[Epidemiologic problems of pneumococcal infection].
During the microbiological examination of 314 tentatively healthy donors, residents of Leningrad, Streptococcus pneumoniae was detected in the rhinopharynx of 94 donors (29.9%) in amounts ranging from a few individual microbial cells to 10(6) microbial cells with the mean geometric concentration equal to 3.58 lg. Antipneumococcal antibodies were detected in the blood of 147 donors (46.8%). The occurrence of antipneumococcal antibodies was approximately 2.5 times higher than the average level of carriership, but in most cases the dynamics of immunological reactions changed in the same direction. Considerable monthly and annual fluctuations in the occurrence of pneumococcal carriership and antipneumococcal antibodies, as well as their correlation with the epidemic rises of acute respiratory diseases, influenza and other acute respiratory viral diseases, were established. These data indicate that pneumococcal infection plays a definite role in the epidemic rises of acute respiratory diseases.
