Abstract

Background: The Aim of the study was to determine the sensitivity of different types of bacteria to 30 different types of antibiotics by using Kirby-Bauer Method.
Methods: The study was conducted in December 2021 and January 2022, in Al-Samawah city. Where the study was conducted on 33 patients from both genders suffering from urinary tract infection, urine samples were collected using (First morning specimen), Where the chemical tests were carried out before the process of urine culturing by using petri dishes than bacterial species were isolated and their sensitivity to different antibiotics was determined.
Results: Staphylococcus aureus showed sensitivity to different antibiotics where the most effective antibiotic were Imipenem (100%). E. coli showed sensitivity to Amikacin, Imipenem and Meropenem by (100%). For Proteus mirabilis the most effective antibiotics were Amikacin, Cefotaxime, Ceftriaxone, Imipenem and Meropenem by (100%). For Streptococcus pyogenes the most effective antibiotics were Amikacin, Ciproflaxcine, Doxycycline, Imipenem, Meropenem, Norfloxacin, Rifampicin, Levofloxacin and Tetracycline (100%) and for Staphylococcus epidermidi were Cefepime, Norfloxacin, Nitrofurantoin, Piperacillin, Rifampicin, Gentamycin, Trimethoprim, Tobramycin and Levofloxacin (100%) and for Enterococcus faecalis were Cefotaxime, Ceftriaxone, Imipenem, Rifampicin and Meropenem (100%).
Conclusions: The current study shows Staphylococcus aureus and E. coli to be the most common pathogens in our study, with very high antibiotic sensitivities to Amikacin, Cefotaxime, Ceftriaxone, Imipenem and Meropenem and according to the C&S results.
