title: [The colonization resistance of the tonsils in healthy and frequently ill children].
abstract: State of colonization resistance was studied in healthy children and those presenting with recurring infectious and inflammatory diseases of the upper respiratory tract. Identification of representatives of tonsil anaerobic and aerobic floras was carried out. Lactic acid bacteria (LAB), alpha-Streptococcus, were present in tonsil flora of healthy children. Pathogenic microorganisms and opportunistic pathogens were recoverable from always ailing children with tonsillitis, with alpha-streptococcus being recoverable very seldom and no decrease in LAB levels being seen. In patients--candidates for tonsillectomy, pathogenic microorganisms were identifiable, with LAB levels decrease by a factor of 10(3-4). The above findings suggest development of dysbacteriosis, decrement of tonsil colonization resistance in always ailing children, which fact is to be considered in designing and implementing therapeutic measures.
