Persistent infection in infant reveals mutation that helps bacteria tolerate antibiotic therapy

The quest to understand a prolonged infection in an infant being treated for leukemia has led to the St. Jude Children's Research Hospital discovery of a mutation that allows bacteria to tolerate normally effective antibiotic therapy. The report appears today in the scientific journal mBio.

Study examines how ApoE gene may function differently in infectious environment

You've likely heard about being in the right place at the wrong time, but what about having the right genes in the wrong environment? In other words, could a genetic mutation (or allele) that puts populations at risk for illnesses in one environmental setting manifest itself in positive ways in a different setting?

Genomic sequencing reveals new insights into major shigellosis outbreaks in California

In a study that could have significant impact on how disease outbreaks are managed, researchers at UC Davis and the California Department of Public Health have sequenced and analyzed genomes from Shigella sonnei (S. sonnei) bacteria associated with major shigellosis outbreaks in California in 2014 and 2015.

Bacteriophages may play key role in acquisition and mobilization of antibiotic resistance genes

Scientists at the Catalan Institute for Water Research have carried out a comprehensive analysis of several viromes from different habitats to explore whether bacteriophages (viruses that infect bacteria) harbor antibiotic resistance genes.

Overexpression of nerve growth factor drives gastric tumorigenesis in mice

Gastric tumors are started by specialized cells in the stomach that signal nerves to make more acetylcholine, according to a study in mice.

New erectile dysfunction treatment uses high-frequency acoustical waves

Statistically speaking, 50% of all men, have experienced erectile dysfunction (ED) at some time or another, and the chance of developing ED increases as you age. The medical management of ED has evolved greatly over the past several decades.

Researchers identify attractive drug candidate to target glioma tumors

In a paper published today in Cancer Research, researchers: 1) identify a biomarker enzyme associated with aggressive glioma brain tumors, 2) reveal the regulatory mechanism for that enzyme, and 3) demonstrate potent efficacy, using a mouse model of glioma, for a small molecule inhibitor they have developed.

Common bacterium that causes gum infections may trigger rheumatoid arthritis

Investigators at Johns Hopkins report they have new evidence that a bacterium known to cause chronic inflammatory gum infections also triggers the inflammatory "autoimmune" response characteristic of chronic, joint-destroying rheumatoid arthritis (RA).

Human migration study reveals new insights into cancer metastasis

What could cancer cells and drug-resistant bacteria possibly have in common with Stone Age settlers of the Americas? They're all migratory, and at one time or other, each finds the going a bit easier in a specific direction.
