Evaluation of Methicillin and Vancomycin Resistant Staphylococcus Aureus among The Patients with Chest Infections
Abstract
The aim of this study was to evaluate methicillin and vancomycin resistant Staphylococcus aureus among the patients with chest infections, in Al-Shaab hospital during the period from May to June 2011. In this study 147 sputum samples were collected from patients, from all ages, suffering from chest infection, who were previously investigated by physician. All the samples were subjected to bacteriological examination in order to isolate Staphylococcus aureus. Then the samples were subjected to antimicrobial sensitivity tests by disc diffusion method, using Methicillin and Vancomycin discs. Various strains of Staphylococcus aureus were isolated as causative agents, 25(17%). On subjecting to antimicrobial sensitivity these strains gave different results about 3(12%) were found resistant to Methicillin and all the strains were susceptible to vancomycin. The study showed that the prevalence of the MRSA was greater in ages between 15 to 30 years and more in males than in females.
