POC Tests Evaluated for Filarial Antigenemia

Lymphatic filariasis (LF) is a major neglected tropical disease (NTD) that has been targeted for elimination by 2020. The Global Programme to Eliminate Lymphatic Filariasis (GPELF, launched in 2000) uses repeated rounds of mass drug administration (MDA) with antifilarial drugs to interrupt transmission of the parasite.

Immunocompromised Patients at Risk for Blastomycosis

Most invasive fungal infections in immunocompromised patients are caused by Zygomycetes, Aspergillus, and Candida, but literature about Blastomyces infection in immunocompromised patients has been sparse. More...

Paper-Based TB Test Could Increase Diagnoses Worldwide

In resource-limited areas, equipment requirements and long wait times for results are obstacles to early diagnosis and treatment of tuberculosis (TB). To tackle this problem, scientists have developed a rapid colorimetric TB assay using gold nanoparticles on a paper-based device than enables results to be read with a smartphone. More...

Checklist Developed for Early Identification of Infants with SCID

Poor recognition of severe combined immune deficiency (SCID) syndrome by front-line doctors is leading to delays in diagnosis. A new testing regime aims to make diagnosis faster so that more infants with SCID, a “bubble-baby disease”, can receive life-saving treatment in time. More...

IBS Colon Reacts Differently to Bacteria

Irritable bowel syndrome disturbs bowel function and the condition leads to repeated episodes of abdominal pain, and usually gives rise to constipation or diarrhea. Around 10% of people in Sweden suffer from IBS, and it is twice as common among women as among men. More...

Molecular Test Detects Chagas in Blood Donors

The most prevalent parasitic infection in Latin America causes Chagas’ disease. Diagnosis is based on serologic tests because direct detection of Trypanosoma cruzi is very difficult beyond its brief acute phase. More...

Child Throat Bacteria Also Found in Joint Infections

Using sensitive diagnostics, researchers have found that the presence of the Kingella kingae in children's throats was strongly linked to bone and joint infection with the same bacterium. More...
