Bactec is an automatizated method to detect the presence of bacteria in human blood.
The bood is put on a bottle and is incubated at a certain temperature. The machine is able to detect the growth of bacteria in the bottle and alerts the microbiologist.
The BACTEC cannot identify the bacteria present in blood, therefore the microbiologist makes a culture of the positive bottles.
BACTEC has the advantage that microbiologist only harvests the positive samples of blood, making a quick discard of negative samples with gaining of time and saving costs.

I. INDICATIONSRoutine blood cultures should be performed on any patient in whom there is a suspicion of bacteremia or candidemia.Isolator blood cultures should be performed on any patient suspected of having one of the following:1. Subacute or chronic endocarditis with multiple negative BACTEC system cultures. It is appropriate to use the BACTEC system for the initial workup of endocarditis of any suspected etiology. Isolators should be used after multiple BACTEC cultures are obtained and fail to reveal an etiologic agent (including HACEK).2. Suspected deep fungal infection, such as histoplasmosis, blastomycosis, and coccidioidomycosis. Ordinarily, cultures of other sites, such as tissue biopsy, and in some cases serological tests, are more helpful than blood culture.3. Suspected mycobacteremia, particularly in HIV patients with CD4 counts
