vancomycin
C2Highly technical; primarily medical and pharmaceutical.
Definition
Meaning
A potent glycopeptide antibiotic used to treat serious bacterial infections, particularly those resistant to other antibiotics.
A complex glycopeptide compound produced by the bacterium Amycolatopsis orientalis, historically crucial in treating infections caused by Gram-positive bacteria like Staphylococcus aureus, especially methicillin-resistant strains (MRSA). Its use is generally reserved for severe cases due to potential side effects and the need to prevent the development of further resistance.
Linguistics
Semantic Notes
The term functions almost exclusively as a mass noun (e.g., 'administer vancomycin'). It belongs to a class of drugs named with the '-mycin' suffix, indicating an origin from actinobacteria (though not all are still produced this way).

Connotations
Identical in both varieties: connotes a powerful, last-resort treatment.
Frequency
Equally low-frequency in general English but standard within medical contexts in both the UK and US.

Examples
By Part of Speech
adjective
British English
- The vancomycin-resistant enterococci outbreak was contained.

Examples
By CEFR Level
- The doctor prescribed a strong antibiotic called vancomycin for the infection.
- Due to the MRSA diagnosis, the medical team initiated intravenous vancomycin therapy and closely monitored the patient's renal function.
- The emergence of vancomycin-resistant strains poses a significant challenge to modern healthcare systems.
Learning
Memory Aids
Mnemonic
Think: 'VANquish CO-MY infection' – vancomycin vanquishes complex bacterial infections.
Conceptual Metaphor
A LAST-LINE DEFENDER or a SILVER BULLET (used sparingly for the toughest foes).

Common Pitfalls
Translation Traps (for Russian speakers)
- The direct Russian translation is 'ванкомицин' (vankomitsin), a clear cognate. No significant trap, but ensure correct transliteration in technical writing.
Common Mistakes
- Misspelling as 'vancomyocin' or 'vankomycin'.
- Using it as a countable noun (e.g., 'a vancomycin').
- Mispronouncing the first syllable as 'van-' like the vehicle, instead of 'vank-'.
- Confusing it with other '-mycin' antibiotics like erythromycin.

FAQ
Frequently Asked Questions
No, vancomycin is a glycopeptide antibiotic, which is chemically distinct from penicillins (which are beta-lactams). It is often used when patients are allergic to penicillin or when bacteria are resistant to it.
Vancomycin is poorly absorbed from the gastrointestinal tract. Intravenous administration ensures the drug reaches effective concentrations in the bloodstream to fight systemic infections. An oral form exists but is only used for specific gut infections.
It is a common, non-allergic reaction (characterized by flushing, itching, and rash on the face, neck, and upper body) that can occur if vancomycin is infused too quickly. Slowing the infusion rate usually prevents it.
VRE stands for Vancomycin-Resistant Enterococci. It refers to strains of Enterococcus bacteria that are not killed by vancomycin, representing a serious type of antibiotic resistance.
