Abstract:
Actinomyces species are part of the commensal flora of the mucous membranes of the oropharynx, gastrointestinal tract and female genital tract. Actinomyces europaeus is a short, nonmotile, facultative anaerobic rod first described in 1997, susceptible in vitro to a wide range of b-lactam antibiotics which are regarded as first choice. In this report we described the case of A. europaeus infection in a young female patient admitted to Intensive Care Unit and the possible damage of vascular endothelium due to a chronic progressive actinomycosis that at first involved neck soft tissue, then cervical lymphnodes, and finally extended to the vascular structure.
Insights
Actinomyces europaeus, a rare bacterium, can cause severe chronic infections. This case highlights its potential to damage vascular endothelium, extending from soft tissue to blood vessels.
Area of Science:
- Microbiology
- Infectious Diseases
- Vascular Biology
Background:
- Actinomyces species are commensal flora of human mucous membranes.
- Actinomyces europaeus, identified in 1997, is susceptible to beta-lactam antibiotics.
- Chronic actinomycosis can lead to significant tissue damage.
Observation:
- A young female patient in the ICU presented with a chronic progressive Actinomyces europaeus infection.
- The infection initially affected neck soft tissue and cervical lymph nodes.
- The infection extended to involve the vascular structure.
Findings:
- Actinomyces europaeus caused a progressive infection with vascular endothelium damage.
- The case demonstrates a rare but severe manifestation of actinomycosis.
- Beta-lactam antibiotics are considered first-choice treatment for Actinomyces europaeus.
Implications:
- This case underscores the importance of recognizing and treating Actinomyces europaeus infections promptly.
- Understanding the pathogenesis of A. europaeus is crucial for managing severe cases.
- Further research into the vascular complications of actinomycosis is warranted.

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
