Plague is a deadly infectious disease, that is caused by the enterobacteria Yersinia pestis. Contrary to popular belief, rats did not directly start the spread of the bubonic plague. It is mainly a disease in the fleas (Xenopsylla cheopis), that infested the rats, making the rats themselves the first victims of the plague. Infection in a human occurs, when a person is bitten by a flea that has been infected by biting a rodent that itself has been infected by the bite of a flea carrying the disease. The bacteria multiply inside the flea, sticking together to form a plug that blocks its stomach and causes it to starve. The flea then bites a host and continues to feed, even though it cannot quell its hunger, and consequently the flea vomits blood tainted with the bacteria back into the bite wound.

Anthrax is a zoonotic (the disease that is normally present in animals and can be transmitted to humans through animals) disease caused by the gram-positive aerobic bacterium called Bacillus anthracis.

• Symptoms depend on the route of infection. They can range from a skin ulcer with a dark scab to difficulty breathing.

• Hence anthrax is a bacterial disease. So, the correct answer is 'Anthrax'.

Anthrax is an infectious disease caused by the bacterium Bacillus anthracis. It usually affects  ruminants like goats, cattle, sheep, horses. However, it is also seen in humans. Symptoms include sore throat, fever, fatigue, muscle aches, nausea, shortness of breath.

A weapon of mass destruction (WMD) is a nuclear, radiological, chemical, biological, or any other weapon that can kill and bring significant harm to numerous humans or cause great damage to human-made structures.

$\rightarrow$ Bioweapon have small size so its easy to carry.

Biowar is the use of highly infectious pathogens, their spores and toxins as agents of biological weapons against humans, crops and animals of enemy country. The agent is kept in a social container that keeps it in active/virulent state during delivery by missile or aircraft. Spray and power are two common forms in which the bioweapon agent is delivered. Potential pathogens for bioweapons agent is delivered. Potential pathogens for bioweapons are Bacillus anthracis, Vibro cholera, small pox virus Pasteurella Yersinia pestis, Botulinum toxin, etc.

Anthrax is treated with the antibiotic ciproflaxacin that is very effective in chronic cases.
