介紹
以急性發熱性呼吸道癥狀為特征的退伍軍人癥是由吸入含有嗜肺軍團菌的霧化水引起的。嗜肺軍團菌血清組1zui常從患者中分離(1,2)。
IMMUNOCATCHTM軍團菌(Legionella)是一種側流免疫層析法,可通過快速可靠地檢測尿樣中的抗原,對嗜肺軍團菌血清型1感染進行早期診斷。
原理
本產品是一種試劑盒,設計用于免疫層析法檢測尿樣中嗜肺軍團菌血清型1 LPS抗原。
當樣品通過毛細作用遷移通過結合墊時,樣品中的軍團菌抗原與綴合至膠體顆粒的抗軍團菌抗體結合形成抗原 - 抗體復合物。抗原 - 抗體復合物在試紙條上遷移,與固定在膜上的抗軍團菌抗體特異性結合而產生紅線。然后通過肉眼觀察紅線的存在來確定軍團菌抗原的存在。
此外,抗-Legionella抗體偶聯的膠體金在反應中不被消耗,與固定在對照線上的抗免疫球蛋白抗體結合產生紅線,表明在測試條上的反應是成功的。
【包裝規格】20T/盒
【檢測方法】
1)從鋁袋中取出所需數量的磁帶,并將它們放在水平面上。
2)使用定量移液器慢慢地吸取90μL或更多的樣品。 通過一次移液操作,將全部樣品滴入盒子的樣品位置。 滴下后,剩余的標本留在吸管內。
3)在室溫(15-30°C)下將盒子放置15分鐘,
4)檢查盒子評估地點是否有線(標有“C”和“T”)。
結果
應該在反應開始15分鐘后及時進行評估。 檢查評估地點,并通過下面描述的紅線來評估結果。
1)正面:紅色控制線和測試線均在評估現場。 當兩條線在反應時間結束之前出現時結果是肯定的。
2)否定的:評估地點只有一條紅色的控制線。
3)無效:無論控制線是否存在,無論是否存在測試線,測試均無效。
一、臨床實驗室診斷
產氣莢膜梭菌病的正確確診需根據以下幾個方面:
1、小腸內檢測出大量毒素;2、腸道內有大量產氣莢膜梭菌;3、腎臟、肝臟等實質器官發現產氣莢膜梭菌和其毒素;4、尿液含有葡萄糖。二、產氣莢膜梭菌毒素檢測
產氣莢膜梭菌毒素檢測的經典方法有:1、動物致死性試驗:將腸道內容物稀釋取上清攻毒小白鼠,觀察小白鼠致死情況;2、毒素中和試驗法:是更佳準確的方法,提取的毒素與毒素抗體中和后攻毒小白鼠,若對照組死亡,中和組不死亡,則精確表明某型毒素致死;3、卵磷脂水解試驗法:α毒素能分解卵磷脂,產氣莢膜梭菌所有型均能產生α毒素,能驗證產氣莢膜梭菌的存在。這些較為常用的方法中,以毒素中和試驗zui為特異,但相對而言這些方法均較費時費力,且敏感性較低。三、分子生物學診斷方法隨著生物科學技術的快速發展,一些分子水平上的檢測方法在毒素檢測上得到了遍應用。Kadra等為了驗證PCR的準確可靠性,用PCR方法對不同來源的產氣莢膜梭菌及毒素進行分型驗證,將90株產氣莢膜梭菌用細菌生化試驗等方法進行驗證,然后用小鼠血清中和試驗進行定型,再用PCR法擴增α、β和ε三種毒素基因片段,zui后將兩種定型方法鑒定的血清型進行驗證,結果表明,兩種方法定型*。表明PCR法準確可靠,且比小鼠的血清中和試驗節約成本,方便可靠。于曉霞等為了尋找一種快速、準確的方法檢測產氣莢膜梭菌毒素型,采用SDS-PAGE的方法,對不同的產氣莢膜梭菌分離株所產的外毒素蛋白進行分子量測定,從而確定所產外毒素的種類,確定菌株型。Fach等首先研究了用聚合酶鏈反應(PCR)方法檢測毒素,參考毒素其他桿菌的磷脂酶C基因,設計了保守區域的針對基因特異性的引物,用PCR法擴增除了基因片段與毒素基因內的序列**,表明可以使用PCR方法檢測毒素基因,從而驗證細菌型。Warren等應用PCR方法對包埋在福爾馬林里的含有產氣莢膜梭菌的病料進行基因檢測,擴增到了α、β和ε毒素基因,雖然產氣莢膜梭菌已經死亡,但產氣莢膜梭菌基因依然沒有被破壞,因而PCR方法可以檢測死亡產氣莢膜梭菌的存在。
可溶性抗原與相應抗體持異性結合,兩者比例適當并有電解質存在及一定的溫度條件下,經一定的時間,可形成肉眼可見的沉淀物,稱為沉淀反應(precipitation)。

First, clinical laboratory diagnosis
The correct diagnosis of Clostridium perfringens need to be based on the following aspects:
1, a large number of toxins detected in the small intestine; 2, a large amount of Clostridium perfringens in the intestine; 3, Clostridium perfringens and its toxins found in the real organs such as the kidney and liver; 4, urine containing glucose. Second, Clostridium perfringens toxin detection
Clostridium perfringens toxin detection of the classic methods are: 1, animal lethal test: the intestinal contents of the supernatant to attack the mice were diluted to observe the lethality of mice; 2, toxins and test method: is more Good and accurate method, extracted toxins and toxin antibodies and challenge the mice, if the control group died, the neutralization group does not die, then precisely that a toxin toxin; 3, lecithin hydrolysis test: alpha toxin can break down Lecithin, all of Clostridium perfringens, produce alpha toxins and can confirm the presence of Clostridium perfringens. Of these more commonly used methods, toxin neutralization test is the most specific, but relatively speaking, these methods are more time-consuming and less sensitive. Third, molecular biology diagnostic methods With the rapid development of biological science and technology, some of the molecular level detection methods in the toxin detection has been applied. Kadra et al. In order to verify the accuracy and reliability of PCR, the Clostridium perfringens and toxin from different sources were identified by PCR. 90 strains of Clostridium perfringens were confirmed by the method of bacterial biochemistry, The mouse serum neutralization test was performed. The three α, β and ε toxin gene fragments were amplified by PCR. Finally, the serotypes identified by the two typing methods were validated. The results showed that the two methods were consistent. PCR method is accurate and reliable, and cost-saving than the mouse serum neutralization test, convenient and reliable. Yu Xiaoxia and so in order to find a rapid and accurate method for the detection of Clostridium perfringens toxin type, using SDS-PAGE method, different Clostridium perfringens isolates of exotoxin protein molecular weight determination , To determine the type of exotoxin produced, to determine the strain type. Fach et al first studied the use of polymerase chain reaction (PCR) detection of toxins, with reference to other phospholipase C toxins gene, designed a conserved region of the gene-specific primers, amplified by PCR in addition to gene fragments and toxins gene The exact sequence within the sequence indicates that the toxin gene can be detected using the PCR method to verify the bacterial species. Warren et al. Used PCR to detect the genes encoding C. perfringens embedded in formalin and amplified the alpha, beta, and etoxin genes. Although Clostridium perfringens has died, However, the Clostridium perfringens gene is still intact, and thus the PCR assay can detect the presence of Clostridium perfringens death.
Soluble antigens with the corresponding antibodies heterosexual combination of both the appropriate ratio and the presence of electrolytes and a certain temperature conditions, after a certain period of time, can form a visible sediment, called precipitation.
