Evaluation of culture- and PCR-based methods for detecting Burkholderia pseudomallei in soil samples in Thailand

This study demonstrates the importance of using effective methods for detection of B. pseudomallei in environmental samples. For culture-based approaches, enrichment in ACER broth followed by subculture on Ashdown agar demonstrated enhanced bacterial recovery compared to direct culture on Ashdown agar alone. There was limited detection of B. pseudomallei in soil by real-time PCR, and lack of an association between environmental detection methods and human seroprevalence. These findings highlight the need for integrated, multi-dimensional surveillance approaches.
