Pneumonia and mycoplasma pneumonia (mycoplasmal pneumonia)
It is by the pneumonia mycoplasma (Mycoplasma pneumomiae) The airway infection caused, there are pharyngitis, bronchitis and pneumonia. The pneumonia mycoplasma is one of the minimum microorganism growing in having culture medium of cells, average diameter 125- 150um, without cell wall, can grow in containing albumin and agar culture medium of steroid alcohol of blood, 2- the colony takes the form of fried egg 3 weeks later, relatively thick among them, it is low and flat around. Mycoplasma travel in air through mouth, secretion of nose, cause airway infection or little to prevail that send out.
This disease accounts for more than 1/ 3 of non- bacterial pneumonia, or 10% of different pneumonia that the reason guide. Often have illness coming on in autumn. Children and young people are in the majority in the patient, the baby should consider the possibility of pneumonia of mycoplasma while having a quality pneumonia.
Pathological change
Begin from the upper respiratory tract, have congestion, monocyte to soak, spread to bronchus and lung, present a quality pneumonia or patch merging bronchus pneumonia. Get up disease to be slow gradually generally, have weak swallowing, aching, coughing, generating heat, receiving difference, myalgia,etc.. Half the number case has no symptom. The X-ray reveals the infiltration shadows of many kinds of shapes of lung, present segment distribution, march off into political wilderness in order to see more with the lung, some spread outwards near the lung door. Propping up gas pneumonia can be dissipated by oneself in 3- 4 weeks. Children can erupt myringitis and otitis media simultaneously, with blood (acute haemolysis, blood platelet reducing purpura) Or neural ' Neuritis, pleurisy,etc.) around Wait for complication or the intersection of Renaud and phenomenon ' The intersection of four limbs and the intersection of intermittence and pale or cyanosis and sense pain catch a cold) When, then the course of disease is lengthened. Use appropriate antibiotic and lighten symptom, shorten the course of disease until 7- 10 days in early days.
The total number of blood leucocyte around increases normally and slightly, take neutral cells as the core. Getting up after being ill for 2 weeks, about 2/ 3 of the patients condense and collect and test the masculine gender, titrate the result price and is greater than 1: 32,Especially when dripping degree and rising progressively, diagnose value. About half the a patient tests the masculine gender to that the streptococcus MG is agglutinate. Further confirmation that diagnose depend on the intersection of serum and the intersection of China and determination (enzyme unite immunity absorb, test most sensitive of antibody, IgM of mycoplasma, the fluorogenic law of the immunity is specific and strong, it is more practical that the indirect blood congeals the law) . The antigen can use PCR law while measuring, but reagent kit still remains to improve, in order to improve sensitiveness and specificity.
It must be distinguished with viral pneumonia, fungus pneumonia of legion that this disease is light. It is very helpful to differential diagnosis for the pathogen to separate masculine gender and serology and test. Acidophil of blood around is normal, this and acidophil increasing lung is soaked and also distinguish to some extent. Treat first-selected erythromycin 0.3g, 4 times a day, can also use antibiotic of Fourth Ring Road clan.
