Memory Aids
Mnemonic
Think of a 'fuse' (long and thin) and 'bacteria' – these are long, thin, spindle-shaped bacteria.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- The word is a direct Latin borrowing. It should be transliterated as 'фузобактерии'. Avoid confusing it with more common bacterial names like 'бациллы' or 'палочки' without the specific 'fusiform' nuance.
Common Mistakes
- Treating it as singular ('a fusobacteria' – incorrect; correct: 'a fusobacterium' or 'fusobacteria').
- Confusing spelling: 'fusobakteria' or 'fuzobacteria'.
- Using it in a non-scientific context where it would not be understood.

FAQ
Frequently Asked Questions
It is a plural noun. The singular form is 'fusobacterium'.
As a technical term, most people would only encounter it in a medical or dental context, for instance, in a lab report concerning an infection.
Not always. While some species are pathogenic and linked to diseases, others are part of the normal human microbiota in areas like the mouth and colon.
They are typically spindle-shaped or fusiform, which is the origin of their name ('fuso-' meaning spindle).
