Science - Essay ExampleThe results also show that there is a smorgasbord community of methicillin resistant staphylococci on the keyboards since methicillin resistant S. Epidermidis and S. haemolyticus were isolated from the computer keyboards. The investigators then concluded that hitherto though there is low prevalence of methicillin resistant Staphylococcus aureus, their presence, coupled with high volume of merchandise on these bookman computer terminals is a demonstration of higher risk. The public access computers have possible to act as reservoirs for Staphylococcus aureus.The hypothesis in this study was that the prevalence of methicillin resistant Staphylococcus aureus on computer rooms and public access computers was high and the keyboards contains strains implicated in disease outbreaks. The research interrogative was that is there high prevalence of methicillin resistant Staphylococcus aureus on computer keyboards of public access student computer terminals. The depe ndent variable in this study was prevalence rate of methicillin resistant Staphylococcus aureus (MRSA) piece the independent variable was the specimen collected from computer terminals used by the students in secondary and slur secondary school.The dependent variable which is the prevalence of MRSA was controlled by following the standard procedure in the collection, handling, vaccination and isolation of Staphylococcus aureus. In this regard the prevalence rate was only read after the gain and isolation. It is important to note that there could be many bacterial growth from samples collected from computer terminals, however, through the use of selective media, mannitol salt agar (MSA), only Staphylococcus aureus could grow. Specimens that are the independent variables were controlled by ensuring that all specimens were collected from the computer keyboards alone and a standard procedure was used to collect, label, prepare and go along the specimen.The
