Mesenteric lymphadenitis caused by Yersinia enterocolitica

Area of Science:

• Microbiology
• Infectious Diseases
• Gastroenterology

Background:

• Yersiniosis is a zoonotic infection caused by Yersinia enterocolitica, a Gram-negative bacterium.
• Transmission occurs through contaminated food (pork, unpasteurized milk) or secondary contamination.
• Clinical manifestations vary based on patient factors and bacterial virulence.

Observation:

• Yersinia enterocolitica can manifest in diverse clinical forms, including food poisoning, colitis, and mesenteric lymphadenitis.
• The study presents a rare case involving concurrent appendicitis and Yersinia enterocolitica infection of the mesenteric lymph nodes.

Findings:

• The coexistence of appendicitis and Yersinia enterocolitica in mesenteric lymph nodes represents an uncommon clinical presentation.
• This case underscores the broad spectrum of Yersiniosis presentations.

Implications:

• Accurate diagnosis of Yersiniosis requires consideration of its varied clinical presentations, including rare co-occurrences.
• Understanding these presentations is crucial for effective patient management and treatment strategies.
