Whether it's a deadly cobra, spider or scorpion, antivenoms [1] offer us one final lifeline against otherwise fatal stings and bites.
At current estimates, snake [2] bites alone are responsible for up to 100,000 deaths every year, so the production and development of antivenom is vitally [3] important.
The process was devised in 1894 by French bacteriologist Albert Calmette, a student of Louis Pasteur.

The poisonous animal is 'milked' for venom by gently [4] pressing on the venom glands to test on horses, goats, etc.
The chosen animal is injected with a minute amount of the venom (so little they suffer no ill effects) and its [5] body responds by creating antibodies.
These antibodies are then collected via a small blood sample taken from the animal and cooled at two to eight degrees Celsius.
A centrifuge (inset above) is then [6] used to separate the plasma in the blood before enzymes are introduced to break down the antibody to get antivenom.
Types of venom [7] vary considerably between species so this process must be repeated for a wide range of animals.
