Summary
Pneumonia and mycoplasma pneumonia (mycoplasmal pneumoniae) It is the pneumonia mycoplasma (mycoplasma pneumoniae) Acute airway infection and acute inflammation of the lung caused change. Often there are pharyngitis, bronchitis, pneumonia at the same time. Can cause and prevail, account for 10% of different pneumonia, more than 1/3 of the non- bacterial pneumonia, serious mycoplasma pneumonia can also cause the death. It is more to have illness coming on in autumn and winter.
Cause of disease
Pneumonia mycoplasma is between bacterium and virus,and concurrently it last oxygen at sex, can minimum microorganism of lives independent, size cause the sick body for 200 the intersection of nm. and mycoplasma for the intersection of animal and many kinds of disease, already find 8 kinds of types at present, among them only the pneumonia mycoplasma must cause a disease to people, it is mainly respiratory disease. It is transmitted through air by the mouth, nose secretion, causes distributing and little and popular airway infection, mainly see that finds it also non- rare in the adult now to children and teenagers, more in autumn and winter. There are pharyngitis and bronchitis in the airway infection, minority involve the lung.
Onset mechanism
The pneumonia mycoplasma, until recovering for several weeks, can all find in the secretion of respiratory tract 2-3 days before having illness coming on. It infects through keeping in touch, grows among cover on the cilium, does not invade the lung essence, there is neural amino acid receptor at his cell membrane, can absorb to the surface of leather cell on the host's respiratory tract, inhibit cilium moving and leather cell at destructions from, it further causes local organization to damage to produce and oxidize hydrogen at the same time. Its may have something to do to pathogen or their supersession irritated response of product with patient while being pathogenic. Infect, cause the humoral immunity, has already had antibodies in most adult serum, so seldom have illness coming on.
Pathology changes
Last bronchus pneumonia lung pathological change or among quality pneumonia, bronchitises detailed. Can include and ooze out the liquid in the alveolus on a small quantity, and one, lung consolidation and pulmonary emphysema cooking stove lung can happen. Alveolus wall and interval have neutral cells and monocyte, plasma cell that are soaked. Bronchus mucomembranous cell can have necrosis and loss, and neutral cells are soaked. Pleura can have fibrin ooze out and ooze liquid on a small quantity.
