Follow Your Nose: Towards More Ecological Antimicrobial Therapies

The remarkable transformation in the control of in­fec­tious diseases by antibiotics is one of the glorious stories in microbiology. But now, almost inseparable from their discovery and application, is its nasty sequel, the rapid evolution of antibiotic resistance. We continually read reports of... Read More

Seeking understanding of the bacterial sec system

How do bacterial proteins destined for export move from inside to outside the cell? As mBiosphere readers may know, there are a number of secretion systems that bacteria use to move materials from inside the cell to outside the cell. Some of these systems, such as the Sec secretion system, are c... Read More

Quorum Sensing for the Mutes

It is (almost boringly) obvious that cell-to-cell com­mu­ni­ca­tion is vital in multicellular organisms. To function pro­per­ly, all cells in a tissue have to know – and let their neigh­bors know – where exactly they are, which tasks they're performing right now, when it's time to dif­fer­en­ti­...

A bacterial role in breast cancer development and prevention

Microbial infection is implicated in an ever-growing number of types of cancer. Adding to the already long list of microbial-associated cancers, an increasing body of evidence suggests breast cancer may also be associated with a specific microbial milieu.
