Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. ...

Orders Flavobacteriales The class Flavobacteria is composed of a single order of environmental bacteria[1]. ^ Bergeys Manual of Systematic Bacteriology, 2nd ed. ...
| The phylum Bacteroidetes is composed of three large classes of bacteria that are widely distributed in the environment, including in soil, in sediments, sea water and in the guts of animals. Phylum (plural: phyla) is a taxon used in the classification of animals, adopted from the Greek phylai the clan-based voting groups in Greek city-states. ...

By far, the Bacteroidales class are the most well-studied, including the genus Bacteroides (an abundant organism in the feces of warm-blooded animals including humans), and Porphyromonas, a group of organisms inhabiting the human oral cavity. Scientific classification or biological classification refers to how biologists group and categorize extinct and living species of organisms. ...
Species etc. ...
Feces, faeces, or fæces (see spelling differences) In humans, defecation may occur (depending on the individual and the circumstances) from once every two or three days to several times a day. ...
The mouth, also known as the buccal cavity or the oral cavity, is the opening through which an animal or human takes in food. ...
Members of the genus Bacteroides are opportunistic pathogens. Rarely are members of the other two classes pathogenic to humans. Opportunistic infections are infections caused by organisms and usually do not cause disease in a person with a healthy immune system, but can affect people with a poorly functioning or suppressed immune system. ...
A pathogen or infectious agent is a biological agent that causes disease or illness to its host. ...
Researcher Jeffrey Gordon and his colleagues found that obese humans and mice had intestinal flora with a lower percentage of a family of bacteria called Bacteroidetes and more Firmicutes. However, they are unsure if Bacteroidetes prevent obesity or if these intestinal flora are merely preferentially selected by intestinal conditions in those who are not obese.[1][2][3] Obesity is an excess storage of fat and can affect any mammal, such as the mouse on the left. ...
Classes Bacilli Clostridia Mollicutes The Firmicutes are a division of bacteria, most of which have Gram-positive cell wall structure. ...
