Burkholderia pseudomallei Laboratory Exposure, Arizona, USA

Area of Science:

• Microbiology
• Infectious Diseases
• Public Health

Background:

• Melioidosis cases are increasing in the United States.
• Burkholderia pseudomallei (B. pseudomallei) reservoirs have been identified in the US Gulf Coast Region.
• B. pseudomallei poses a potential risk to laboratory personnel.

Purpose of the Study:

• To report an incidental B. pseudomallei laboratory exposure in Arizona.
• To highlight the potential occupational risk for US laboratory staff.
• To underscore the importance of B. pseudomallei awareness in laboratory settings.

Main Methods:

• Case description of an incidental laboratory exposure.
• Review of B. pseudomallei epidemiology in the US.
• Risk assessment for laboratory personnel.

Main Results:

• An incidental B. pseudomallei laboratory exposure was documented in Arizona.
• The presence of B. pseudomallei reservoirs in the US increases exposure risk.
• Laboratory staff are identified as a potentially at-risk population.

Conclusions:

• Accidental B. pseudomallei exposures can occur in US laboratories.
• Increased vigilance and safety protocols are necessary for laboratory staff.
• The geographic spread of B. pseudomallei necessitates ongoing risk assessment and mitigation efforts.
