Yes its very important to check the antimicrobial susceptibilty of each isolate because of the increasing number of MRSA(methicillin resistant staph aureus)strains. Your management would differ with each patient,since penicillin is the drug of choice it can't always be used because it is also associated with hypersensitivity reactions so you also need to check for other alternative drugs,and for MRSA strains you would have to go for high grade antibiotics such as vancomycin.
Plus it also depends whether the bacteria was isolated from in patients(hospital acquired infection),most common source being doctors and nurses themselves.(Staph aureus is a part of normal flora,so the staff are possible carriers of infection)
Therefore timely identification would prevent further infection requiring isolation of that particular source(object/person).
