About this study

Bacteremia is defined as the presence of bacteria in the blood. They can potentially lead to life-threatening septic shock. Effective probabilistic antibiotic therapy must therefore be initiated immediately after blood cultures have been taken. To diagnose bacteremia, blood culture bottles must first be incubated, which allows bacterial growth and early detection. Then, as soon as the sample is positive, an antibiogram of the incriminated bacterium is carried out by inoculation on MH (Mueller Hinton) medium. This diffusion antibiogram is the reference method and is obtained 24 hours after the vial is positive, i.e. around 48 hours after blood cultures are taken. American recommendations agree that it is crucial to use rapid diagnostic tests to obtain the antibiogram. Antibiotic susceptibility test data can be used to broaden the spectrum of antibiotics in the event of ineffective therapy. They can also be used to reduce the spectrum of broad-spectrum antibiotics. This is part of the proper use of antibiotics and the reduction of multi-resistant bacteria (MRB) or highly resistant bacteria (HRB). Finally, it is also possible to carry out an early oral relay, thus avoiding intravenous infusions and their complications, and potentially reducing hospitalization times. The investigators have evaluated a rapid antibiogram by diffusion on MHR-SIR (Mueller-Hinton Rapid-SIR) medium from the blood culture bottle. The investigators were able to obtain antibiogram results 7 hours afte…
