World's 10 scariest bio-weapons

New Delhi: At all times people have tried to use every opportunity to find a new viable option destroying each other. In this way, we even built some of the most serious bio weapons.This list compiles ten of the most deadly and infectious bio weapons that are stored in labs. From Anthrax to Smallpox to Ebola. Some are even created by mixing existing ones to form a new variant such as Ebolapox which combines the fatality of Ebola with the rapid spread of Smallpox.1. Bubonic Plague Bubonic plague is a zoonotic disease, circulating mainly in fleas on small rodents, and is one of three types of bacterial infections caused by Yersinia pestis (formerly known as Pasteurella pestis), that belongs to the family Enterobacteriaceae. Without treatment, the bubonic plague kills about two thirds of infected humans within four days. 2. Botulinum Toxin Botulinum toxin is a protein and neurotoxin produced by the bacterium Clostridium botulinum. It is the most acutely lethal toxin known, with an estimated human median lethal dose (LD-50) of 1.3–2.1 ng/kg intravenously or intramuscularly and 10–13 ng/kg when inhaled. Botulinum toxin (BTX) can cause botulism, a serious and life-threatening illness in humans and animals. 3. Rinderpest Rinderpest is caused by a virus that is closely related to the measles virus. The virus affects cattle and other ruminant animals, such as goats, buffalos and giraffes. The disease is highly contagious, causes fever, loss of appetite, dysentery and inflammation of the mucous membranes. The symptoms persist for about 6-10 days, then the animal usually dies by dehydration. 4. Blackpox There are two clinical forms of the smallpox virus, variola major and variola minor. Variola major causes severe disease by producing characteristic large pustules, or pocks, in the skin, kidneys, lungs, intestines and other organs such as the brain. A rare hemorrhagic form of smallpox causes blistering and bleeding inside the body, in the stomach and intestines and bleed-out occurs similar to what is seen with Ebola virus. The skin appears to shrivel and blacken, hence the name blackpox. 5. Rice Blast A large number of bacteria, viruses and toxins pose a serious threat to humans, but many organisms prefer other prey: to grow food. Getting rid of cultures from their enemies - it is an important task for a person with no food because people will panic, disorder and, ultimately, death will come. 6. Cholera Cholera is an infection of the small intestine caused by the bacterium Vibrio cholerae. The main symptoms are watery diarrhea and vomiting. This may result in dehydration and in severe cases grayish-bluish skin. Transmission occurs primarily by drinking water or eating food that has been contaminated by the feces (waste product) of an infected person, including one with no apparent symptoms. 7. Ebola Another well-known killer is in the form of the Ebola virus, one of a dozen different types of hemorrhagic fevers, unpleasant diseases, accompanied by profuse bleeding. Ebola has become headline news in 1970, when the virus has spread in Zaire and Sudan, killing hundreds of people. In the following decades, the virus retained its deadly reputation, spreading lethal outbreaks across Africa. 8. Tuberculosis Tuberculosis in the past also called phthisis, phthisis pulmonalis, or consumption, is a common, and in many cases fatal, infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis. Tuberculosis typically attacks the lungs, but can also affect other parts of the body. 9. Smallpox The term "biological weapons" are usually creates mental images associated with sterile government labs, special uniforms and test tubes full of colorful liquids. Historically, however, the biological weapons takes a much more mundane forms: paper bags full of plague-infected fleas, or even an ordinary blanket, as it was during the war between France and India in 1763. 10. Anthrax The history of smallpox holds a unique place in medicine. One of the deadliest diseases known to humans, it is also the only human disease to have been eradicated by vaccination. Symptoms of a typical smallpox infection began with a fever and lethargy about two weeks after exposure to the Variola virus.
