A bacteriological study on urinary tract infections associated with catheterization of hospitalized patients

Abstract EN

The present study aimed to compare between types and percentages of bacterial isolates from urine samples of hospitalized patients who suffer from urinary tract problems and need to use different catheter methods.

There were high significant differences (P ≥ 0.05) in bacterial isolation percentages before and after catheter using in urithral and external ( condom) catheter methods, the results showed 77 (75.4%) of examining urine culture had no bacterial growth and 25 (24.6%) of them were positive before urinary catheter used, included different types of bacteria which were mostly E.

coli, Proteus sp., Coagulase negative Staphylococci(CONS), S.

aureus, Klebsiella sp., Pseudomonas aeruginosa and Streptococcus faecalis with variable percentages were 8 (7.8%), 7 (6.8%), 4 (3.9%), 2 (1.96%), 2 (1.96) and 1 (.98%) for last two types respectively, while all urine culture examination give positive results 102 (100%) after a period of catheter used for the same patients, The same bacterial species were isolated as following ; (CONS), Proteus sp., E.

coli, S.

aureus and Klebsiella sp.

formed highest rates of isolation in urinary tract infections associated with catheterization ranged 24 (23.52%), 23 (22.54%), 15 (14.7%) and 10 (9.8%) to each of the last two types respectively.

It was also possible to isolate same species with the Enterobacter, Citrobacter and Streptococcus faecalis about 5 (9.8%) for two former and 4 (7.8%) respectively in direct bladder catheter method and not isolate it in other methods.

Also the study shows the common bacterial species under experiment could resist to used antibiotics, especially the bacteria which isolated after the urinary catheterization, and the most resistant types were Pseudomonas aeroginosa and S.

aureus followed by E.

coli.
