Microbial characteristic _ general knowledge of the pneumonia streptococcus
(1) Shape and dyeing
It is dyed for being positive that the leather is blue, the spearhead matches and arranges, without cilias, do not form the gemma (afterbirth) ,A bit poisonous one can form the membrane of pod, form one's haemolysis ring on agar culture medium plateform of blood. This fungus can be produced dissolving enzyme, the body of fungus dissolves and forms the umbilicate colony by oneself 24 hours later. Dissolving enzyme by oneself can be activated by the bile and accelerated bacterium's dissolving. The intersection of pneumonia and the intersection of streptococcus and very fermented the intersection of chrysanthemum and candy, so bile dissolve fungus test and the intersection of chrysanthemum and candy ferment, test, can distinguish the intersection of pneumonia and streptococcus and dissolve the courageous and upright streptococcus while being first type.
(2) The main pathogenic material, with disease
1.Main pathogenic material
( 1) The membrane of pod: The resistance of the pneumonia streptococcus with membrane of pod is strong, resist the phagocytosis, and the main virulence factor.
( 2) Pneumonia streptococcus hemolysin( Or dissolve the pneumonia streptococcus plainly) : Can dissolve the erythrocyte of people, horse, sheep and rabbit, and can activate the classical route of the complement, cause generating heat, inflammation and organization to damage.
( 3) Neural amino acid enzyme and hyaluronnidabe: This 2 enzyme is in the nasopharynx department field planting, reproduction and spreading, having something to do with with the mucous membrane of bronchus with the pneumonia streptococcus.
( 4) Purpura forms the factor: Inject it into the rabbit inside, can make its skin present purple spot, bleed some and viscera bleed.
2.Due to is big leaf pneumonia mainly for disease,secondly bronchitis and meningitises suppurative,etc..
