Infectious-disease specialists at UT Southwestern Medical Center have demonstrated that a cannibalistic process in cells plays a key role in limiting Salmonella infection.
Salmonella, the causative agent of salmonellosis, causes many of the intestinal infections and food-related illnesses rep... Read More
A new oral vaccine against sylvatic plague is showing significant promise in the laboratory as a way to protect prairie dogs and may eventually protect endangered black-footed ferrets who now get the disease by eating infected prairie dogs, according to results by a USGS researcher at the USGS N...

With China moving to control an outbreak of pneumonic plague, it's worth noting that the disease doesn't occur only in places for which Americans need a passport to visit. In fact, Los Angeles has dubious bragging rights to the United States' most recent rat-borne epidemic.
Here's a review of... Read More

Certainly there is strength in numbers, but only if those numbers can effectively communicate with one another. Now, a new study finds that administration of a novel small molecule which effectively disrupts a key bacterial communication process protects an animal host from infection. The resear... Read More
