The elderly's mycoplasma pneumonia and _'s general knowledge of epidemiology
Pneumonia of mycoplasma is that the acute airway infection that the pneumonia mycoplasma causes accompanies pneumonia. The pneumonia mycoplasma is between virus and bacterium and can grow on culture medium without cell, there is not cell wall that contain RNA and DNA, are produced energy by the supersession, often similar with the L type colony obscuring the two of the bacterium. The mycoplasma, for causing the sick body to already know there are 8 kinds of people's mycoplasma at present of animal's many kinds of diseases, pneumonia prop up original physical stamina cause airway infection only, it very fermented glucose wait for and can produce hemolysin, can dissolve sheep and erythrocyte of guinea pig totally in 24- 48h, can distinguish with other mycoplasma other mycoplasma can be caused and secreted the urine reproductive system to infect, seldom infringe the respiratory tract according to this. The pneumonia mycoplasma does not have symptom infection to often cause upper airway infection but not cause with pneumonia. The domestic and foreign report reveals the pneumonia morbidity of mycoplasma in recent years has the tendency to obviously increase.Epidemiology: Mycoplasma travel in air through the intersection of port and secretion of nose, cause airway infection and light to prevail the intersection of pneumonia and mycoplasma infect, present in the family travelling often in ordinary crowd, with men in order to meet more, can have illness coming on, occur frequently, relate to increasing and keeping in close touch in indoor activity mainly with autumn and winter droplet transmission high in morbidity with children and teenagers from acute issues of the intersection of patient and air while being average annual all. Find the intersection of the elderly and morbidity see, increase too, in the intersection of the elderly and the intersection of community and acquired character pneumonia (CAP) in recent years Account for 20%- 30% in the patient, in 4%- 6% of U.S.A., 8%- 10% of the Japan 3.5% of Germany. The chronic getting obstructive consumptive of old age accompanies and takes place the pneumonia mycoplasma to infect and become one of the acute inducements that breaks out of this disease often, and already there is research that has indicated the chronic pneumonia mycoplasma may have participated in chronic obstructive lung disease (COPD) to infect at present Have illness coming on mechanism. The immune function of old age bows the person who happens pneumonia, the pneumonia mycoplasma belongs to the common pathogenic mycoplasma and often presents and takes the mycoplasma state after infecting too, the elder can have can produce antibodies in patient's body for 5 monthsed, but because non- permanent immunity has already proved that there are persons who have illness coming on for the second time to infect with for a disease the next 4- 10 years. This disease relies mainly on distributing, in the gregarious place (kindergarten, school, military camp, family,etc.) Can prevail regional small and prevail and often demonstrate the periodicity (generally 4- 5 years) ,The intermittence has illness coming on, the characteristic of spreading slowly, can last 1- 2, the morbidity increases by 3- 5 times while prevailing.
