This study included the collection of 554 samples from different clinical sources and cases for patients of different ages, visit the different Diwaniyah hospitals for the period from November 2021 to March 2022. Staphylococcus aureus was investigated. The results showed the yield of 100 isolates of S aureus bacteria, which included 11 isolates from burns, 11 from wounds, 24 from sputum, and 55 from urine. MRSA was investigated using the method of spreading on the agar, and it was 80%, 50% urine, 25% sputum, 13% burns, and 11%wound. An antibiotic assay was done towards MRSA isolates, and the percentages were as follows: Penicillin 100%, Cefoxitin 100%, Moxifloxacin (MFX) 76.2%, Erythromycin 70%, azithromycin 63.7%, levofloxacin 51.5, CLARITHROMYCIN Amikacin 41, 38% 12, Clindamycin 287%, Ofloxacin 41.2%, Tetracycline 36.2%, Doxycycline 31.2%, Rifampin 23.7%, Norfloxacin 18.7%,Trimethoprim 18.7%, Gentamicin 13,3% Trimethoprim-Sulfamethoxazole 12 and Ciprofloxacin and 12% and Nitrofurantoin 10% and Chloramphenicol 6.1%, while the values of the MAR index ranged from 0.75 to 0.05
Staphylococcus aureus, especially resistant to methicillin, is one of the Basic causes of hospital infection, its resistance to antibiotics has constituted a public health problem worldwide, due to the lack of studies related to the examination of sensitivity to antibiotics, especially in methicillin-resistant species in Iraq and in the city of Diwaniyah in particular. Therefore,The current study aimed to find out the prevalence rate antibiotic resistance in these bacteria isolated from different clinical sources in some hospitals in the governorate. During the research, 554 clinical samples (221 urine samples, 178 sputum samples, 100 burns samples and 55 injuries) for the period from the 11th of 2021 to the 3rd of 2022. Relying on the results of in vitro culture and conventional microscopic and biochemical assays, 100 isolates of Staphylococcus aureus were identified, using the cefoxetine disc spread method, as 80 isolates belong to MRSA. The results of the antibiotic susceptibility test were examined retrospectively. Using the method (Kirby Bauer) using 20 antibiotics used in the current study and it was found that (78%) Of these bacteria were multidrug resistant (MDR).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
