Anyway, it's not just those. There are the wonderful things such asssssss...
Botulinum toxin[23] Botulinum toxin is one of the deadliest toxins known, and is produced by the bacterium
Clostridium botulinum. Botulism causes death by
respiratory failure and
paralysis.
[24] Furthermore, the toxin is readily available worldwide due to its cosmetic applications in injections
Bubonic plague[25] Plague is a disease caused by the
Yersinia pestis bacterium. Rodents are the normal host of plague, and the disease is transmitted to humans by
flea bites and occasionally by
aerosol in the form of
pneumonic plague.
[26] The disease has a history of use in biological warfare dating back many centuries, and is considered a threat due to its ease of culture and ability to remain in circulation among local rodents for a long period of time. The weaponized threat comes mainly in the form of pneumonic plague (infection by inhalation)
[27] It was the disease that caused the
Black Death in Medieval Europe.
Viral hemorrhagic fevers[28] This includes hemorrhagic fevers caused by members of the family
Filoviridae (
Marburg virus and
Ebola virus), and by the family
Arenaviridae (for example
Lassa virus and
Machupo virus). Ebola virus disease has fatality rates ranging from 50–90%. No cure currently exists, although vaccines are in development. The Soviet Union investigated the use of filoviruses for biological warfare, and the
Aum Shinrikyo group unsuccessfully attempted to obtain cultures of Ebola virus.[

multiple organ failure and
hypovolemic shock. Marburg virus was first discovered in
Marburg, Germany. No treatments currently exist aside from supportive care. The arenaviruses have a somewhat reduced case-fatality rate compared to disease caused by filoviruses, but are more widely distributed, chiefly in central
Africa and
South America.
