Abstract:
Paratuberculosis is a chronic intestinal disease of animals caused by Mycobacterium avium subsp. paratuberculosis (MAP), which has some pathological features similar to Crohn's disease (CD) in humans. The presence of MAP in food for human consumption and in affected tissues of patients with CD has been detected. Therefore, a causal association between this microorganism and the disease in humans, has been postulated. However, several related studies have failed to confirm this hypothesis and the scientific acceptance of MAP as a zoonotic agent remains controversial. This review presents the main findings related to this issue, contrasting evidences for and against an association between MAP and CD. The need to promote national studies focusing on this area is suggested.
Insights
Mycobacterium avium subsp. paratuberculosis (MAP) may cause Crohn's disease (CD) in humans, but evidence remains controversial. Further research is needed to confirm if MAP is a zoonotic agent linked to CD.
Area of Science:
- Veterinary Medicine
- Human Gastroenterology
- Microbiology
Context:
- Paratuberculosis, a chronic intestinal disease in animals, shares pathological similarities with human Crohn's disease.
- Mycobacterium avium subsp. paratuberculosis (MAP) has been detected in food products and tissues of Crohn's disease patients, suggesting a potential link.
- The hypothesis of MAP as a zoonotic agent causing Crohn's disease is debated within the scientific community.
Purpose:
- To review and contrast the evidence supporting and refuting an association between MAP and Crohn's disease.
- To critically evaluate the current scientific understanding of MAP's role in human health.
- To highlight the need for further investigation into the potential zoonotic nature of MAP.
Summary:
- This review examines the controversial link between Mycobacterium avium subsp. paratuberculosis (MAP) and Crohn's disease (CD).
- Evidence for and against MAP as a causative agent in CD is presented and contrasted.
- The review underscores the ongoing scientific debate regarding MAP's zoonotic potential.
Impact:
- Provides a comprehensive overview of the current state of research on MAP and CD.
- Identifies gaps in knowledge and areas requiring further investigation.
- Emphasizes the importance of targeted national studies to resolve the controversy surrounding MAP's role in human disease.

Inflammatory Bowel Disease III: Crohn's Disease
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 transmural...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
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...
