[The "mycoplasma pneumoniae" in pathological respiratory processes. Serological disease (author's transl)]

The AA. present the results obtained determining by the F.C. test the antibodies for respiraotry viruses and for Mycoplasma pneumoniae over 1112 patients, of which 742 affected with pathological respiratory processes, during the period 1971-1975. 104 patient have shown a significant correlation between respiratory disease and antibody movement for M. pneumoniae. They have been classified according to their clinical-radiological properties as follows: 38 affected with pneumonia; 37 affected with pleuritis; 29 affected with tracheobronchitis. Particularly interesting is the range of occurrence of the disease: we have noticed a high incidence in the period 1971-1972, followed by an almost complete disappearance of pathological instances in the period 1973-first semester of 1975, and signs of a new recrudescence in the second semester of 1975. These data have been confirmed also by investigations carried out among healthy people. It has also to be pointed out the possibility of family's epidemicity, and the AA. report two epidemic cases under personal observation.
