Fungal Infection Identified by Pathogen Detection Array Technology

Patients who are undergoing treatment for diseases such as cancer often face the added challenge of a compromised immune system, which can be challenging to both of their condition and the drugs used to treat it, leaving them vulnerable to various opportunistic infections.  More...

Rapid Immunochromatographic Tests Evaluated for Novel Norovirus

A worldwide spread is conceivable as a novel Norovirus emerged in Asia in the winter of 2014/15 and Norovirus diagnostic assays need to be evaluated to investigate if they adequately detect this emerging genotype.  More...

Fluorescence Microscopy Technique Rapidly Determines Antibiotic Susceptibility

A recently developed diagnostic method that does not rely on culture growth or knowledge of the genes that convey resistance is based on quantitative fluorescence microscopy and enables the rapid determination of the antibiotic susceptibility of Staphylococcus aureus isolates.  More...

Immunochromatographic Test Evaluated to Diagnose Schistosomiasis

The Kato-Katz stool smear is the standard test for the diagnosis of Schistosoma mansoni infection but suffers from low sensitivity when infections intensities are moderate to low and therefore, misdiagnosed individuals remain untreated and contribute to the disease transmission.  More...
