Abstract
We present two methods for electroporation for the gram positive bacterium Enterococcus faecalis that can also be used as guidelines for work with other gram positive species. We demonstrate the use and the advantages of this technique for investigating genes, both chromosomal and plasmid-linked, encoding surface structures. Electroporation was used to deliver constructs created on shuttle vectors for insertional inactivation of a chromosomal gene involved in binding substance formation as well as for the expression of Aggregation Substance in strains with different chromosomal backgrounds. The influence of defects in lipoteichoic acid synthesis and the expression of Aggregation Substance on virulence was shown in a rabbit endocarditis model.
