Traveler's Diarrhea Among Soldiers Linked to Gut Microbiome Changes

Travelers’ diarrhea (TD) is the most prevalent illness encountered by deployed military personnel and has a major impact on military operations, from reduced job performance to lost duty days. Frequently, the etiology of TD is unknown and, with underreporting of cases, it is difficult to accurately assess its impact. More...

Loop-Mediated Isothermal Amplification-Assay Rapidly Diagnoses COVID-19

The SARS-CoV-2 (COVID-19) pandemic of 2020 has resulted in unparalleled requirements for RNA extraction kits and enzymes required for virus detection, leading to global shortages. This has necessitated the exploration of alternative diagnostic options to alleviate supply chain issues. More...

Serological Dipstick Assay Developed for Melioidosis

The Gram-negative environmental pathogen Burkholderia pseudomallei, causes the severe disease melioidosis. It is highly endemic in southeast Asia and northern Australia, but recent studies suggest that it is also present in many other parts of the world where it is severely underreported. More...

Lipocalin 2 Proposed as Biomarker for Bacterial Meningitis

Central nervous system (CNS) infections cause significant mortality and morbidity worldwide. Common CNS infections include bacterial meningitis (BM) other than tuberculosis, viral encephalitis, tuberculous meningitis (TBM) and cryptococcal meningitis, but there are more than 100 documented infectious causes of CNS infections. More...

Eosinophil Count Provides Diagnostic Information for COVID-19

Early diagnosis of coronavirus disease 2019 (COVID-19) and patient isolation are important for both individual patient care and disease containment. The diagnosis is confirmed by testing for the presence of nasopharyngeal viral RNA with a polymerase chain reaction assay, which has limited availability, variable turnaround time, and a high false-negative rate. More...
