DRDO, JNU scientists develop more potent Anthrax vaccine

DRDO, JNU scientists develop more potent Anthrax vaccine

DRDO and JNU scientists have developed more potent Anthrax vaccine. They claim new vaccine is superior than existing ones as it can generate immune response to anthraxtoxin as well as spores.

Anthrax

Anthrax is a disease caused by Bacillus anthracis, a germ that lives in soil.

It affects animals such as cattle, sheep, and goats more often than people. People can get anthrax from contact with infected animals, wool, meat, or hides. It can cause three forms of disease in people.

How it is spread?

Anthrax does not spread directly from one infected animal or person to another; it is spread by spores. These spores can be transported by clothing or shoes.

Infection

  • In most cases, symptoms develop within seven days of exposure to the bacteria. The one exception is inhalation anthrax, which may take weeks after exposure before symptoms appear.
  • Respiratory infection in humans initially presents with cold or flu-like symptoms for several days, followed by pneumonia and severe (and often fatal) respiratory collapse.
  • Gastrointestinal (GI) infection in humans is most often caused by consuming anthrax-infected meat and is characterized by serious GI difficulty, vomiting of blood, severe diarrhea, acute inflammation of the intestinal tract, and loss of appetite.

Treatment:

  • The standard treatment for anthrax is a 60-day course of an antibiotic. Treatment is most effective when started as soon as possible.
  • Although some cases of anthrax respond to antibiotics, advanced inhalation anthrax may not. By the later stages of the disease, the bacteria have often produced more toxins than drugs can eliminate.
