Title: "Predictors of Mortality in Staphylococcus Aureus Bacteremia" Comment: Aureus species should be written with small letters aureus

Abstract Comment: absence of the abstract in the PDF version Comment: There is no list of abbreviations.

Introduction 1-" taphylococcus aureus bacteremia (SAB) is a common and important infection. The exact incidence of SAB is difficult to ascertain, as prospective population-based surveillance studies are infrequently performed." Comment: the references not ordered
Comment: Introduction very long and have a lot of items 2-"table 1 Summary of studies that have examined the impact of age on mortality in cases of Staphylococcus aureus bacteremia" Comment: a column of authors should be included in Table 1 . 3-" Fig 1Impact of age on overall 30-day mortality from Staphylococcus aureus bacteremia. Percentages of patients who succumbed at 30 days following an episode of Staphylococcus aureus bacteremia are stratified by 10-year age groups.

Comment: Fig 1 should be written as (Figure1) without abbreviation 4-"table 2 All-cause mortality for patients with Staphylococcus aureus bacteremia stratified by the source of infection Comment: Table 2 is not is not interpretative 5-"table 3 Summary of studies that have examined the impact of severity of illness on mortality in Staphylococcus aureus bacteremia " Comment: some of the abbreviations are not illustrated below the table 6-"table 4 Summary of studies that have examined the impact of methicillin resistance on mortality in Staphylococcus aureus bacteremia " Comment: Comment: some of the abbreviations are not illustrated below the table
