A bioterrorism attack is the deliberate release of viruses, bacteria, or other germs (agents) used to cause illness or death in people, animals, or plants. These agents are typically found in nature, but it is possible that they could be changed to increase their ability to cause disease, make them resistant to current medicines, or to increase their ability to be spread into the environment. Biological agents can be spread through the air, through water, or in food. Biological weapons (BWs) are the terrorist's perfect weapon; they are relatively easy to make, difficult to detect, and a significant threat of morbidity and mortality. The aim of this review is to clarify the different pathogens and toxins that can be converted to bioweapons and can be used to commit bioterrorism and biocrime in addition to focus light on the new subfield of forensics-microbial forensics. and the role of ethics as a Weapon to Counter Bioterrorism.
