acinetobacter
Very LowTechnical/Scientific
Definition
Meaning
A genus of Gram-negative bacteria commonly found in soil, water, and hospital environments, known for causing opportunistic infections.
In medical contexts, refers specifically to pathogenic species within this genus, particularly Acinetobacter baumannii, which is associated with hospital-acquired infections like pneumonia, bloodstream infections, and wound infections, often showing antibiotic resistance.
Linguistics
Semantic Notes
The term is almost exclusively used in medical, microbiological, and public health contexts. It functions primarily as a taxonomic name but is often used metonymically to refer to infections caused by these bacteria.

Examples
By Part of Speech
adjective
British English
- The Acinetobacter infection required isolation.
- Acinetobacter colonization is a risk factor.
American English
- The Acinetobacter outbreak was contained.
- Acinetobacter resistance patterns were analyzed.
Examples
By CEFR Level
- The doctor said the infection was caused by a bacteria called Acinetobacter.
- Acinetobacter infections are difficult to treat because the bacteria are often resistant to multiple antibiotics.
- The study focused on the genomic epidemiology of carbapenem-resistant Acinetobacter baumannii isolates from intensive care units across several hospitals.

Memory Aids
Mnemonic
Think: 'A city (aci) net (net) catches bacteria (bacter).' Imagine a net over a city hospital catching these specific bacteria.
Conceptual Metaphor
Often conceptualized as a 'SUPERBUG' or 'HOSPITAL SCAVENGER' due to its association with healthcare settings and antibiotic resistance.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally. The established Russian term is 'ацинетобактер'.
- Avoid confusing it with more general terms like 'бактерия' (bacteria).
Common Mistakes
- Misspelling as 'acinitobacter' or 'acenitobacter'.
- Using it as a countable noun in plural without context (e.g., 'three acinetobacters' is non-standard; prefer 'three Acinetobacter isolates' or 'strains').

Frequently Asked Questions
It can be, particularly for immunocompromised patients in healthcare settings, as some strains are resistant to many antibiotics.
Yes, it can be found in soil and water, but serious infections are predominantly associated with healthcare environments.
It means that strains of the bacteria do not respond to treatment with multiple classes of antibiotics, making infections very hard to cure.
No, it is a genus of bacteria, not a virus.
