Melioidosis in a traveller from Thailand: case report.

A 42-year old Italian male with type 2 diabetes and HCV-related chronic hepatitis spent 6 months in Thailand. After his return in June 2002 he was admitted to the Infectious Diseases Unit of the Hospital of Livorno (Italy) because of fever, chest pain and skin abscesses in the legs. Chest X-rays and CT scan revealed multiple bilateral cavitary lesions in the lungs. Ultrasonography and CT scan showed numerous subcentimetric spleen abscesses. Burkholderia pseudomallei was isolated from the cutaneous lesions and sputum and thus melioidosis was diagnosed. A 6-week course of i.v. ceftazidime plus oral doxycycline was given during the acute phase of the illness. The in vitro susceptibility testing showed that long-term (20 weeks) antimicrobial therapy with doxycycline and moxifloxacin was required. Complete resolution of pulmonary and spleen lesions was obtained within 6 weeks of therapy and of cutaneous abscesses in 10 weeks. No significant side effects were noted during the follow-up period using this scheme of antimicrobial therapy.
