Detection of anti-Burkholderia pseudomallei antibodies in sera from melioidosis patients still represents a keystone in the confirmation of the clinical diagnosis, especially in non-endemic areas. An in-house assay was compared to lateral flow assays for the rapid detection of melioidosis-specific IgG or IgM. Employing 50 positive sera from patients and 200 negative sera from blood donors, sensitivity of the ELISA, the IgG and IgM assay were 84.0%, 90.0% and 84.0%, respectively. Specificity ranged from 98.0% (ELISA) to 99.5% (IgM assay). The application of the described diagnostic assays is a suitable method for the serodiagnosis of melioidosis in a non-endemic area.

, the causative agent of melioidosis can be responsible for a wide spectrum of clinical manifestations and heterogeneous prognoses, with a high mortality in the acute onset. We report a case of a deep abdominal abscess with sepsis secondary to melioidosis in a young farmer from a non-high-risk population. Emergency medical treatment was administered according to the detection of serum antibodies against Hcp1, the results of which provided etiological evidence of infection for the timely and properly antimicrobial therapy in the absence of direct evidence of melioidosis.

Melioidosis caused by Burkholderia pseudomallei causes significant morbidity and mortality in Southeast Asia and northern Australia. Clinical manifestations remain diverse, including localized skin infection, pneumonia, and chronic abscess formation. Culture remains the gold standard of diagnosis, with serology and antigen detection tests playing a role if culture is unfeasible.

Scrub typhus is a mite-borne disease caused by a Gram-negative obligately intracellular bacillus, . The disease is endemic in the Asia-Australia-Pacific region, including Thailand. Scrub typhus generally manifests as acute undifferentiated febrile fever along with myalgia, rash, and lymphadenopathy.

Background: The accurate and rapid diagnosis of melioidosis is challenging. Several serological approaches have been developed using recombinant antigens to improve the diagnostic indices of serological tests for melioidosis.
Methods: Fusion proteins from Burkholderia pseudomallei (rGroEL-FLAG300) were evaluated as a potential target antigen for melioidosis antibodies.
