Study of Pseudomonas aeruginosa Resistance to Hibitane and Formalin

The effect of hibitane and formalin was studied against Pseudomonas aeruginosa. Bacterial isolates were taken from respiratory, urinary tracts and wound infections.
The sensitivity percentages were recorded to different concentrations of disinfectants in different time intervals. The study showed that Hibitane has a better effect on this bacterium than Formalin, where the isolates were (70%) sensitive to concentration
(2000 gcm3) of Hibitane after (40) minutes of treatment, while their sensitivity percentage to the same concentration of Formalin was (41.7%) after (60) minutes of treatment. The study also showed that sensitivity percentage increases with the increase of disinfectant concentration and treatment time.
