In ordinary circumstances, transduction, conjugation, and transformation involve transfer of DNA between individual bacteria of the same species, but occasionally transfer may occur between individuals of different bacterial species and this may have significant consequences, such as the transfer of antibiotic resistance.In such cases, gene acquisition from other bacteria or the environment is called horizontal gene transfer and may be common under natural conditions.Gene transfer is particularly important in antibiotic resistance as it allows the rapid transfer of resistance genes between different pathogens.
