Abstract:
Actinomyces is a rare aetiology of infections affecting the perianal region and natal cleft. Recognition of this microorganism is essential to deliver targeted antimicrobial therapy following surgical intervention. We present a series of 15 pilonidal and perianal infections associated with this microorganism. Actinomyces turicensis was the only strain of Actinomyces isolated. A total of 14 out of 15 cases had concomitant microorganisms isolated from microbiology specimens. Mixed anaerobes (n = 14) were the most common concomitant pathogens followed by Streptococcus milleri (n = 3), Staphylococcus aureus (n = 1), Citrobacter (n = 1) and Coliform bacteria (n = 1). All patients, except one who was pregnant at time of diagnosis, underwent surgical drainage with or without further oral antibiotic therapy. Coloproctologists need to consider Actinomyces as a clinically significant pathogen in the context of perianal and pilonidal infections.
Insights
Actinomyces, a rare cause of perianal and pilonidal infections, requires recognition for effective treatment. This study identified Actinomyces turicensis in 15 cases, often with mixed bacterial infections, highlighting its clinical significance.
Area of Science:
- Microbiology
- Infectious Diseases
- Colorectal Surgery
Background:
- Actinomyces species are uncommon causes of infections in the perianal and natal cleft regions.
- Prompt identification of Actinomyces is crucial for guiding appropriate antimicrobial therapy post-surgery.
