The informative capacity of various statistic parameters characterizing the ecology of pathogens of purulent processes was studied. Many-years' results of the routine bacteriological tests of the materials from purulent wounds in patients from surgical, traumatological and burn departments served as the study subjects. The frequency, persistence and contamination capacity of the pathogens were investigated. Data on the changes in the frequency parameter with respect to the main pathogens of wound infections in various contingents of patients were collected. In relation to the observation period and contingent of the patients, various microorganisms were found to be permanent, supplementary and casual. The use of the ecological parameters was shown to provide integrated information on the etiological role of the pathogens in the development of purulent processes. The information characterized the microbial properties which should be considered in planning the use of antibacterial drugs and estimating the efficacy of the epidemiological control.

The composition of the causative agents of suppurations, isolated from suppurating wounds of patients hospitalized at different departments of the Sklifosovskii Emergency Aid Institute was studied. The proportion of representatives of different microbial families among more than 18,000 strains of the causative agents of wound infection was estimated. Fluctuations in the amount and structure of the agents were analyzed in different clinics over the period of 1967-1987. Under the conditions of emergency aid hospital Staphylococcus aureus proved to be the most frequent causative agent of suppurative inflammatory processes at different departments. At the same time no tendency towards an increase of the etiological role of any microbial family in the development of wound infections was noted. The incidence of different causative agents of suppurations was found to vary at different departments, depending on their specialization and season. The results of observations on the composition of the causative agents of wound infection may be used for the planning and evaluation of antiepidemic measures.
