Definition
Noun 1. A genus of bacteria: Heliobacter is a genus of bacteria characterized by a helical, curved, or straight rod shape with rounded ends. They are aerobic (requiring oxygen) and possess multiple flagella (whip-like structures for movement). These bacteria are specifically found living in the gastric mucosa (stomach lining) of primates, including humans.
Usage Notes
- The term is a scientific, taxonomic name for a genus. It is always capitalized.
- In medical and biological contexts, it is most famously associated with , a specific species within this genus that is a common cause of stomach ulcers and gastritis in humans.
- It is used as a countable noun when referring to the genus as a whole or to individual bacterial cells belonging to this genus.
Examples
- The discovery of Heliobacter revolutionized the understanding of stomach ulcers.
- Heliobacter species can survive in the highly acidic environment of the stomach.
- A biopsy confirmed the presence of Heliobacter in the patient's gastric tissue.
Advanced Usage
- The genus name is often used attributively (like an adjective) to describe related nouns (e.g., infection, research).
- In formal taxonomy, the name is italicized: .
Variants and Related Words
