Melioidosis clinically unresponsive to meropenem in a traveller returning from Thailand.

Burkholderia pseudomallei can cause severe systemic infection with involvement of multiple organs and abscess formation. Carbapenems are considered superior to ceftazidime in severe cases. We here report a case of Melioidosis in a previously healthy 57-year-old traveller. Despite in vitro testing confirming susceptibility of the isolate for meropenem, the patient's clinical condition did not improve during seven days of meropenem treatment. After changing the treatment regimen to high-dose ceftazidime, the patient's clinical condition and laboratory parameters rapidly improved. Thus, we here report a rare case of Melioidosis clinically unresponsive to meropenem.
