Abstract

This study aimed to isolate bacterial uropathogens from catheterized patients and determine the antibiotics susceptibility patterns of the isolates. Urine samples were collected from 219 catheterized patients and analyzed following standard microbiological methods. Antibiotics susceptibility test was performed on the isolated and identified organisms using the disk diffusion method. A 73.1% of the patients had Catheterized Urinary Tract Infections (CAUTI) and Escherichia coli was the most common organisms accounting for 53.7% of the isolates followed by Pseudomonas aeruginosa (11.9%), Klebsiella pneumonia (11.3%), Proteus mirabilis (8.1%), Staphylococcus aureus (8.1%) and Enterococcus faecalis (6.9%). The prevalence of urinary tract infectious agents was higher in males (75%) and age group of 56-65 was observed to have the highest prevalence of UTI (21.9%). The antibiogram of Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and Proteus mirabilis showed that they were sensitive to Netillin (76.9%) and Levofloxacin (76.9%) while showing varying resistances to Amoxyclav (94.7%), Ceftriaxone (94.7%), Ofloxacin (73.7%), Tetracycline (88.9%) and Cotrimoxazole (100%). Staphylococcus aureus were resistant to Amoxyclav (100%), Cloxacillin (92.3%) and Cotrimoxazole (84.6%) while Enterococcus faecalis were resistant to Cloxacillin (90.9%), Amoxyclav (81.8%) and Cotrimoxazole (72.7%). A large percentage (83.7%) of the isolates had MAR Index > than the critical value of 0.2.
