The DOA Panels are one-step immunoassay in which chemically labeled drugs (drug-protein conjugates) compete for limited antibody binding sites with drugs which may be present in urine. The test device contains membrane strips which are pre-coated with drug-protein conjugates on the test band(s). Each strip, the drug antibody-colloidal gold conjugate pad is placed at one end of the membrane. In the absence of drug in the urine, the solution of the colored antibody-colloidal gold conjugate move along with the sample solution upward chromatographically by capillary action across the membrane to the immobilized drug-protein conjugate zone on the test band region. The colored antibody-gold conjugate then attach to the drug-protein conjugates to form visible lines as the antibody complex with the drug conjugate. Therefore, the formation of the visible precipitant in the test zone occurs when the test urine is negative for the drug. When the drug is present in the urine, the drug/metabolite antigen competes with drug-protein conjugate on the test band region for the limited antibody. When a sufficient concentration of the drug is present, it will fill the limited antibody binding sites. This will prevent attachment of the colored antibody (drug-protein conjugate)-colloidal gold conjugate to the drug-protein conjugate zone on the test band region. Therefore, absence of the color band on the test region indicates a positive result.
A control band with a different antigen/antibody reaction is added to the immunochromatographic membrane strip at the control region (C) to indicate that the test has performed properly. This control line should always appear regardless of the presence of drug or metabolite. If the control line does not appear the test device should be discarded.

如果人體內(nèi)也能夠找到具有相似特征的細菌，就有辦法治療由超級細菌引發(fā)的感染類疾細菌。
研究人員以小鼠為實驗對象，發(fā)現(xiàn)部分小鼠能夠抵抗細菌原菌感染引發(fā)的肌肉細菌。通過比較這一類小鼠與其它小鼠體腸道內(nèi)的腸道菌群，發(fā)現(xiàn)一株大腸桿菌只存在于抗肌肉細菌的小鼠體內(nèi)。當普通小鼠通過飼喂定殖這種大腸桿菌后，它們也獲得了在感染期間抗肌肉細菌的能力。進一步研究發(fā)現(xiàn)，在感染期間，這種超級英雄大腸桿菌能夠從腸道遷移到脂肪組織，從而介導了肌肉組織的保護效應。
一般情形下，肺部或腸道感染的小鼠體內(nèi)的胰島素樣因子-1（insulin-like growth factor 1，IGF-1）水平會下降，這一激素因子是維持肌肉的主要信號分子。保護性超級英雄大腸桿菌能夠激活IGF-1信號通路，使IGF-1保持在一個正細菌的水平，因此盡管在感染期間，仍然保證了肌肉組織的穩(wěn)定。
目前還不清楚在人體內(nèi)是否也存在著這類超級英雄細菌，這類超級英雄細菌是否能用于治療人體感染也不清楚。雖然目前仍有許多問題需要解釋，不過，利用超級英雄細菌抑制細菌原菌感染對機體造成的損害，而不是去殺滅致細菌菌本身，是治療細菌原菌感染的一個新思路。研究發(fā)現(xiàn)，豬藍耳細菌毒（PRRSv）和圓環(huán)細菌毒（PCV2）均可與細菌生物膜關聯(lián)共存，這意味著細菌可能是這兩種細菌毒的傳播載體，并且由于細菌生物膜的保護作用，使消毒劑對這兩種細菌毒的作用大打折扣。
來自加拿大蒙特利爾大學、拉瓦爾大學的5位科學家，經(jīng)初步試驗研究證明PRRSv和PCV2 可與細菌生物膜共存，并且能在生物膜內(nèi)存活數(shù)天。
細菌細胞形成的結(jié)構簇
在這項研究中，科研人員將“生物膜”定義為“粘附在物體表面上的，由細菌自發(fā)形成的具有結(jié)構性的聚合物基質(zhì)”。
研究者認為這種生物膜可能會起到保護細菌毒的作用，科研人員說：我們因此假設養(yǎng)豬生產(chǎn)中一些重要細菌毒可能會與這種生物膜結(jié)構關聯(lián)存在，并且在這種生物膜的保護下，使這些細菌毒在豬場環(huán)境中存活很長時間。

If the body can also find bacteria with similar characteristics, there is a way to treat bacterial infections caused by superbugs.
The researchers used mice as experimental subjects and found that some mice were able to resist muscle bacteria caused by bacterial infections. By comparing the gut microbiota in this group of mice with other mice, one strain of E. coli was found only in mice that are resistant to muscle bacteria. When ordinary mice colonize this E. coli by feeding, they also gain the ability to fight muscle bacteria during infection. Further research found that during infection, the superheroE. Coli can migrate from the gut to adipose tissue, mediating the protective effect of muscle tissue.
In general, the level of insulin-like growth factor 1 (IGF-1) in lung or gut-infected mice decreases. This hormone is the major signaling molecule that maintains muscle. Protective superheroE. Coli is able to activate the IGF-1 signaling pathway and maintain IGF-1 at a positive bacterial level, thus ensuring muscle tissue stability despite infection.
It is unclear whether such superhero bacteria also exist in the human body and whether such superhero bacteria can be used to treat human infections is unclear. Although there are still many problems that need to be explained, however, the use of super-hero bacteria to inhibit bacterial pathogen infection on the body damage, rather than to kill the bacteria itself, is a new idea for the treatment of bacterial infections. Recent studies have found that both PRRSV and PCV2 can coexist with bacterial biofilm, which means that the bacteria may be the carrier of both bacterial toxins, and due to the bacterial biofilm Protection, so that the role of disinfectants on both bacterial toxins greatly reduced.
Five scientists from Université de Montréal and University of Laval of Canada have shown that PRRSv and PCV2 can coexist with bacterial biofilms and survive in biofilms for some days.
Bacterial cells form a structural cluster
In this study, researchers defined "biofilm" as "a structured polymer matrix spontaneously formed by bacteria that adheres to the surface of an object."
Researchers think this biofilm may play a role in protecting bacterial toxins, the researchers said: We therefore hypothesize that some of the important bacterial strains in pig production may be associated with this biofilm structure, and in this biofilm Under the protection of these bacteria in the environment of pig farms survive a long time.
