actinomycosis
C2Technical / Medical
Definition
Meaning
A chronic bacterial infection caused by Actinomyces species, typically affecting the face, neck, or lungs.
A rare, slowly progressive granulomatous infectious disease, often characterized by abscess formation, tissue fibrosis, and draining sinuses, primarily caused by Actinomyces israelii and other filamentous bacteria. It is not typically contagious.
Linguistics
Semantic Notes
The term is highly specific to medicine and microbiology. It denotes a specific pathological condition and is not used metaphorically.

Examples
By CEFR Level
- The vet said the cow had a disease called actinomycosis.
- Actinomycosis is a rare infection that can affect both humans and animals.
- The patient's cervicofacial actinomycosis presented as a hard, painless swelling with draining sinuses.
- Empirical antibiotic therapy for suspected pulmonary actinomycosis typically involves high-dose penicillin or amoxicillin for an extended period, often six to twelve months, to penetrate the fibrotic tissue and sulfur granules characteristic of the disease.
Learning
Memory Aids
Mnemonic
Think 'action' + 'mycosis' (fungal disease). It's an infection caused by bacteria that look and behave somewhat like fungi.

FAQ
Frequently Asked Questions
No, actinomycosis is generally not contagious. It is caused by bacteria that are normal inhabitants of the mouth and gastrointestinal tract and only cause disease when they breach mucosal barriers.
It comes from Greek: 'aktis' (ray) + 'mykes' (fungus) + '-osis' (condition), referring to the ray-like appearance of the bacterial filaments under the microscope, originally mistaken for fungi.
Cervicofacial actinomycosis, often called 'lumpy jaw,' is the most common presentation, typically following dental surgery or trauma to the mouth.
Treatment involves prolonged antibiotic therapy (often penicillin-based for several months) and may require surgical drainage of abscesses.
