Description

There are several so-called organ defense systems in the upper respiratory tract, where microbes can enter from the outside. Recently, the role of the normal flora of the upper respiratory tract in fighting infection has attracted attention. In the present paper, we studied the normal bacterial flora of the palatine tonsil, the posterior pharyngeal wall, the larynx and the nasal cavity of patients who were free from otolaryngological disease ranging in age from newborn to 84 years. We examined the acquisition and changes in normal bacterial flora at those sites. We found that the normal flora of α-streptococcus, lactococcus, and micrococcus started to develop 3 and 6 hours after birth in the neonatal palatine tonsil and posterior pharyngeal wall, respectively, and was detected 24 hours after birth in all cases. We did not isolated any anaerobes from the neonatal palatine tonsil and posterior pharyngeal wall until 5 days after birth. The detected ratios of Grampositive bacteria and Gram- negative bacteria decreased with aging. The detected ratio of anaerobes increased with advancing age. The bacteria isolated from the palatine tonsil, the posterior pharyngeal wall and larynx were simiar.
