[Investigation of pathogenic bacteria for pulmonary infections and their drug resistance in neurological intensive care unit].
OBJECTIVE
To investigate the pathogenic bacterial spectrum responsible for pulmonary infections and their drug resistance in patients admitted to neurological care unit.


METHODS
Sputum specimens were obtained from patients who developed pulmonary infections in neurological intensive care unit between January, 2001 and June, 2002 for bacterial culture and isolation. K-B paper disc method was employed for determination of the drug sensitivity of the bacterial isolates.


RESULTS
In the 207 strains obtained from the patients, the majority (68.51%) were Gram-negative and 30.91/ Gram-positive bacteria, with fungi detected in one case (0.48%). The major pathogenic bacteria for pulmonary infection were, in the order of frequency, Staphylococcus aureus(14.49%), Pseudomonas aeruginosa (14.49%), Klebsiella pneumoniae (8.7%), Enterobacter cloacae (6.76%), and Enterobacter aerogenes (6.28%). Drug sensitivity tests showed increased drug resistance of the bacteria, but Staphylococcus aureus still remained sensitive to vancomycin and most of the Gram-negative bacillus sensitive to imipenem.


CONCLUSIONS
The major pathogenic bacteria causing pulmonary infections in neurological intensive care unit are Staphylococcus aureus and Pseudomonas aeruginosa, and their drug resistance is obviously increased, suggesting the necessity of strengthening bacterial surveillance and more adequate clinical use of antibiotics.
