Fatal Fungal Infection Has Unique Growth Patterns

The multidrug-resistant yeast Candida auris, which has caused fatal infections in some hospitalized patients, has at least two different growth patterns and some of its strains are as capable of causing disease as the most invasive type of yeast called Candida albicans. More...

Miniaturized Clinical Test Rapidly Detects Antibiotic Resistance

A new microfluidic concept for multi-analyte testing in a dipstick format, termed “Lab-on-a-Stick”, that combines the simplicity of dipstick tests with the high performance of microfluidic devices has been developed. More...

Innate Immune Sensor of Microbial Proteolysis Revealed

The human immune system can quickly recognize and respond to bacterial infections, but sometimes this reaction can become skewed, leading to autoimmune diseases such as rheumatoid arthritis. In this case, a person's own immune system attacks "self" proteins instead of just foreign invaders. More...
