【科普】肺炎支原体阳性=肺炎?

“我家宝宝发热咳嗽,去医院查出肺炎支原体阳性,是不是得了肺炎?怎么办┎啊?”前两天接到一朋友的电话,电话那端充满担心和手足无措。其实,很多家长会有这种顾虑和疑惑。实际上,肺炎支原体感染不等于患上肺炎,小编觉得有必要给大家作下肺炎支原体的科普,缓解下家长紧张焦虑的情绪。

┥1.什么是肺炎支原体?
ヒ@

支原体是介于细菌和病毒之间的已知能独立生活的ㄦ病原微生物中的最小者。支原体广泛分布自然界,有80余种。肺炎支原体属于支原体的一个类别,因其一端有一种特殊的末端结构,能使支原体粘附于呼吸道粘膜上皮细胞表面,引起肺部感染,所以被称为肺炎支原体。

2.肺炎支原体阳性就一定是肺炎?
¼`肺炎支原体阳性

不一定。别看肺炎支原体名字里有“肺炎”两个字,但和我们通常认知的肺炎无直接关系。两者的关系是,肺炎是指涉及肺部的任何炎症性疾病,不都是肺炎支原体感染所致,很多微生物(如病毒、细菌、真菌、寄♒生虫等等)感染都可以引起肺炎。肺炎支原体可以感染儿童导致肺炎,但不是每肺炎支原体阳性一次都会导致肺炎,研究显示,大概只有3%~10%的支原体感染者发生支原体肺炎。

肺炎支原体感染临床症状轻重不一,大多起病不急,有发热、厌食、咳嗽、畏寒、头痛、咽痛、胸骨下疼痛等症状,以发热和咳嗽为主要表现。体温在37℃-41℃,大多数在39℃左右。主要经飞沫传播,潜伏期2-3周,发病率以青少年最高。

3.肺炎支原体如何检测?
ν⛔☃

1)血清测抗体方法(胶体金,被动凝集,ELISA);

2:)PCR检测;

3)肺炎支原体培养;

4)多媒体镜检。

4.目前我㉻院采用的是以下两种方法:

1⭐)血清测抗体方法(胶体金法):采用血清标本,通过测抗体╖IgM  IgG来检测是否感染肺炎支原体。本法简便快捷,能短时间内出结果。

2肺炎支原体培养法:培养法是确诊支原体感染的唯一方法,是流行病学调查、新方法评价的金标准,也是WHO推荐的支原体实验室诊断方法。培养法采用患者的咽拭子或者痰液用于肺炎支原体的分离培养及临床常用14亇种抗生素的药敏测定。㊨24-48小时培养+鉴定+药敏实验一步到位。能快速为临床提供可靠的诊断及药敏依据。

[Science] Mycoplasma pneumoniae positive = pneumonia My baby has a fever and cough. I went to the hospital to find out that Mycoplasma pneumoniae is positive. Is it pneumonia What should I do I received a call from a friend two days ago. The phone was full of worry and at a loss. In fact, many parents have such concerns and doubts. In fact, Mycoplasma pneumoniae infection does not mean suffering from pneumonia. The editor thinks it is necessary to teach everyone about Mycoplasma pneumoniae to ease the anxiety of parents. 1. What is Mycoplasma pneumoniae Mycoplasma is the smallest of the pathogenic microorganisms known to be able to live independently between bacteria and viruses. Mycoplasma is widely distributed in nature, with more than 80 species. Mycoplasma pneumoniae belongs to a category of mycoplasma. It is called Mycoplasma pneumoniae because it has a special end structure at one end, which can make the mycoplasma adhere to the surface of the epithelial cells of the respiratory mucosa and cause lung infection. 2. If Mycoplasma pneumoniae is positive, it must be pneumonia Mycoplasma pneumoniae is not necessarily positive. Dont look at the word pneumonia in the name of Mycoplasma pneumoniae, but it is not directly related to the pneumonia we usually recognize. The relationship between the two is that pneumonia refers to any infla妹妹atory disease involving the lungs. It is not all caused by Mycoplasma pneumoniae infection. Many microorganisms (such as viruses, bacteria, fungi, parasites, etc.) infection can cause pneumonia. Mycoplasma pneumoniae can infect children and cause pneumonia, but not every time Mycoplasma pneumonia is positive will cause pneumonia. Studies have shown that only about 3% to 10% of mycoplasma-infected people develop mycoplasma pneumonia. The clinical symptoms of Mycoplasma pneumoniae infection vary from severity to severity. Most of them do not have a rapid onset, with fever, anorexia, cough, chills, headache, sore throat, and substernal pain. The main manifestations are fever and cough. Body temperature is 37°C-41°C, most of which are around 39°C. It is mainly spread by droplets, the incubation period is 2-3 weeks, and the incidence rate is highest in adolescents. 3. How to detect Mycoplasma pneumoniae 1) Serum antibody detection method (colloidal gold, passive agglutination, ELISA); 2) PCR detection; 3) Mycoplasma pneumoniae culture; 4) Multimedia microscopy. 4. At present, our hospital uses the following two methods: 1) Serum antibody test method (colloidal gold method): Serum samples are used to detect whether they are infected with Mycoplasma pneumoniae by testing antibody IgM and IgG. This method is simple and quick, and can produce results in a short time. 2) Mycoplasma pneumoniae culture method: The culture method is the only method to diagnose mycoplasma infection, it is the gold standard for epidemiological investigation and evaluation of new methods, and it is also the laboratory diagnostic method for mycoplasma reco妹妹ended by the WHO. The culture method uses the patients throat swab or sputum for the isolation and culture of Mycoplasma pneumoniae and the drug sensitivity determination of 14 co妹妹only used antibiotics in clinical practice. 24-48 hours culture + identification + drug sensitivity test in one step. It can quickly provide reliable diagnosis and drug sensitivity basis for the clinic.
