cause pathogen to burst
not effective against viruses

4. Antibiotic resistance can cause medicines
to become ineffective.

A copy of the plasmid is transferred through conjugation.
Resistance is quickly spread through many bacteria.
Caused by:
misuse or overuse of
antibiotics
Use in livestock feed
Antibacterial soaps
