Pathogen that can be weaponized
harmful biological agents

Biological weapons are pathogens used as weapons. In addition to these living or replicating pathogens, toxins and biotoxins are also included among the bio agents. More than 1,200 different kinds of potentially weaponizable bio agents have been described and studied to date. Some biological agents have the ability to adversely affect human health in a variety of ways, ranging from relatively mild allergic reactions to serious medical conditions, including serious injury, as well as serious or permanent disability or even death. Many of these organisms are ubiquitous in the natural environment where they are found in water, soil, plants, or animals. Bio agents may be amenable to "weaponization" to render them easier to deploy or disseminate. Genetic modification may enhance their incapacitating or lethal properties, or render them impervious to conventional treatments or preventives. Since many bio agents reproduce rapidly and require minimal resources for propagation, they are also a potential danger in a wide variety of occupational settings.

Since 1997, United States law has declared a list of bio agents designated by the U. S. Department of Health and Human Services or the U. S. Department of Agriculture that have the "potential to pose a severe threat to public health and safety" to be officially defined as "select agents" and possession or transportation of them are tightly controlled as such. Select agents are divided into "HHS select agents and toxins", "USDA select agents and toxins" and "Overlap select agents and toxins".

The U. S. Centers for Disease Control and Prevention (CDC) breaks biological agents into three categories: Category A, Category B, and Category C. Category A agents pose the greatest threat to the U. S. criteria for being a Category "A" agent include high rates of morbidity and mortality; ease of dissemination and communicability; ability to cause a public panic; and special action required by public health officials to respond. Category A agents include anthrax, botulism, plague, smallpox, and viral hemorrhagic fevers.

The following pathogens and toxins were weaponized by one nation or another at some time. NATO abbreviations are included where applicable.

Toxin Source of toxin (military symbol)AbrinRosary pea (Abrus precatorius) Botulinum toxins (A through G) Clostridium botulinum bacteria or spores, and several other Clostridial species.

While the history of biological weapons use goes back more than six centuries to the siege of Caffa in 1346, international restrictions on biological weapons began only with the 1925 Geneva Protocol, which prohibits the use but not the possession or development of chemical and biological weapons in international armed conflicts. Upon ratification of the Geneva Protocol, several countries made reservations regarding its applicability and use in retaliation. Due to these reservations, it was in practice a "no first use" agreement only. The 1972 Biological Weapons Convention (BWC) supplements the Geneva Protocol by prohibiting the development, production, acquisition, transfer, stockpiling and use of biological weapons. Having entered into force on 26 March 1975, the BWC was the first multilateral disarmament treaty to ban the production of an entire category of weapons of mass destruction. The BWC is considered to have established a strong global norm against biological weapons, which is reflected in the treaty's preamble, stating that the use of biological weapons would be "repugnant to the conscience of mankind". However, the BWC's effectiveness has been limited due to insufficient institutional support and the absence of any formal verification regime to monitor compliance. In 1985, the Australia Group was established, a multilateral export control regime of 43 countries aiming to prevent the proliferation of chemical and biological weapons. In 2004, the United Nations Security Council passed Resolution 1540, which obligates all UN Member States to develop and enforce appropriate legal and regulatory measures against the proliferation of chemical, biological, radiological, and nuclear weapons and their means of delivery, in particular, to prevent the spread of weapons of mass destruction to non state actors.
