Desulfovibrio orale is a pathogenic species of sulfate-reducing bacteria that is associated with periodontal disease, which affects the gums.

Desulfovibrio orale

Sulfate-reducing bacteria (SRBs) are a group of gram-negative bacteria, primarily within the class Deltaproteobacteria, that utilize sulfate as the terminal electron acceptor in their electron transport chain.

Deltaproteobacteria is a small class of gram-negative bacteria that includes species capable of reducing sulfate or elemental sulfur. Some members of this class act as scavengers and can form myxospores with multicellular fruiting bodies.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

Sulfate-Reducing Bacteria

Bdellovibrio is a genus of Deltaproteobacteria that are parasites of other gram-negative bacteria, invading their host's periplasm to feed on host proteins and polysaccharides, ultimately killing the host.

Bdellovibrio

Myxobacteria are soil-dwelling, motile, and highly social Deltaproteobacteria that scavenge inorganic compounds, interact with other bacteria, and can form multicellular, macroscopic fruiting bodies as well as metabolically inactive myxospores.
