Performance of Chagas Disease Genotyping Assay Evaluated

Chagas disease remains a significant public health issue infecting six to seven million people worldwide. The factors influencing the clinical heterogeneity of Chagas disease have not been elucidated, although it has been suggested that different clinical outcome may be associated with the genetic diversity of Trypanosoma cruzi isolates.

Immunoproteomics Identifies New Biomarkers for Crohn’s Disease

Using a new screening approach, a study aimed at developing a better blood test for Crohn’s disease (CD) successfully identified several antibodies that could serve as diagnostic markers. More...

Transplanted Microbes Alter Gut Function and Behavior

Transplantation of fecal microbiota from patients with irritable bowel syndrome (IBS) resulted in IBS-like changes in gut function as well as behavior in recipient mice. Such findings could facilitate development of improved diagnostics as well as effective treatments to replace current symptom-targeting treatments. More...

Portable Device Being Developed to Detect Zika at POC

A handheld diagnostic device may enable detection of Zika virus accurately, rapidly, and inexpensively in many settings, even at airports as it requires only a saliva sample. More...

Evidence Shows Nosocomial Infections Linked to Hospital Sink Bacteria

Investigators working with a unique hospital sink laboratory demonstrated that nosocomial infections, including those of multiple drug resistant organisms, are spread by bacterial colonies in the waste pipes that migrate up to the sink strainers where they are spread to the surface of the sink, faucets, and nearby counters.
