bacteremia

The presence of viable bacteria in the circulating blood. (see sepsis) Epidemiology: - PCV13 vaccines have reduced incidence of bacteremia in young children & shifted the most-commonly isolated pathogens from pneumococcus to E coli, S aureus, & Salmonella [4] Diagnostic criteria: - absence of fever, elevated serum C-reactive protein & criteria for systemic inflammatory response syndrome with negative predictive value of 0.99 [3] - a normal blood WBC count does not rule out bacteremia [2] - shaking chills is a positive predictor of bacteremia - normal food consumption is a negative predictor [5]
