The project was designed with the aim of countering that misconception that bacteria are always harmful to humans [20] and that humans are at war with bacteria. [21] In actuality, most strains of bacteria are harmless [13] if not beneficial for the human body. [22] Another of the project's goals is to foster public interest in microbiology. [17]

Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
Composition and distribution of gut microbiota in human body. In humans, the gut microbiota has the highest numbers and species of bacteria compared to other areas of the body. [9] The approximate number of bacteria composing the gut microbiota is about 10 13 –10 14 (10,000 to 100,000 billion). [10]
It is commonly found in the human microbiome and is associated with various infections. [8] Most of the species in this genus can be found among microbes of the skin, human vagina, nasal cavity, oral cavity and feces, often as a pathogen found in ovarian abscesses, chronic wounds and vaginal discharge.
