[The ecological communality of obligate anaerobic and aerobic causative agents of suppurative processes].

The composition of aerobic-anaerobic associations in peritonitis and mediastinitis has been found to correspond to the normal microflora of the biotope organ whose lesion leads to the development of the pathological process. As shown with the use of Jacquard's coefficient, in peritonitis the highest degree of ecological similarity is observed among bacteroids and enterobacteria (45.8%) and in mediastinitis and phlegmons, among bacteroids and staphylococci (45.0% and 45.4% respectively). The results of the study of symbiotic relationships among bacteria in the focus of inflammation may be used in the study of the pathogenesis of mixed infections.
