【Testing method】
1, read the instructions before testing;
2, take a clean urine cup urine samples (if the kit and urine samples stored in the refrigerator, please return to room temperature 18 ℃ -25 ℃);
3, Remove the test card from the aluminum foil bag, placed on a clean and flat table, with a pipette to absorb some urine samples, add 2-3 drops of sample to the sample hole perpendicular to the sample hole.
4,3-5 minutes to read the results. To ensure the accuracy of the results, do not interpret the results after 5 minutes.

[Interpretation of test results]
1, positive (drug addiction): Only one red quality control line appears in the reaction zone.
2, negative (no drug): in the reaction zone quality control line and reaction line two red lines.
3, invalid: quality control line does not appear in the reaction zone, to be re-tested.

细菌利用IV型分泌系统（type IV secretion systems，T4SS）能够转运毒力因子到真核细胞（如肺炎军团菌）、在细菌之间传递遗传物质，包括抗生素抗性基因在不同细菌之间的传递，促进耐药菌的蔓延。T4SS还可能作为对人体细胞进行遗传修饰的潜在工具。
2014年3月发表在Nature上的一项研究，揭示了细菌IV型分泌的结构和作用机制。科研人员利用电子显微镜重构了大肠杆菌R388接合型质粒（conjugative plasmid）编码的IV型分泌系统。结果表明，细菌T4SS无论是分子结构，还是分泌机制，与其它细菌分泌系统都具有本质区别。细菌IV型分泌系统是由8种蛋白质组装成的一个复杂结构，这个结构约3MDa，贯穿整个细菌膜。T4SS包括两个独立的复合体，一个位于细菌的外膜，另一个位于细菌的内膜。它们通过一个茎状结构穿过胞周质连接起来。胞周质是位于细菌内膜与外膜之间的空间。如此一来，在细胞膜上形成了一个孔状结构，细菌通过这种结构分泌物质。
阐明细菌IV型分泌系统的结构，可以帮助人们设计新的药物来靶向性关闭这个系统，从而阻止抗生素耐药基因在细菌之间传播。考虑到当前细菌耐药性已变得如此普遍，严重威胁着人类健康，这项研究结果将对未来细菌耐药性的研究领域产生巨大的影响。巨型DNA细菌毒在光学显微镜下可见，它们的基因组编码的蛋白质比一些细菌或细胞内寄生的真核生物还多。目前已发现两种截然不同的巨型细菌毒，他们都能感染单细胞原生生物，如阿米巴原虫（Acanthamoeba）。一方面，巨型细菌毒（Megaviridae）具有大的伪二十面体（pseudoicosahedral）衣壳包围着大小以兆为单位、富含腺嘌呤和胸腺嘧啶的基因组；另一方面，zui近发现的潘多拉细菌毒（Pandoraviruses）具有微米级的双耳罐状颗粒和细菌达2.8 MB富含鸟嘌呤和胞嘧啶的基因组。

Bacteria use the type IV secretion systems (T4SS) to transport virulence factors into eukaryotic cells (such as Legionella pneumophila), passing on genetic material between bacteria, including the transmission of antibiotic resistance genes between different bacteria , To promote the spread of resistant bacteria. T4SS may also serve as a potential tool for genetic modification of human cells.
A study published in Nature in March 2014 revealed the structure and mechanism of bacterial type IV secretion. Researchers used electron microscopy to reconstitute a type IV secretion system encoded by the conjugate plasmid of E. coli R388. The results showed that bacterial T4SS, whether it is molecular structure or secretion mechanism, has the essential difference from other bacterial secretion systems. The bacterial type IV secretion system is a complex structure assembled from eight proteins that are about 3 Da in size throughout the bacterial membrane. T4SS consists of two separate complexes, one on the bacterial outer membrane and the other on the bacterial inner membrane. They connect through the periplasm through a stemlike structure. The periplasm is located in the space between the bacterial endometrium and the outer membrane. As a result, a cell-like structure is formed in the cell membrane by which bacteria release the substance.
Clarifying the structure of the bacterial type IV secretion system can help people design new drugs to target this system shut down and thus prevent the spread of antibiotic resistance genes among bacteria. Given the current prevalence of bacterial resistance has become so widespread that it is a serious threat to human health, the results of this study will have a huge impact on the future of bacterial resistance research. Giant DNA bacterial toxins are visible under light microscopy, and their genome encodes more proteins than some bacteria or intracellular parasitic eukaryotes. Two distinct bacterial strains of bacteria have now been discovered, all of which are capable of infecting unicellular protists, such as Acanthamoeba. On the one hand, Megaviridae has a large pseudoicosahedral capsid which encloses genomes of adenine and thymine rich in megapores; on the other hand, the recently discovered Pandora bacteria toxin Pandoraviruses) have micron-sized binocular cans and bacteria up to 2.8 MB of guanine and cytosine-rich genomes.
