Definition

Noun: A taxonomic category (genus) of Gram-positive, spherical bacteria (cocci) that typically occur in irregular, grape-like clusters. This genus includes many species that are pathogenic to humans and animals, often causing skin infections, food poisoning, and more serious conditions.

Usage

• The word "genus Staphylococcus" is used in formal, scientific contexts such as microbiology, medicine, and taxonomy. It refers to the entire group or category of bacteria sharing these characteristics.
• It is typically used as a singular noun when referring to the taxonomic group itself.
