Molecular tools for the characterisation of antibiotic-resistant bacteria.
This review will discuss a number of molecular tools which are currently used as well as some innovative approaches for the characterisation of antibiotic-resistant bacterial strains. Various methods involved in the detection and characterisation of genes and mutations associated with antibiotic resistance and that are used for strain typing as part of epidemiological studies, are described. Furthermore, a few examples are discussed in which the results of both gene and strain characterisation are combined to investigate the underlying mechanism of the spread of antibiotic resistance. Some of the available molecular techniques are heavily supported by the existence of databases on the Internet. These databases either contain a fast growing amount of sequence information or a large number of allelic or fingerprint profiles. The current progress in applied DNA technology and the ongoing projects on the elucidation of the whole genomic sequence of bacterial species have lead and will further lead to the development and application of sophisticated new strategies for the analysis of antibiotic resistant bacterial strains.
