Objective – This study aimed to analyze the proportion of Staphylococcus aureus and Escherichia coli
from urine samples of catheter-associated urinary tract infections (CA-UTI) patients at the General
Hospital at Province of West Nusa Tenggara. Also measured the pattern of sensitivity to several
antibiotics.
Methods –This study is a descriptive observational with a cross-sectional approach. A total of 60 samples
were used in this study. Bacterial identification was carried out according to standard bacteriological
culture techniques. Furthermore, the antibiotic sensitivity test following the Kirby-Bauer disc diffusion
method using several antibiotics, including amoxycillin (AMP), ciprofloxacin (CIP), ceftriaxone
(CRO), and sulphamethoxazole trimethoprim (SXT).
Results –The results showed that bacteria causing CA-UTI were Staphylococcus aureus (43.33%),
Escherichia coli (21.67%), Staphylococcus epidermidis (10%), Proteus mirabilis (6.67%), Enterobacter
aerogenes (6.67%), Serratica marcescens (5%), Klebsiella sp (3.33%), and Pseudomonas sp (3.33%).
The antibiotic susceptibility test found that 4.58%, 11.25%, 9.16%, and 3% of bacteria were resistant to
amoxycillin, ceftriaxone, ciprofloxacin, and sulphamethoxazole trimethoprim, respectively.
Conclusion –Staphylococcus aureus and Escherichia coli were the most gram-positive and gramnegative
bacteria causing CA-UTI, respectively. The most resistant antibiotic was ciprofloxacin, and
the most sensitive antibiotic is sulphamethoxazole trimethoprim.
