Immunochromatographic Test Developed for Visceral Leishmaniasis

The available diagnostic tests for visceral leishmaniasis are either invasive and require considerable expertise such as the parasitological demonstration of the parasite in tissue smears or unable to distinguish between past and active infection as in serological methods.  More...

Rapid Ebola Test Validated in Field Trials

At present, diagnosis of Ebolavirus disease requires transport of venipuncture blood to field biocontainment laboratories for testing by real-time reverse transcription polymerase chain reaction (RT-PCR), resulting in delays that complicate patient care and infection control efforts.  More...

Biosensor-Based Rapid Urine Test Detects Urogenital Schistosomiasis

In infrastructure-limited regions, point-of-care molecular diagnostics hold the potential to transform the management of infectious diseases such as schistosomiasis that carry significant long-term morbidity if left undiagnosed.  More...

Recent Mutations Responsible for Plague Bacteria's Virulence

A team of molecular microbiologists has found that acquisition of single protein early in its existence enabled the plague bacterium Yersinia pestis to invade lung tissue, but that it required later mutations of this gene to enable the organism to rapidly spread to the lymph nodes and cause the bubonic form of the disease.  More...
