Abstract
One of the most significant harmful microorganisms is Staphylococcus aureus. Due to the rise in the resistance of this bacteria to antibiotics and the lengthening of hospitalized patients' treatments, one of the causes of infection and mortality among patients hospitalized in special care units of hospitals. In this cross-sectional descriptive study, samples of 113 S. aureus isolates were taken from patients who had spent 4 months in the special care units of Ahvaz teaching hospitals. These samples were then tested using antibiograms for oxacillin, cefoxitin, linezolid, ciprofloxacin, clindamycin, trimethoprim sulfamethoxazole, vancomycin, penicillin, and Antibiotic resistance was discovered, and the findings were evaluated against those of previous investigations. 51 (57.63%) of the 113 patient-isolated samples were female, while 62 (70.1%) were male. The oldest person was 89 years old and the youngest was 4 years old. Linezolid antibiotics were effective against every tested strain, although they were ineffective against 6 tested strains (6.31%), 4 tested strains (3.54%), and 1 tested strain (88%) isolated from wound urine. Vancomycin-resistant bacteria have been found. The findings of this study demonstrate that hospital strains of S. aureus are resistant to many antibiotics. Therefore, it is important to avoid prescribing and using available antibiotics unnecessarily. It is also advised to look at the evolution of antibiotic resistance in hospital infection management in order to stop the development of resistance to these antibiotics.
