Catheter swab samples were taken from newly removed urinary catheters of thirty-five (35) patients of Gregorio T. Lluch Hospital (GTLMH) from four departments namely, Surgery, OB-GYNE, Medicine and Out Patient Department.

Colonial, morphological and biochemical test were done to identify bacteria associated to the development of urinary tract infection. Three commonly associated bacterial species that can cause urinary tract infection attributable to the use of indwelling urinary catheters were identified. These were Staphyloccus aureus, Escherichia coli and Pseudomonas aeruginosa. Majority of Staphyloccus aureus and Pseudomonas aeruginosa species were from subjects aged 27-46. Correlation analysis revealed that the gender is significantly associated with the colonizing bacterial strain. Majority of the bacterial isolates were from female respondents were Pseudomonas aeruginosa specieswhile majorityStaphyloccus and Escherichia species were from male subjects. The study also revealed that colonizing bacterial strain is significantly associated with the number of catheterization. Majority of isolates of isolates from subjects who have been catheterized for the first time were Escherichia coli and Pseudomonas aeruginosa whileStaphyloccus aureusisolates were from subjects who have been catheterized for the sixth and seventh time. Correlation analysis also revealed that the number of days the urinary catheter is in place is significantly associated with species of colonizing bacteria. Bacterial isolates from subjects whose catheters were in place for three and six days were mostly Escherichia coliwhile isolates from subject whose catheters were in place for seven and four days were dominantly Pseudomonas aeruginosa.
