There are also societal issues related to microbiology, three of which are: bioterrorism, bacterial contamination and antibiotic resistance. Bioterrorism is the use of biological agents as warfare, bacterial contamination is the lost of stored products due to undesired presence of bacteria, and antibiotic resistance is the acquired ability of pathogens to resist the effects of medical treatments.
