Bacillus anthracis strain Shikan-NIID

Bacillus anthracis strain Shikan-NIID is a Gram-positive, rod-shaped bacterium that serves as the causative agent of anthrax. It is a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen, and is classified as a chemoheterotroph, relying on organic compounds for energy. This strain is mesophilic, with an optimal growth temperature of 37°C, and is capable of sporulation, allowing it to form resilient spores for survival in adverse conditions. The habitat of B. anthracis strain Shikan-NIID is primarily soil, where it exists as a free-living organism. It does not exhibit mobility, despite having flagella. The bacterium has two replicons and a single membrane structure, which is typical for its genus. B. anthracis has a significant pathogenicity profile, primarily affecting various hosts, including Homo sapiens, Bos (cattle), Ovis aries (sheep), and other mammals such as Equus caballus (horses) and Capra hircus (goats). The bacterium is known to cause anthrax and anthrax-like diseases, including inhalation anthrax, which poses serious health risks to both livestock and humans. Understanding the ecological role of Bacillus anthracis strain Shikan-NIID in soil environments is crucial, as it highlights the bacterium's potential for transmission between wildlife, livestock, and humans, emphasizing the importance of monitoring soil health and animal populations in preventing outbreaks of anthrax.
