[Multidrug resistance in Klebsiella pneumoniae: multicenter study].

The extensive use of broad spectrum antibiotics, especially the third generation cephalosporins (C3G), was followed by the emergence of newer plasmid mediated betalactamases called extended spectrum betalactamases (ESBLs). To assess the impact of K. pneumoniae resistant to 3GC in Tunisia, this study was conducted in 3 teaching hospitals.
