Prevalence of extended-spectrum β-lactamase-producing Enterobacterales in edible ice in Thailand.

Background: The presence of antimicrobial-resistant (AMR) bacteria in edible ice in tropical countries is largely unknown.

Methods: We evaluate the presence of extended-spectrum β-lactamase (ESBL)-producing Enterobacterales in 100 edible ice samples from drink carts in 20 markets in four provinces (five markets/province) in Thailand. Ten samples of commercially sold edible ice in sealed packages were tested as controls.

Melioidosis in Patients with COVID-19 Exposed to Contaminated Tap Water, Thailand, 2021.

In September 2021, a total of 25 patients diagnosed with COVID-19 developed acute melioidosis after (median 7 days) admission to a COVID-19 field hospital in Thailand. Eight nonpotable tap water samples and 6 soil samples were culture-positive for Burkholderia pseudomallei. Genomic analysis suggested contaminated tap water as the likely cause of illness.

Plasma Metabolomics Reveals Distinct Biological and Diagnostic Signatures for Melioidosis.

The global burden of sepsis is greatest in low-resource settings. Melioidosis, infection with the gram-negative bacterium , is a frequent cause of fatal sepsis in endemic tropical regions such as Southeast Asia. To investigate whether plasma metabolomics would identify biological pathways specific to melioidosis and yield clinically meaningful biomarkers.

Sensitivity and specificity of DPP® Fever Panel II Asia in the diagnosis of malaria, dengue and melioidosis.

Rapid diagnostic tests (RDTs) that can facilitate the diagnosis of a panel of tropical infectious diseases are critically needed. DPP® Fever Panel II Asia is a multiplex lateral flow immunoassay comprising antigen and IgM panels for the diagnosis of pathogens that commonly cause febrile illness in Southeast Asia. Accuracy of DPP® Fever Panel II Asia has not been evaluated in clinical studies.
