Paratuberculosis in captive and free-ranging wildlife

Area of Science:

• Veterinary Medicine
• Infectious Diseases
• Wildlife Health

Background:

• Mycobacterium avium subsp. paratuberculosis (MAP) causes Johne’s disease, a fatal infection affecting all ruminant species, including exotic and domestic animals.
• Young ruminants are particularly susceptible to MAP infection via the fecal-oral route, posing a significant risk in zoological collections.
• MAP infection is a critical concern for wildlife conservation programs aiming to protect rare animal genetics.

Purpose of the Study:

• To highlight the susceptibility of all ruminant species to Mycobacterium avium subsp. paratuberculosis (MAP).
• To emphasize the diagnostic challenges and recommended methods for MAP detection in non-domestic species.
• To address the implications of MAP infection for zoological hoofstock collections and rare animal conservation.

Main Methods:

• Review of existing literature on MAP infection in ruminants.
• Discussion of diagnostic techniques, including Polymerase Chain Reaction (PCR) and culture.
• Analysis of the epidemiological role of nonruminant wildlife reservoirs.

Main Results:

• All ruminant species, regardless of origin or habitat, are susceptible to MAP infection.
• Young ruminants are most vulnerable to infection through fecal-oral transmission.
• Nonruminant wildlife are rarely true reservoirs for sustaining MAP infection independently.

Conclusions:

• MAP infection presents a substantial risk to zoological collections and the conservation of rare ruminant genetics.
• Accurate diagnosis in non-domestic species is crucial for disease management and prevention.
• Effective control strategies are necessary to mitigate the impact of MAP on vulnerable animal populations.
