Antibiotic Resistance of Staphylococcus aureus Isolated fromNasal Cavity of Patients Hospitalized in IMAM HOSSEIN Hospital,Hashtrud

Background and Aim : Staphylococci are metabolically active can grow on many cultivatedenvironments..They usually have cluster and irregular shape. Staphylococcus aureus is the mainpathogen among the staphylococci causing infections at different organs in humans as well asanimals . It is one of the most important pathogen that prioritised by the World Health Organizaionin ۲۰۱۶.Methods : The aim of this study was to evaluate the antibiotic resistance of Staphylococcus aureusisolates cultured from nasopharyngeal clinical specimens in Imam Hossein Hospital of Hashtrood.Therefore ,۱۸۰ specimens were collected from patients andcultured and subsequently identified bybiochemical testsResults : Based on the result of the study of crop characteristics and biochemical separationtests,۲۵ samples of the test (۱۳.۹%) of staphylococcal aureus infection were reported,of which all۲۵ cases of staphylococcus aureus were coagulase positive.All isolated staphylococcus aureus wasevaluated for antibiotic resistance with antibiotics,vancomycin,erythromycin,ciprofloaxin,clindamycin,cefocytosin,oxacillin,ampicilin,chloramphenicol,amoxicillin clavulanic,penicillin,cefazolin by disc diffusion method.That In accordance withthe CLSI protocolConclusion : The result showed that due to the high antibiotic resistance to some antibiotics suchas ampicilin,penicillin,erythromycin,performing the diffusion method before the ude ofantibiotics,comprehensive research in other areas of the province and the antibiotics andSupplemental experiments such az MIC are recommended.Mean while ,all positive samples werestored in microbial bank of the Infectious Disease Research Center and tropical diseaes.
