What type of bacteria is anthrax known to be?

1. A resistant and stable bacteria

2. A highly contagious virus

3. A non-pathogenic fungus

4. A rapidly mutating organism

The correct answer is: A resistant and stable bacteria

Anthrax is caused by the bacterium Bacillus anthracis, which is known for its resilience and stability in the environment. This bacterium forms spores that can survive in harsh conditions for long periods, making it particularly resistant to environmental stressors such as heat and desiccation. This characteristic allows anthrax spores to persist in soil and animal products, leading to potential infections in livestock and humans. The correct choice emphasizes the stable and resistant nature of this bacterium, which is crucial for understanding how anthrax can spread and persist in both natural and agricultural settings. Recognizing these features is vital for individuals working in emergency care and public health, as it underscores the importance of preventive measures, especially in areas at risk for outbreaks or bioterrorism events.
