Objective: To identify the most common UTI-causing bacteria in the study samples and to identify the most culture-sensitive antibiotics.
Methodology: The study was conducted at Adiwahiyah Teaching Hospital in Iraq's mid-Euphrates area from January 15, 2018 to September 2, 2019. The research included 400 Iraqi patients ages 2 to 85 with UTI symptoms.
Results: E. coli was sensitive to imipenem, meropenem, amikacin, and chloramphenicol. Klebsiella pneumoneae was sensitive to amikacin, imipenem, and meropenem. Enterobacter aerogenes was sensitive to imipenem, chloramphenicol, amikacin, and meropenem. Morganella morganii was sensitive to imipenem, meropenem, amikacin, and chloramphenicol. Trimethoprim-sulphamethoxazole, trimethoprim, tetracycline, and doxycycline were effective against Proteus mirabilis. Imipenem and meropenem were effective against Pantoea agglomerans. Amikacin, imipenem, and meropenem were effective against Providencia stuartii. Serratia marcescens was susceptible to trimethoprim-sulphamethoxazole, trimethoprim, amikacin, chloramphenicol, imipenem, and meropenem.
Conclusion: In the current study, in order of frequency, the most frequently isolated bacteria were E. coli, followed by Staph aureus. The study showed that the three best antibiotics for almost all isolated bacteria were imipenem, meropenem and amikacin with very minor exceptions.
