Horizontal Genetic Exchange, Evolution, and Spread of Antibiotic Resistance in Bacteria
1 Aug 1998
Abstract excerpt
Some transformable bacteria have acquired target-mediated antibiotic resistance by horizontal genetic exchange of fragments of chromosomal genes. The resistant strains express variants of the antibiotic target that are metabolically active but exhibit a lowered affinity for the antibiotic. The alleles encoding these resistant proteins are mosaics comprising DNA derived from the host and other bacteria, often...
