Pneumonia and coccus pneumonia pneumococcal pneumonia_ general knowledge
Pneumonia and coccus pneumonia (pneumococcal pneumonia) It is by coccus of pneumonia or pneumonia streptococcus (streptococcus pneuoncae) Cause, account for and is infected with more than half of pneumonia outside the courtyard. The the intersection of lung and piece or lobe of the lung takes the form of acute inflammation nature consolidation, the patient has symptoms such as shiver with cold, hyperpyrexia, chest aching, coughing and blood phlegm,etc.. Because antibacterial in recent years the employing extensively of the medicine, have the light disease or not typical disease to comparatively see clinically more.
[Cause of disease, having illness coming on in mechanism and pathology ]
The coccus of pneumonia is the blue positive coccus of leather, often in pairs (diplococcus of pneumonia) Or arrange in the shape of chain ' Pneumonia streptococcus) ,Fungus have the intersection of pod and membrane outside the body, pod the intersection of membrane and many the intersection of candy and body have peculiar antigen nature, test, know, have 86 piece inferior type already now according to serum. Adult pathogen belong to for 1-9 and 12 type more, with 3 type virulence being the strongest, and 6, 14, 19, and 23 type in children. These bacteria are the normal fungus group of upper respiratory tract, only started to cause a disease just when immunity is reduced. Bacteremia or infective shock, if the not appropriate treatment in time takes place partly to lack, can cause the death.
The coccus of pneumonia can survive in the dry phlegm for several months; But sunshine penetrate 1h direct, heat to 52 10min, can sterilize, the intersection of charcoal and disinfectant such as being sour also very sensitive to stone.
The onset is regarded winter and early spring as much, this and respiratory tract virus are infected and concerned popularly certainly. The patient is often originally healthy people, old man and infant and pre-school children between twenty and fifty, men more see, most patients have virus of slight upper respiratory tract to infect first, or catch cold in, drunk or general anesthesia history, the respiratory tract defends the function to damage, the bacterium is sucked the lower respiratory tract, breeds in the alveolus. Smoker, getting dull-witted, congestive heart decline and the intersection of chronic disease and patient, prop up inflammation while being slow, bronchiectasis, and immunity defective patient easy to be attacked by the coccus of pneumonia. The coccus of pneumonia does not produce the toxin, no cause primarily to organize necrosis or form the cavity; Pathogenic strength its because of contain the intersection of macromolecule and many the intersection of candy and the intersection of pod and membrane of body to the intersection of invasion and attack and function that organize, cause the alveolus wall edema at first, ooze out leucocyte and erythrocyte rapidly, including fungus to ooze out the liquid to spread to the central part of the lung through the Cohn's hole, even climing and several lung section or whole lobe of the lungs, begin with the periphery of the lung because of pathological change, so the boundary is clear among the leaves, and apt to involve the pleura. Pathology changes congestion one, red liver to change one, gray liver and change one and dissipate one. Lung organize the intersection of congestion and edema, alveolus inner thick liquid ooze out with red, leucocyte soaking, engulf bacteria, then the fibrin oozes out things to dissolve, absorb, the alveolus is inflated again. In fact four pathologic stages have not been absolutely demarcated, on condition that use the antibiotic, such typical pathology has been already rare by stages. The institutional framework of lung has not been damaged more, has not kept the fibrous scar after pathological change was dissipated. The inner fibrin of extremely specific patient's alveolus is absorbed incompletely, even have fibrous cells into to take shape, forming machine pneumonia. Old man, and infant and pre-school children infect can distribute along the bronchus ' Bronchus pneumonia) . If has not used and resisted and caught the department in time, 5% - 10% can erupt empyema simultaneously, 15% - 20% the bacterium enters blood circulation through the chest conduit of lymphatic vessel, forms the lung and is infected with (membrane inflammation, peritonitis, otitis media,etc. in pleurisy, arthritis, pericarditis, heart.
