From the human perspective, one of the significant consequences of a bacterium's ability to pass genetic information along to other cells via conjugation is its link to the widespread incidence of antibiotic resistance. The genes that encode for resistance to a variety of antibiotics like penicillin and tetracycline are commonly found on plasmids. Conjugation is a common mechanism of horizontal gene transfer in bacteria that is instrumental in the spread of antibiotic resistance among bacteria. Most resistance genes are found on mobile genetic elements and primarily spread by conjugation. This movie depicts the basic process of antibiotic resistance spreading through plasmid conjugation, otherwise known as horizontal gene transfer. Two strains of bacteria are grown together for four hours. Conjugation: Two bacteria can pair up and connect through structures in the cell membranes and then transfer DNA from one bacterial cell to another. Transduction: There are viruses called bacteriophages that can infect bacteria. These viruses sometimes bring along genes that they picked up during infection of another bacterium. These genes may then be incorporated into the DNA of the new bacterial host. As shown in the animation, a bacterium can directly transfer genetic material to another bacterium using a structure called a pilus. This cell-to-cell transfer process, called conjugation, helps antibiotic resistance genes spread quickly throughout a bacterial population.

Bacterial conjugation is a sexual mode of genetic transfer in the sense that chromosomal material from two sexually distinct cell types is brought together in a defined and programmed process. However, in bacterial conjugation, the process involves only a portion (usually small) of the genome of one of the cells (the donor) and the complete genome of its sexual partner (the recipient), as opposed to sexual union in most higher organisms, which involves an interaction between the entire set Conjugation is a common mechanism of horizontal gene transfer in bacteria that is instrumental in the spread of antibiotic resistance among bacteria. Most resistance genes are found on mobile genetic elements and primarily spread by conjugation. Attributing bacteria with feature of better adaptability, dispersal of antibiotic resistance genes to minimize effects of antibiotics by various means including horizontal gene transfer (conjugation, transformation, and transduction), Mobile genetic elements (plasmids, transposons, insertion sequences, integrons, and integrative-conjugative elements) and bacterial toxin-antitoxin system led to speedy bloom of antibiotic resistance amongst bacteria. Proficiency of bacteria to obtain Conjugation is therefore an important means by which antibiotic resistance is spread between bacteria. The transferred genes may subsequently be incorporated into the bacterial chromosome, as has happened for instance with resistance to antibiotics such as tetracycline and streptomycin.
