Abstract:
OBJECTIVE To investigate the nasopharynx carriage status of opportunistic pathogens in non-infectious old people.METHODS The totally of 592 pharyngeal samples from old persons were collected.RESULTS The isolated rates of main opportunistic pathogens were Haemophilus parainfluenzae,Stomatococcus mucilaginosus,Streptococcus pneumoniae and Klebsiella pneumoniaa.The isolated rate of single opportunistic pathogen was 45.8% and that of multiple opportunistic pathogens was 3.9%.The total carriage rate of opportunistic pathogen was 49.7%.The carriage rate of G+ or G-bacteria was 13.2% or 86.8%,respectively.The isolated rates of 2 multiple pathogens,S.pneumoniae and K.pneumoniae were increased with aging.The isolated rate of K.pneumoniae was higher in persons with more than 3 kinds of underlying diseases.CONCLUSIONS Aging,pharyngeal carriaging of S.pneumoniae,H.parainfluenzae,K.pneumoniae,et al and with multiple underlying diseases might be the risk factors for elder people to suffer from infectious respiratory disease.Isolating pharyngeal opportunistic pathogen among non-infection people is necessary and significant for prevention and treatment of infectious respiratory disease.
