[Melioidosis: an emerging tropical disease]

Area of Science:

• Microbiology
• Infectious Diseases
• One Health

Context:

• Melioidosis is a significant zoonotic disease caused by Burkholderia pseudomallei, a Gram-negative bacterium found in soil.
• It is endemic in tropical regions of Southeast Asia and Northern Australia, with sporadic cases globally.
• The infection presents with diverse clinical manifestations, from acute septicemia to chronic conditions.

Purpose:

• To provide a comprehensive overview of melioidosis, its causative agent, and its impact on human and animal health.
• To highlight the challenges in diagnosis and treatment due to antibiotic resistance and lack of a vaccine.
• To underscore the public health significance and potential bioterrorism concerns associated with Burkholderia pseudomallei.

Summary:

• Burkholderia pseudomallei causes melioidosis, a variable infection affecting humans and animals.
• Treatment is challenging due to widespread antibiotic resistance and the absence of a vaccine, leading to common relapses.
• The bacterium's high virulence and resistance profile classify it as a biological risk agent.

Impact:

• Increased awareness of melioidosis as a critical infectious disease in endemic and non-endemic areas.
• Highlights the urgent need for novel therapeutic strategies and vaccine development against Burkholderia pseudomallei.
• Emphasizes the importance of One Health approaches for managing zoonotic diseases with bioterrorism potential.
