However, while there are a plethora of different types of bacteria found in us, some of the most common types include Firmicutes, Bacteroidetes, Actinobacteria, Proteobacteria, and Fusobacteria, with each of these groups having their own distinct cell structure and metabolic functions, while each also play their own unique role in our overall health.
