Case in brief
A 69-year-old man of Thai descent presented in Sydney, Australia, with a diagnosis of melioidosis. The identification of Burkholderia pseudomallei was complicated by a misreporting as B. thailandensis due to inadequate MALDI-TOF-MS database software. The diagnosis was ultimately confirmed through clinical suspicion and understanding of the misclassification, leading to appropriate management.
What made this case unusual
The case underscores the technical challenges in identifying Burkholderia pseudomallei in a non-endemic area, particularly the misidentification by MALDI-TOF-MS.
Diagnostic / clinical pearl
Clinicians should be aware of the potential for misidentification of Burkholderia pseudomallei as B. thailandensis, especially in non-endemic regions, and consider clinical history in diagnosis.
Why it matters
This case highlights the importance of using the correct laboratory software for accurate identification and the need for careful interpretation of antibiotic susceptibility testing results.
