【檢驗原理】本品采用競爭抑制法和膠體金免疫層析法原理定性檢測尿液中的尼古丁,以金標尼古丁單克隆抗體作為指示標記物,在硝酸纖維素膜上的檢測線處和控制線處分別包被尼古丁-BSA結合物和羊抗鼠IgG多克隆抗體。檢測時,尿樣在毛細效應下層析。如尿樣中的尼古丁濃度低于200ng/mL時,金標抗體不能全部與尼古丁結合,未結合的金標抗體在層析過程中與固定在檢測線處的尼古丁-BSA結合物結合,從而在檢測區(T)出現一條紫紅色條帶;如尿樣中尼古丁濃度高于200ng/mL時,金標抗體全部與尼古丁結合,從而在檢測區(T)因為競爭反應不會與尼古丁-BSA結合物結合而不出現紫紅色條帶。無論尿樣中是否存在尼古丁,控制區(C)都會出現一條紫紅色條帶。控制區(C)所呈現的紫紅色條帶是判斷是否有足夠的尿樣,層析過程是否正常的標準,同時也作為試劑的內控標準。

在我國,產氣莢膜梭菌病在20世紀80年代就有零星發生,以犢牛發病為主,90年代以來,該病日趨嚴重,牛的發病數量急速增多,發病地區也不斷擴大,目前該病已廣泛分布于全國各地,嚴重危害中國畜牧業的發展。
一、流行特點產氣莢膜梭菌能使不同年齡不同品種的牛(包括黃牛、奶牛、水牛等)發病,主要呈零星散發或區域性流行,一般可波及幾個至十幾個鄉鎮或牛場。該病以農區和半農半牧區多發,常流行于低洼、潮濕地區,一年四季均有發生,但春末、秋初及氣候突然變化時發病率明顯升高。耕牛以4-6月份發病較多,奶牛、犢牛以4-5月、10-11月發病較多,牦牛以7-8月發病較多。病程長短不一,短則數分鐘至數小時,長則3-4d或更長。發病時有的集中在同圈或毗鄰舍,有的呈跳生物發生,發病間隔時間長短不一,有的間隔幾天、十幾天,有的間隔幾個月。近年國內各地發生的產氣莢膜梭菌病以A和D型為主要病原菌。
二、發病原因1)菌株因素:根據現有文獻,各型產氣莢膜梭菌均能引起牛發病,尤以A、C、D型居多。國外報道的產氣莢膜梭菌病以C、D型菌導致牛的壞死性腸炎或腸毒血癥較多,而我國產氣莢膜梭菌病則以A型菌導致的牛“猝死癥”為主,也有C、D型菌致病。E型僅見于野生牦牛產氣莢膜梭菌性腸炎的報道,其發病率較高,可達42.86%,病死率較低,為14.3%。另外,A、C和D型的某些菌株還能產生腸毒素,它不同于該菌的其他毒素,是導致牛腹瀉的主要原因,犢牛zui易發生。近年來多見D型菌導致牛腸毒血癥的報道,成年牛和犢牛均有發生,該病死亡突然,危害極大,黑龍生物、生物海、云南、寧夏等地均有相關的報道。
(2)環境因素:產氣莢膜梭菌是典型的條件性致病菌。大量研究表明,產氣莢膜梭菌在牛腸道和畜舍環境中普遍存在。由于畜舍中的糞便來源于動物胃腸道,空氣中的產氣莢膜梭菌多來源于動物糞便,環境中存在的產氣莢膜梭菌與動物體內的產氣莢膜梭菌密切相關。細菌是源于糞便。

In China, Clostridium perfringens disease sporadically occurred in the 1980s, with calf incidence mainly, the disease has become increasingly serious since the 1990s, the rapid increase in the number of cattle incidence, the incidence of the region has also been expanding, the current The disease has been widely distributed throughout the country, seriously endangering the development of animal husbandry in China.
First, the popular features Clostridium perfringens can make different age groups of cattle (including cattle, dairy cows, buffalo, etc.) incidence, mainly sporadic distribution or regional epidemic, generally can affect a few to a dozen towns or cattle field. The disease in rural and semi-agricultural and pastoral areas prone, often endemic in low-lying, humid areas occur all year round, but the late spring and early autumn and sudden changes in climate incidence was significantly higher. Cattle in April-June more incidence, dairy cows, calves in April-May, 10-11 months more incidence, yak in July-August more disease. Duration varies, ranging from a few minutes to several hours, 3-4d long or longer. Occurrence of some focus on the same circle or adjacent homes, and some were jumping creatures, the incidence of varying length of time, some intervals of a few days, a dozen days, and some intervals of a few months. In recent years, Clostridium perfringens occurred around the country to A and D-type as the main pathogen.
Second, the cause of the disease 1) strain factors: According to the existing literature, each type of Clostridium perfringens can cause cattle disease, especially A, C, D-type mostly. Clostridium perfringens reported abroad Clostridium C, D-type bacteria lead to necrotic enteritis or enterotoxemia more cattle, Clostridium perfringens disease is caused by the type A bacteria of the sudden death of cattle "Based, there are C, D-type pathogenic bacteria. Type E was only found in wild yak C. perfringens enteritis, which reported a high incidence of 42.86% with a low case fatality rate of 14.3%. In addition, some strains of type A, C and D also produce enterotoxins, which are different from other toxins in the bacterium and are the main cause of diarrhea in cattle. In recent years more common cause of D-type enterotoxemia caused by the reports of adult calves and cattle have occurred, the sudden death of the disease, endangering, Black Dragon, bio-sea, Yunnan, Ningxia and other places are related reports .
(2) Environmental factors: Clostridium perfringens is a typical pathogenic bacteria. Numerous studies have shown that Clostridium perfringens is ubiquitous in the gut and barn environments. Since the manure in the barn is derived from the gastrointestinal tract of animals, Clostridium perfringens in the air mostly comes from animal excrement, and Clostridium perfringens present in the environment is closely related to Clostridium perfringens in animals .
