Positive blood-culture to bacteremia by enterobacteria	Microbiological studies	Patients with positive blood-culture to bacteremia by enterobacteria

Primary Outcome Measures

Name	Time	Method
Correlation between the MIC of different antibiotics and the prognosis in patients with bacteremia.	36 months	Study the correlation between the minimum inhibitory concentration (MIC) of cefotaxime, ceftriaxone, cefepime, amoxicillin/clavulanic, piperacillin/tazobactam, ertapenem, imipenem, meropenem, ciprofloxacin and levofloxacin and the prognosis in patients with bacteremia by enterobacteria, with or without mechanisms of resistance
Correlation between CLSI and EUCAST cut-off points, FC/FD cut-off points with clinical prognosis and of the microbiological response in patients with bacteremia.	36 months	Determine if the CLSI and EUCAST (European Committee on Antimicrobial Susceptibility Testing) sensitive clinical cut-off points, as well as the suggested by pharmacokinetic and pharmacodynamic studies (FC/FD) are properly independent predictors of clinical prognosis and of the microbiological response in patients with bacteremia
Correlation between piperacillin/tazobactam serum concentrations and clinical prognosis	36 months	Evaluate if piperacillin/tazobactam serum concentrations are correlated with prognosis based on clinical sensitive cut-off points by CLSI and EUCAST
