[Antibacterial treatment: perspectives]

The aim of this paper is to search new antibacterial molecules for an efficient therapy. Thus the researches look for new categories of antibacterial molecules that will solve the current and future therapy problems, some of them being already used, others are still evaluated. Among these there are the new antibiotics (streptogramine, oxazolidinone, fluorochinolone and lipopeptides), enzymatic inhibitors (PDF), tubular peptides--nanotubes, cytokines pro- and anti-inflammatory drugs and preparations obtained through genetic engineering (anti-stress molecules, medicines that inhibit the lipid metabolism of the macro-organisms persisting in macrophages or gene mutation pca A, that enables the immunologic recognition of'the tubercle bacillus).
