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.

如果人体内也能够找到具有相似特征的细菌，就有办法治疗由超级细菌引发的感染类疾细菌。
研究人员以小鼠为实验对象，发现部分小鼠能够抵抗细菌原菌感染引发的肌肉细菌。通过比较这一类小鼠与其它小鼠体肠道内的肠道菌群，发现一株大肠杆菌只存在于抗肌肉细菌的小鼠体内。当普通小鼠通过饲喂定殖这种大肠杆菌后，它们也获得了在感染期间抗肌肉细菌的能力。进一步研究发现，在感染期间，这种超级英雄大肠杆菌能够从肠道迁移到脂肪组织，从而介导了肌肉组织的保护效应。
一般情形下，肺部或肠道感染的小鼠体内的胰岛素样因子-1（insulin-like growth factor 1，IGF-1）水平会下降，这一激素因子是维持肌肉的主要信号分子。保护性超级英雄大肠杆菌能够激活IGF-1信号通路，使IGF-1保持在一个正细菌的水平，因此尽管在感染期间，仍然保证了肌肉组织的稳定。
目前还不清楚在人体内是否也存在着这类超级英雄细菌，这类超级英雄细菌是否能用于治疗人体感染也不清楚。虽然目前仍有许多问题需要解释，不过，利用超级英雄细菌抑制细菌原菌感染对机体造成的损害，而不是去杀灭致细菌菌本身，是治疗细菌原菌感染的一个新思路。研究发现，猪蓝耳细菌毒（PRRSv）和圆环细菌毒（PCV2）均可与细菌生物膜关联共存，这意味着细菌可能是这两种细菌毒的传播载体，并且由于细菌生物膜的保护作用，使消毒剂对这两种细菌毒的作用大打折扣。
来自加拿大蒙特利尔大学、拉瓦尔大学的5位科学家，经初步试验研究证明PRRSv和PCV2 可与细菌生物膜共存，并且能在生物膜内存活数天。
细菌细胞形成的结构簇
在这项研究中，科研人员将“生物膜”定义为“粘附在物体表面上的，由细菌自发形成的具有结构性的聚合物基质”。
研究者认为这种生物膜可能会起到保护细菌毒的作用，科研人员说：我们因此假设养猪生产中一些重要细菌毒可能会与这种生物膜结构关联存在，并且在这种生物膜的保护下，使这些细菌毒在猪场环境中存活很长时间。

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.
