How antibiotic resistance spreads between bacteria


How does antibiotic resistance spread? Antibiotic resistance can also be
acquired from another bacterium therefore resistance can spread between
different bacteria within our body Vertical gene transfer and horizontal gene transfer Horizontal gene transfer can occur
between different species of bacteria when mobile genetic elements are
transferred through: Transformation – uptake a DNA into a bacterium from its surroundings Transduction- transfer of DNA by a bacteriophage virus from one bacterium to another Conjugation – direct transfer of DNA in the form of loops called plasmids between two bacterial cells Vertical gene transfer occurs during reproduction as a genetic material is passed from parent to offspring Antibiotic-resistant bacteria are carried
silently by us and can remain in our body for at least a year Resistant bacteria can spread to others
through person to person contact mainly via our hands or things that we
touch
