Bacilli are a type of rod-shaped bacteria that can be found in various environments including soil, water, and the human body. They are commonly classified into two groups based on their ability to form spores: spore-forming bacilli and non-spore-forming bacilli. Some species of Bacillus, a genus of spore-forming bacilli, are known for their ability to produce antibiotics, while others can cause food spoilage and disease. Other bacterias such as Lactobacillus and Escherichia coli are non-spore-forming bacilli that play important roles in human health as probiotics and in digesting food. Overall, bacilli are an important and diverse type of bacteria that can have both positive and negative effects on the environment and human health.
