myxobacteria
Very LowTechnical/Scientific
Definition
Meaning
A group of gram-negative, rod-shaped bacteria known for their unique social behavior of forming fruiting bodies when nutrients are scarce.
Also known as myxobacteria or slime bacteria; a fascinating order of bacteria studied for their complex life cycle, which includes gliding motility, cooperative feeding, and multicellular development into spore-filled structures. They are a rich source of novel bioactive compounds.
Linguistics
Semantic Notes
Used almost exclusively in microbiology, biochemistry, and evolutionary biology. The singular form 'myxobacterium' is rarely used; the term is typically used in its plural form to refer to the group as a whole.
Dialectal Variation
British vs American Usage
Differences
No significant lexical or spelling differences. Pronunciation differs (see IPA). The term is equally technical in both varieties.
Connotations
Purely scientific, with no cultural connotations.
Frequency
Identically low frequency in both varieties, confined to specialist literature.

Examples
By Part of Speech
verb
British English
- The cells will myxobacteriate under starvation conditions. (Note: This is a hypothetical/rare derivation)
American English
- The culture failed to myxobacteriate. (Note: This is a hypothetical/rare derivation)
adjective
British English
- The myxobacterial lifecycle is fascinating.
- They observed myxobacterial swarming.
American English
- They isolated a myxobacterial compound.
- The myxobacterial genome was sequenced.
Examples
By CEFR Level
- Myxobacteria are interesting because they behave like a team.
- Scientists study myxobacteria to understand how life became complex.
- Under nutrient deprivation, myxobacteria aggregate to form multicellular fruiting bodies.
- The predatory behaviour of myxobacteria involves the collective secretion of lytic enzymes.
Learning
Memory Aids
Mnemonic
Think: 'MIX-o-bacteria'. They MIX together socially to form complex fruiting bodies.
Conceptual Metaphor
THE BACTERIA ARE A COOPERATIVE SOCIETY (e.g., 'myxobacteria hunt in packs', 'they build fruiting structures').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calques like 'слизневые бактерии' in formal scientific English; 'myxobacteria' or 'slime bacteria' is standard.
- Do not confuse with 'миксомицеты' (myxomycetes), which are slime molds, a completely different type of organism.
Common Mistakes
- Incorrect singular: 'a myxobacteria' (correct: 'a myxobacterium' or 'a myxobacterial cell').
- Misspelling: 'mixobacteria'.
- Mispronunciation: putting primary stress on the first syllable.

FAQ
Frequently Asked Questions
No, myxobacteria are generally not human pathogens. They are primarily soil bacteria studied for their interesting biology and production of useful enzymes and antibiotics.
The singular is 'myxobacterium', but in practice, scientists often refer to 'a myxobacterial cell' or use the plural form generally for the group.
They are important model organisms for studying multicellularity, social evolution, and cell signalling. They are also prolific producers of novel secondary metabolites with potential pharmaceutical applications.
In British English: /ˌmɪksəʊbækˈtɪərɪə/. In American English: /ˌmɪksoʊbækˈtɪriə/. The stress is on the 'teer'/'tir' syllable.
