Gut Microbiome Pretreatment Predicts Chemotherapy-Related Bloodstream Infection

Bacteria are thought to enter the bloodstream through intestinal lesions due to chemotherapy-induced inflammation of the membrane lining the digestive tract. Once the infection begins, patients' own immune systems are depleted and are often unable to fight off the pathogens and antibiotics are often ineffective. More...

HPV Infection Identified In Self-Collected Vaginal Swabs

High risk, potentially cancer causing human papillomavirus infections (HPV) are common among women in the developing world, but self-sampling with vaginal swabs may provide materials that screen as accurately as the more labor-intensive approach using cervical samples obtained by clinicians. More...

Chemical Sensor Rapidly Detects Fungal Infections

An elevated concentration of D-arabitol, a simple sugar alcohol, in urine, especially compared to that of L-arabitol or creatinine, is indicative of a fungal infection, which can become deadly. More...

Palm-Sized Device Quickly Detects Ebola Virus

The gold standard method for identifying the Ebola virus in a blood sample requires packaging samples in cooled containers and sending them to specialized laboratories, often far away from where patients live. More...

Combining Two Diagnostic Tests Drastically Reduces Cancer Miss Rates

The Papanicolaou (Pap) test is recommended for women between 21 and 65 years old as a screening test for cervical cancer. Women 30 and older who are negative on co-testing may wait as long as five years for their next testing, but physicians still recommend annual examinations. More...

CRISPR-based Technology Enables High-Resolution Zika Detection On Low-Cost Paper Discs

Building off their earlier innovative development in “programmable diagnostics”, researchers on an international, multi-institutional team recently joined efforts to quickly prototype their low-cost rapid test with the goal that it could soon be used to screen samples (blood, urine, or saliva) for Zika virus and strain identification. More...

Microbiologists Display Prototype of Rapid Bacteriological Test Device

A prototype rapid diagnostic device was shown in a proof-of-concept study to identify pathogenic microorganisms with accuracy comparable to that of bacterial culture but with much shorter turnaround time. More...
