Abstract:
OBJECTIVE To investigate the pathogen spectrum distribution in respiratory tract infection during the past twelve years.METHODS The method was retrospectively analyzed.RESULTS A total of 7596 strains in(clinical) specimens were isolated.It showed that the isolating rate of Gram positive cocci,Gram negative bacilli and fungis was 34.56%,48.62% and 10.10%,respectively.The isolating rate of Gram positive cocci was 25.96% between Jan 1991 to Dec 1996,the most commonly isolated bacteria of which were Staphylococcus(aureus),Streptococcus pneumoniae and ?-hemolytic streptococci,with isolating rates being 6.85%,4.84 % and(4.26%),(respectively);the isolating rate of Gram negative bacilli was 63.33%,the most commonly isolated bacteria of which were Pseudomonas aeruginosa,Escherichia coli and Klebsiella pneumoniae,with isolating rates being(8.46%),7.97% and 7.09%.The isolating rate of Gram positive cocci was 37.91% between Jan 1997 to Dec 2002,the most commonly isolated bacteria of which were S.aureus,?-hemolytic streptococci and Str.pneumoniae,with isolating rates being 10.28%,7.02% and 6.68%,respectively;the isolating rate of Gram negative bacilli was 47.64%,the most commonly isolated bacteria of which were P.(aeruginosa),E.coli and K.pneumoniae,with isolating rates being 8.19%,7.07% and 5.21%,respectively.The isolating rate of fungi was 6.06% and 11.43%,respectively during the two stages,the most commonly pathogen of which was Candida albicans.(CONCLUSIONS) The pathogen spectrum distribution in respiratory tract infection during the past twelve years has changed significantly.The isolating rate of Gram positive cocci and fungi,respectively is gradually increasing,but that of Gram negative bacilli is decreasing.
