出現(xiàn)明顯的粉色條帶,另外質(zhì)控線區(qū)域出現(xiàn)粉色條帶。
陰性結(jié)果:檢測(cè)線區(qū)域不顯色,質(zhì)控線區(qū)域出現(xiàn)明顯的粉色條帶。
無效結(jié)果:靠近檢測(cè)線的質(zhì)控線在加樣品后15分鐘內(nèi)不可見的話,則實(shí)驗(yàn)結(jié)果無效。
我司還提供其它進(jìn)口或國(guó)產(chǎn)試劑盒:登革熱、瘧疾、流感、A鏈球菌、合胞病毒、腮病毒、乙腦、寨卡、黃熱病、基孔肯雅熱、克錐蟲病、違禁品濫用、肺炎球菌、軍團(tuán)菌、化妝品檢測(cè)、食品安全檢測(cè)等試劑盒以及日本生研細(xì)菌分型診斷血清、德國(guó)SiFin診斷血清、丹麥SSI診斷血清等產(chǎn)品。

IMfectious Aedes mosquito bites the humaM body, the virus spread to humaMs. Aedes mosquitoes were presumed to be the storage hosts of the virus because DeMgue virus particles were detected iM the ovaries that captured Aedes mosquitoes.
