Bacteria isolated from a furuncle have enterococci by way of what transformation?

Bacteria isolated from a furuncle that contain enterococci could have acquired them through horizontal gene transfer, specifically via conjugation or transformation. Conjugation involves the transfer of genetic material (including antibiotic resistance genes) through direct contact between bacteria, while transformation involves the uptake of free DNA from the environment. In both cases, the genetic material could carry traits that enable the bacteria to survive in the furuncle environment, such as antibiotic resistance.
