Final answer:
Bacillus anthracis is a common rod-shaped bacterium known for producing endospores and causing anthrax. It is an aerobe or facultative anaerobe part of the Bacillus genus. This distinguishes it from other non-endospore-forming bacteria such as Escherichia coli and Pseudomonas aeruginosa.
Step-by-step explanation:
Bacillus anthracis is one of the most common rod-shaped bacteria that produce endospores. This organism is part of the genus Bacillus, which includes aerobes or facultative anaerobes. Bacillus anthracis is known for causing anthrax in cattle and humans. These bacteria are bacillus in shape and can produce endospores, which are dormant forms of bacteria that allow them to survive in extreme conditions. Unlike B. anthracis, Escherichia coli does not form endospores, and Pseudomonas aeruginosa, although rod-shaped, is not an endospore-forming bacterium. Clostridium tetani, on the other hand, is also an endospore-forming rod-shaped bacteria but is obligate anaerobe and is best known for causing tetanus.
