Summary
This study successfully induced acute appendicitis in rabbits using both mechanical obstruction and ischemic models. Escherichia coli was identified as the primary bacterium in appendicitis-affected appendices and peritonitis exudates.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Microbiology
Context:
- Acute appendicitis is a common surgical emergency.
- Understanding its pathogenesis is crucial for effective treatment.
- Animal models are vital for studying complex diseases like appendicitis.
Purpose:
- To create an animal model of acute appendicitis in rabbits.
- To investigate the histological changes in the appendix during appendicitis.
- To identify the bacterial flora associated with appendicitis and peritonitis.
Summary:
- This study utilized mechanical obstruction and ischemic ligation of the vermiform appendix in rabbits to induce acute appendicitis.
- Histological examination revealed distinct anatomopathological alterations consistent with appendicitis.
- Escherichia coli was identified as the predominant bacterium in both the normal appendix flora and peritonitis exudates.
Impact:
- Establishes a reliable rabbit model for acute appendicitis research.
- Provides insights into the histopathological progression of appendicitis.
- Identifies key bacterial species involved in appendicitis pathogenesis and associated peritonitis.
