Large intestinal diverticulitis, an inflammation of pouches in the gut, was observed in endangered leatherback sea turtles. This condition, characterized by bacterial infection and inflammation, appears unrelated to mortality but poses potential complications.
Area of Science:
- Veterinary Medicine
- Marine Biology
- Wildlife Health
Background:
- Leatherback sea turtles (Dermochelys coriacea) are globally distributed and endangered.
- Limited data exists on diseases affecting this species.
- Initial observations noted solitary large intestinal diverticulitis in multiple leatherbacks.
Purpose of the Study:
- To investigate the prevalence and characteristics of large intestinal diverticulitis in leatherback sea turtles.
- To analyze pathological findings associated with this condition.
Main Methods:
- A multi-institutional review of cases involving leatherback sea turtles with large intestinal diverticulitis.
- Analysis of complete medical records for 31 subadult and adult turtles.
- Histopathological examination of lesions and bacterial isolation.
Main Results:
- All 31 turtles presented with a single, large (up to 9.0 cm diameter), exudate-filled diverticulum in the large intestine.
- Lesions were chronic, showing inflammation, bacterial presence, muscularis attenuation, and ulceration.
- Morganella morganii was isolated in three cases.
- Diverticulitis was not the cause of death in any reviewed case.
Conclusions:
- Large intestinal diverticulitis is a distinct pathological finding in leatherback sea turtles.
- While not directly causing death, the condition carries risks of perforation and other complications.
- Further research is needed to understand the etiology and long-term impact of diverticulitis in this endangered species.

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...

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
