Anthrax is a disease caused by bacteria that may remain in the soil for how many years or longer?

1. 10

2. 20

3. 30

4. 40

The correct answer is: 40

Anthrax is caused by the bacterium Bacillus anthracis, which is notable for its ability to form spores that can survive for extended periods in the environment. These spores can remain viable in soil for decades, which is a key reason why anthrax outbreaks often occur in regions where the disease has previously been reported. The spores can withstand extreme conditions, allowing them to persist for many years. The correct answer indicates that anthrax spores can remain in the soil for 40 years or longer. This long viability plays a significant role in the epidemiology of the disease, as grazing animals can become infected by coming into contact with these spores, and there is a risk of transmission to humans as well. The longevity of the spores in the soil highlights the importance of proper management and monitoring in agricultural practices to prevent outbreaks.
