本试剂盒主要用于对病菌细菌进行检测，利用快速玻片凝集检测技术，对鲍特菌培养物进行血清学鉴定。本试剂盒仅供科研使用。

一般由百日咳鲍特杆菌（简称百日咳杆菌）感染所引起，同属的支气管败血症鲍特杆菌和副百日咳鲍特杆菌亦可引起。百日咳鲍特杆菌是革兰阴性杆菌，可产生一些致病物质，包括百日咳毒素、气管细胞毒素、腺苷酸环化酶毒素、不耐热毒素以及内毒素等。百日咳毒素可使患者淋巴组织中的淋巴细胞动员到周围血液及气管，细胞毒素可特异性损伤气管纤毛上皮细胞，使之变性、坏死。

2.流行病学

百日咳患者、隐性感染者及带菌者为传染源。潜伏期末到病后2～3周传染性zui强。百日咳经呼吸道飞沫传播，5岁以下小儿易感性zui高，小儿预防注射10年后百日咳感染率与未接种者无区别。

鱼类以上的脊椎动物，在个体生长发育的过程中 髓鞘出现得较晚；而人类于出生时髓鞘已经形成，但可因神经种类的 不同而异。髓鞘的构造，根据偏光显微镜的检查证明，脂质从轴索的 中心向外排列成放射状，蛋白质形成同心圆层，一般推断，蛋白质和 脂肪为相互排成层状的构造。根据x射线衍射，知该层的周期在新鲜材 料上为17—18纳米，在固定的材料上为13—15纳米。进一步用电子显 微镜检查，其同心圆的层状构造及其周期已被确认。即电子密度高的 层和透明层相互排列，前者的宽度为3.5—5纳米，一般认为是蛋白质 层，后者被认为是脂质层。髓鞘的蛋白质主要是白明胶一类的硬蛋白 ，脂质则包括磷脂质（卵磷脂、脑磷脂、鞘磷脂等）、糖脂质和胆固 醇等。髓鞘以许旺氏细胞的细胞膜包裹着轴索，包裹的层数尚不清楚 。髓鞘在一些间断部位缺如，这一部分称郎飞氏绞窄（郎飞氏结）， 两个绞窄之间称结间节（interannular segment）。结间节的长度约 为50-1000微米的范围，长度不一，通常神经纤维越粗则越长。另外 已经清楚，郎飞氏绞窄不仅在周围神经系统，而且在中枢神经系统中 也存在。如果用硝酸银染色，则在横断绞窄部平面变黑的同时，从绞 窄部到两侧轴索也出现许多变黑的横纹，呈十字形，因向称为郎飞氏 （银）十字（Ranvier′s cross）。在髓鞘的许多地方，可以看到有 呈漏斗状的、从鞘外表陷入到轴索的施密特-兰特曼氏切迹 （Schmidt-Lantermann′scleft），和沿此切迹面的螺旋形构造的 高尔基氏漏斗（德Golgischer Trichter），但这些构造只有在伸长 的神经纤维或浸入食盐水中才出现，因此，一般认为它是一种人工产 物。白质是中枢神经系统中主要的三个组成元素之一。在中枢部，由 神经元的轴突或长树突集聚而成。它不含胞体只有神经纤维。白质内 又有各种不同功能的神经束。大脑灰质在外部，白质在内部。 而在脊 髓中，灰质内部，白质包围在灰质外面。

In vertebrates above fish, myelin appears later in the individual's growth and development; while humans have already formed myelin at birth, they may vary with different types of nerves. The structure of myelin sheaths was examined by a polarizing microscope. Lipids were arranged radially outward from the center of the axon, and the proteins formed concentric circles. It is generally assumed that proteins and fats are arranged in layers. According to x-ray diffraction, the period of this layer is known to be 17-18 nanometers on fresh materials and 13-15 nanometers on fixed materials. Further examination with an electron microscope, the concentric layered structure and its cycle have been confirmed. That is, a layer with a high electron density and a transparent layer are aligned with each other. The former has a width of 3.5-5 nm and is generally regarded as a protein layer, and the latter is considered as a lipid layer. Myelin proteins are mainly hard proteins such as gelatin, and lipids include phospholipids (lecithin, cephalin, sphingomyelin, etc.), glycolipids, and cholesterol. Myelin coats the axons with Schwann cell membranes and the number of layers is not known. The myelin sheath is absent at some discontinuities, and this part is called Langer's strangulation (Lang's fly's knot), and an interannular segment between the two strangulations. The length of the internodal joint is in the range of 50-1000 μm, and varies in length. Generally, the thicker the nerve fibers are, the longer the length is. In addition, it is clear that the Langer's strangulation exists not only in the peripheral nervous system but also in the central nervous system. If silver nitrate is used for dyeing, blackening occurs in the plane transverse to the strangulation section, and many darkening stripes appear from the strangulation to the axons on both sides. Cross (Ranvier's cross). In many parts of the myelin sheath, there is a funnel-shaped Schmidt-Lantermann' scleft that falls into the axon from the outer surface of the sheath, and a spiral along this notch. The Golgi funnel (German Golgischer Trichter) was constructed, but these structures only appeared in elongated nerve fibers or were immersed in saline, so it is generally considered an artifact. White matter is one of the three major components of the central nervous system. In the central region, axons or long dendrites of neurons accumulate. It does not contain only neurons in the cell body. White matter has nerve bundles of various functions. The gray matter is on the outside and the white matter is on the inside. In the spinal cord, inside the gray matter, white matter surrounds the gray matter.
