Mycoplasma pneumonia overview _ general knowledge of pneumonia
Has already found 11 kinds of type mycoplasma at present, but that cause human airway infection is mainly pneumonia mycoplasma. Will the intersection of pneumonia and acute pneumonia, companion of airway infection, that mycoplasma cause call SARS once first, this is because the etiology to this disease was not so obvious at that time, have thought by mistake it was the virus that infected. Already clear now, the pneumonia mycoplasma is between bacterium and virus, can seek the minimum microorganism of independent life, it have cell wall is can open device of fungus filtered, can grow, breed at culture medium to have cell, contain RNA and DNA, is produced energy by the supersession.
Pneumonia and mycoplasma pneumonia account for more than 1/3 of the non- bacterial pneumonia, or various reasons cause 10% of pneumonia. Have illness coming on more its autumn and winter, but the seasonal difference is not obvious. Foreign report, 15%- 20% of the non- epidemic pneumonia of acquired character of community is pneumonia and mycoplasma pneumonia, in recent years, the pneumonia mycoplasma infects and has the tendency to increase. The pneumonia mycoplasma is transmitted through air by the mouth, nose secretion, cause distributing or little and popular airway infection, and bronchitis that it is mainly pharyngitis, involve the lung and cause pneumonia partly. Infect and mainly see to children and young people (account for 71%) ,Crowd's intensive place is (such as army, school) The infection rate is high.
Incubation period when the pneumonia mycoplasma is infected is 14- 21 days, the disease is slow that most patients get up, 1/3- 1/2 have no symptom. Usually appear in forms such as pharyngitis, trachea, bronchitis, pneumonia, ear myringitis,etc., among them pneumonia is the most serious. The emergence frequency of symptom is to cough, generate heat, be weak, fear cold, has a headache, muscles or arthralgia, swallowing aching, suppuration phlegm, ear to ache etc., some patients have sense symptom similarly, the chest aches rarely, half the number patient can hear and do the wet rale. Pneumonia and mycoplasma pneumonia condition are generally relatively light, a few patients are relatively heavy, but seldom die. It features heat step back, cough and the intersection of lung and rale disappear slow, can lengthen to about 6 week, parallel to dissipation of the X-ray sign more. Lung abscess, enlargement of lymph nodes of lung door, mediastinal lump,etc. can happen to a few patients. The lung X-ray displays the diversification, the characteristic is proportional to physical sign more, namely clinical manifestation is light and X-ray examination finds that more soak the focus, the lung shade disappears to 2- 3 weeks very long, minority can lengthen until 4- 6 weeks.
