Definition
Noun: * Family Micrococcaceae: A taxonomic family of bacteria. These are typically spherical or elliptical, usually aerobic, eubacteria. A distinguishing characteristic is their production of yellow, orange, or red pigments. The family includes some toxin-producing forms, as well as harmless commensals (organisms living in/on another without harming it) and saprophytes (organisms living on decaying organic matter).
Usage Notes
- This is a highly specialized, scientific term used in microbiology and taxonomy.
- It is always treated as a singular noun when referring to the taxonomic group itself (e.g., "The family Micrococcaceae is...").
- In formal scientific writing, the name is often italicized: .
Examples
- Scientific Context:
- Staphylococcus and Micrococcus are two well-known genera within the family Micrococcaceae.
- The study focused on the pigment production capabilities of various members of the family Micrococcaceae.
- According to the latest phylogenetic analysis, this bacterium belongs to the family Micrococcaceae.
Advanced Usage
- Taxonomic Hierarchy: The term is used within the standard biological classification system (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species). For example: Order → Family → Genus .
- Clinical Context: In medical microbiology, identifying an organism as part of the family Micrococcaceae can be an initial step in diagnosing an infection, as it includes both pathogenic and non-pathogenic species.
Variants and Related Words
- Micrococcaceae: The core family name, often used interchangeably with "the family Micrococcaceae."
- Micrococcal (adj): Of or relating to the Micrococcaceae. (e.g., micrococcal nuclease).
- Genus Micrococcus: The type genus of this family.
- Genus Staphylococcus: A medically significant genus within this family.
Synonyms
- Taxonomic Synonyms: There are no true common-language synonyms. In outdated taxonomic schemes, the classification may have differed, but in current standard taxonomy, "family Micrococcaceae" is the accepted term.
Related Phrases / Terms
- Gram-positive cocci: A descriptive term based on staining and shape that includes many members of the family Micrococcaceae.
- Coagulase-positive/negative: A key test used to differentiate pathogenic (a member of this family) from other, less harmful staphylococci and micrococci.
- Commensal flora: Refers to the harmless or beneficial bacteria, including some from the family Micrococcaceae, that normally live on the skin or mucous membranes.
