本試劑盒主要用于對病菌細菌進行檢測，利用快速玻片凝集檢測技術(shù)，對鮑特菌培養(yǎng)物進行血清學鑒定。本試劑盒僅供科研使用。

一般由百日咳鮑特桿菌（簡稱百日咳桿菌）感染所引起，同屬的支氣管敗血癥鮑特桿菌和副百日咳鮑特桿菌亦可引起。百日咳鮑特桿菌是革蘭陰性桿菌，可產(chǎn)生一些致病物質(zhì)，包括百日咳毒素、氣管細胞毒素、腺苷酸環(huán)化酶毒素、不耐熱毒素以及內(nèi)毒素等。百日咳毒素可使患者淋巴組織中的淋巴細胞動員到周圍血液及氣管，細胞毒素可特異性損傷氣管纖毛上皮細胞，使之變性、壞死。

2.流行病學

百日咳患者、隱性感染者及帶菌者為傳染源。潛伏期末到病后2～3周傳染性zui強。百日咳經(jīng)呼吸道飛沫傳播，5歲以下小兒易感性zui高，小兒預(yù)防注射10年后百日咳感染率與未接種者無區(qū)別。

白質(zhì)是中樞神經(jīng)系統(tǒng)中主要 的三個組成元素之一，與灰質(zhì)、黑質(zhì)并列。大腦剖面中的白質(zhì)組織是 由大量的髓磷脂（脂質(zhì)）組成，在裸視觀察下呈現(xiàn)白色。白質(zhì)由被髓 鞘包覆著的神經(jīng)軸突組成，控制著神經(jīng)元共享的訊號，協(xié)調(diào)腦區(qū)之間 的正常運作。人類到了約二十歲時，白質(zhì)才會在不同腦區(qū)逐漸發(fā)育完 全，而其生長的時機與成熟程度，會影響到學習、自我控制與精神疾 病，例如精神分裂、自閉癥與病態(tài)性說謊，青少年的“年少輕狂”的 原因之一也是由于白質(zhì)未發(fā)育*。神經(jīng)元間軸突傳輸訊息的速度， 有髓鞘絕緣的要比沒有髓鞘的快。寡突細胞制造的脂質(zhì)，會纏繞軸突 10~150層。有許多因子可以刺激髓鞘的形成，例如星狀細胞常會“監(jiān) 聽”軸突傳送的訊號，并將化學訊息送達寡突細胞。脊髓白質(zhì)（white  matter）在灰質(zhì)的外周，可分前索、側(cè)索、秋后索三個部分。其中有 上行1、紅核red nucleus：位于中腦上丘平面的被蓋部，呈圓柱狀。 主要接受來自小腦和大腦皮質(zhì)的傳入纖維，并發(fā)出紅核脊髓束，相互 交叉后到對側(cè)，下行至脊髓。2、黑質(zhì)substantia nigra：位于中腦 被蓋和大腦腳底之間的板狀灰質(zhì)，延伸于中腦全長，可分為背側(cè)的致 密部和腹側(cè)的網(wǎng)狀部。黑質(zhì)的細胞內(nèi)含黑色素，故呈黑色；同時還含 有多巴胺。多巴胺是一種神經(jīng)遞質(zhì)，經(jīng)其傳出纖維釋放到大腦的新紋 狀體，臨床上因黑質(zhì)病變，多巴胺減少，可引起震顫麻痹。3、中縫核 （raphe nuclei）位于腦干中縫附近的狹窄區(qū)域內(nèi)，可分成數(shù)個核團 總稱為中縫核，包含5-羥色胺能神經(jīng)元，其主要功能是產(chǎn)生神經(jīng)元遞 質(zhì)——5-羥色胺。該遞質(zhì)與暴力、憤怒、冒險、攻擊行為有關(guān)。5-羥 色胺神經(jīng)元的激活具有抑制攻擊行為的作用，與鎮(zhèn)痛、睡眠有關(guān)。4、 下橄欖核（inferior olivary nucleus）廣泛接受脊髓全長的上行 投射纖維和腦干感覺性中繼核團的傳入纖維；還接受來自大腦皮質(zhì)、 基底核、中腦紅核和中腦導(dǎo)水管周圍灰質(zhì)的下行投射纖維。
White matter is one of the three main components of the central nervous system, and it is closely associated with gray matter and substantia nigra. The white matter tissue in the brain section is composed of a large amount of myelin (lipid) and appears white under naked vision. The white matter consists of axons sheathed by myelin sheaths, which control the signals shared by neurons and coordinate the normal operation between brain regions. When humans reach about twenty years of age, white matter will gradually develop in different brain areas. The timing and maturity of growth will affect learning, self-control, and mental illness, such as schizophrenia, autism, and morbidity. One of the reasons why teenagers are "young and frivolous" is because white matter is not fully developed. The speed at which axons between neurons transmit messages is more rapid than that without myelination. The lipids produced by oligodendrocytes will wrap around 10 to 150 layers of axons. There are many factors that can stimulate the formation of myelin. For example, slate cells often “listen” to monitor axonal signals and send chemical messages to oligodendrocytes. The white matter on the periphery of gray matter can be divided into three parts: anterior cord, lateral cord, and posterior cord. Among them are the upstream 1 and red core nucleus: the capped part of the midbrain plane, which is cylindrical. It mainly receives afferent fibers from the cerebellum and cerebral cortex and emits a red nucleus spinal bundle that crosses to the opposite side and descends to the spinal cord. 2. Substantia nigra: The plate-like gray matter located between the lid of the midbrain and the sole of the brain. It extends over the entire length of the midbrain and can be divided into the dorsal dense part and the ventral part of the reticular formation. The cells of the substantia nigra contain melanin and are therefore black; they also contain dopamine. Dopamine is a neurotransmitter that is released into the new striatum of the brain through its outgoing fibers. Clinically, because of substantia nigra lesions, dopamine decreases and can cause paralysis of paralysis. 3. Raphe nuclei is located in a narrow region near the midbrain of the brain stem and can be divided into several nuclei. It is called the nucleus raphe magnus and contains serotonergic neurons. Its main function is to produce neurotransmitters. 5- Serotonin. The transmitter is related to violence, anger, adventure, and aggressive behavior. The activation of 5-hydroxytryptamine neurons has the effect of inhibiting aggressive behavior and is associated with analgesia and sleep. 4. Inferior olivary nucleus widely accepts both full-length spinal cord projection fibers and afferent fibers of the brainstem sensory relay nuclei; it also receives afferents from the cerebral cortex, basal ganglia, midbrain red nucleus, and midbrain Downcast projection of grey matter around the water pipe.

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.
