Abstract

Besides Staphylococcus aureus, other Gram-positive bacteria have become multidrug-resistant and cause therapeutic problems, particularly amongst hospitalised patients. The acquisition of vancomycin resistance by strains of Enterococcus faecium and Enterococcus faecalis is of particular concern and has resulted in treatment failures. Some of the infections caused by these bacteria do respond to treatment with new antibiotics that have been released in the last few years, however more options are required as not all enterococci are inherently susceptible and resistance is beginning to emerge amongst those that were susceptible. Resistance to commonly used antibiotics is also emerging in Streptococcus spp., particularly to the tetracyclines and macrolides. In both genera, multiresistant strains spread between patients and between hospitals. In the laboratory, these bacteria show considerable susceptibility to tigecycline, with little propensity to develop resistance, indicating that tigecycline could assume an important role in controlling infections caused by these Gram-positive bacteria.
