[ABAC, a closed system: problems and solutions, currency and perspectives]

The ABAC System, as it is currently configured, uses pre-determined panels of antibiotics. This form of presentation is a limit for the use of the large number of new molecules, mainly active on Gram-negative bacteria. Therefore, the introduction of a new disposable, called "Gram-negative bacteria--new molecules" is suggested. Such a device will contain those additional and more widely tested antibiotics. According to recent studies concerning the pathology of Gram-positive organisms and the chemotherapeutic treatment for such pathology, changes in the disposable formulations for staphylococci and streptococci are proposed.
