Abstract:
Objective To investigate the bacteria distribution and drug resistance of lower respairory tract infection of re‐spairtory wards .Methods Sputum from patients with low respiratory tract infection was collected ,K‐B methods and minimun in‐hibitory concentration were used to make distribution and antibiotic resisitance .Results Five hundred and twenty‐nine strains were isolated ,of which gram negative organisms accounted for 416(78 .8% ) ,and gram positive organisms accounted for 88(16 .6% ) ,and fungi accounted for 25(4 .7% ) .In whtich ,the pseudomoas aeruginosa(25 .0% )and acinetobacter baumannii(13 .0% )accounted for the first and second one .Pseudomoas aeruginosa showed varying degrees of resistance to most commomly used antibacterials ,but there were still some alternatives .Acinetobacter baumannii had higher resistance to most commomly used antibacterial ,except for cefoperazone sulbactam .Cefoperazone sulbactam showed high susceptibility to most gram negative organisms and gram positive or‐ganisms .Conclusion In the respiratory wards ,gram negative organisms were predominant in low respiratory tract infection .Pseud‐omoas aeruginosa and acinetobacter baumannii play a main role .The later is resistant to most commonly used antibacterials and the former showes high resisitance except for a few antibacterials .
