The primary mechanism for the transfer of antibiotic resistance genes between bacterial cells is horizontal gene transfer, which can occur via conjugation, transformation, or transduction: 1. Conjugation: Direct transfer of genetic material, typically plasmids carrying resistance genes, between two bacteria through a sex pilus. 2. Transformation: Uptake of free DNA containing resistance genes from the environment. 3. Transduction: Transfer of resistance genes from one bacterium to another via a bacteriophage (virus).
