Bacilli are a type of bacteria that are short and rod-shaped in appearance. They are responsible for causing diseases such as tetanus and anthrax. Cocci are spherical-shaped bacteria, and therefore, do not fit the description of being rod-shaped. They are responsible for causing diseases such as strep throat and pneumonia. Spirilla are spiral-shaped bacteria, and while they can cause diseases such as syphilis and Lyme disease, they do not fit the description of being rod-shaped. Vibrios are curved rod-shaped bacteria, but they typically cause gastrointestinal illnesses, such as cholera, rather than tetanus. Therefore, they do not fit the description of being responsible for diseases such as tetanus.
