Học thuậtThân thiện
Definition
- Adjective:
- Of or pertaining to or resembling a coccus: Relating to, connected with, or having the shape of a coccus (a spherical or roughly spherical bacterium).
Usage
- The word "coccal" is a specialized adjective used primarily in microbiology and medical contexts to describe bacteria, infections, or structures that are spherical in shape or related to cocci.
- It is typically used attributively (before a noun) to modify terms like "infection," "morphology," or "bacteria."
Examples
- The laboratory report identified a coccal infection in the sample.
- Under the microscope, the bacteria exhibited a distinct coccal morphology.
- Coccal forms are often found in clusters or chains, such as staphylococci or streptococci.
Advanced Usage
- "Coccal arrangement": Refers to the specific pattern in which spherical bacteria group together (e.g., in pairs, chains, or clusters).
- The coccal arrangement of the bacteria suggested it was a Streptococcus species.
- Used in compound scientific terms where "coccal" specifies the bacterial shape, even if the full term is a compound noun (e.g., "coccal bacterium"). The core adjective "coccal" still means "of or like a coccus."
