Pneumonia and mycoplasma pneumonia sum up _'s general knowledge
Pneumonia mycoplasma (mycoplasma pneumoniae) Sucked people to infect by the respiratory tract by the droplets, children and teenagers exchange the sense. Increase in recent years pneumonia mycoplasma pneumonia,at CAP pathogen form than in account for 15%-20% or getting higher. Pathological change often involves the angry way first, the trachea, bronchus and thin bronchitis emerge, the mucomembranous congestion edema, is in charge of and full of neutral cells and macrophages. Can also soak lymphocytes and the plasma cell around mucomembranous lower floor and bronchus. Inflammation prolong and alveolus cause relying mainly on monocyte alveolus ooze out, can produce cooking stove the intersection of lung and piece, the intersection of lung and consolidation, getting in weight to can be seen filling the air alveolus necrosis. Most patients present pharyngitis, the trachea first bronchitis,etc. after infecting the mycoplasma, about 10% of the patients produced pneumonia. Mycoplasma pneumonia and getting clinical disease are relatively slow.
Generate heat generally at 38 about, even hyperpyrexia. The dry cough stresses symptom most for this disease, present the popping drama to cough, see the mucus or mucus suppuration phlegm sometimes, have blood of phlegm occasionally. There is little physical sign of chest, can hear sometimes and doing, wet sound. The X-ray behaves variously, present a quality change in early days and can present bronchus pneumonia subsequently, or the fan-shaped shade spread to the lung field in week from the lung door, the enlargement of lymph nodes of accidental lung door and a few thoraxes accumulate the liquid. Mycoplasma the intersection of pneumonia and condition present benign process generally, generate heat sustainable 3 weeks such as l-, it can be as long as 6 weeks to cough. A few cases present serious disease and pneumonia or present complication outside the lung, can cause death. Diagnose and depend on the respiratory tract sample and train, but technology expects relatively much, use 3 weeks, clinical and impracticable. The deserted agglutinate test of blood is greater than or equal to l: 40 or serum antibody test can be regarded as clinical diagnosis and consulted. It is relatively tall that PCR measures mycoplasma DNA sensitiveness and specificity, can be used for diagnosing in early days, but not sanctioned being used in clinic yet. The pneumonia mycoplasma is insensitive to amide in one, and big intra-annular esters, tetracycline or quinoline promise ketone drug therapy is effective, 10- 14 days of course of treatment.
