Role of pseudomonas aeruginosa and klebsiella pneumoniae in nosocomial infections and their susceptibility to antibiotics and disinfectants

ABSTRACT

This study was conducted on 238 patients. Pseudomonas aeruginosa and Klebsiella pneumonia played a major role in the nosocomial infections. On studying the suspected sources for nosocomial infections, wall and floor, followed by medical staff were the most possible sources for nosocomial infections with P. Aeruginosa, while air, followed by medical staff were the suspected sources for K. Pneumoniae. Fourteen antibiotics were tested on clinical and control isolates of bacteria showing that the most effective antibiotic against P. Aeruginosa was amikacin, followed by aztreonam and ceftazidime, while ofloxacin and ciprofloxacin were the most effective antibiotics against K. pneumoniae. Alkaline glutaraldehyde and povidone-iodine disinfectants were tested for their minimum inhibitory concentration
