Mucosal invasion in campylobacter enteritis
Abstract:
Campylobacter fetus subspecies jejuni has recently been recognized as a significant cause of enteritis in humans. The organism has been previously postulated to cause illness by direct invasion of the mucosa of the gastrointestinal tract, but this has not been documented. Reported is a case of Campylobacter enteritis in which mucosal ulceration and crypt sbscesses were seen on rectal biopsy, suggesting that the pathogenesis of Campylobacter fetus enteritis involves direct mucosal invasion.
Insights
Campylobacter fetus subspecies jejuni causes human enteritis. This case shows direct mucosal invasion, evidenced by rectal biopsy findings of ulceration and abscesses, confirming a key pathogenic mechanism.
Area of Science:
- Microbiology
- Gastroenterology
- Pathogenesis
Background:
- Campylobacter fetus subspecies jejuni is an emerging cause of human enteritis.
- The pathogenic mechanism, specifically direct mucosal invasion, has been previously unconfirmed.
Observation:
- A patient presented with symptoms of Campylobacter enteritis.
- Rectal biopsy was performed for diagnostic evaluation.
Findings:
- The rectal biopsy revealed significant mucosal ulceration.
- Evidence of crypt abscesses was also observed in the biopsy.
Implications:
- These findings provide direct evidence for Campylobacter fetus subspecies jejuni invading the gastrointestinal mucosa.
- This supports direct mucosal invasion as a primary mechanism in Campylobacter enteritis pathogenesis.
