Definition

Noun: 1. A family of filamentous anaerobic bacteria: Actinomycetaceae is the scientific name for a taxonomic family of bacteria. These bacteria are characterized by their filamentous, branching growth form (similar to fungi) and their anaerobic nature, meaning they thrive in environments without oxygen.

Usage Notes

• This is a highly specialized, scientific term used primarily in microbiology, medicine (particularly in infectious disease and dentistry), and taxonomy.
• It is a proper noun and is always capitalized: .
• In everyday language, one would typically refer to the diseases they cause (e.g., actinomycosis) or describe them as "actinomycete bacteria" rather than use the full family name.

Examples of Usage

• Scientific Context:
  • The laboratory report identified the pathogen as a member of the family Actinomycetaceae.
  • Microbial analysis of the soil sample revealed a high prevalence of Actinomycetaceae.
  • Antibiotics effective against Actinomycetaceae were prescribed for the jaw infection.

Advanced Usage

• Taxonomic Hierarchy: In scientific classification, is a family within the order . Key genera within this family include and , which contain species pathogenic to humans.
