NewsGut parasites identified from feces of ancient Mexican people
DNA within dried feces dating from more than 1,000 years ago provides valuable insights into the pathogens that plagued ancient Mexican peoples. A study identified genetic signatures of a diverse array of gut parasites, many of which have never before been detected in ancient feces.

NewsDangerous E. coli strain blocks gut’s defense mechanism to spread infection
When harmful bacteria invade through the digestive tract, gut cells usually fight back by pushing infected cells out of the body to stop the infection from spreading. Scientists have discovered that a dangerous strain of E. coli can block gut this defense, allowing the bacteria to spread more easily.

NewsDusty air is rewriting your lung microbiome
Dust from California’s drying Salton Sea doesn’t just smell bad. Scientists found that inhalation of airborne dust collected close to the shallow, landlocked lake alters both the microbial landscape and immune responses in mice that were otherwise healthy.

NewsReport explores health, economic, and societal benefits of vaccination
A new report provides evidence on the advantages of immunization for individual and population health, economic outcomes, and societal well-being. Studies show that every $1 spent on childhood vaccines saves about $11 in avoided medical costs and preserved productivity.

NewsScientists develop a way to track donor bacteria after fecal microbiota transplants
Researchers have developed a new technology to track beneficial bacteria for up to 5 years after fecal microbiota transplants (FMT). The method allows scientists to distinguish even closely related bacterial strains and identify each one’s unique genetic “fingerprint.”

NewsNew hope for cats with eye infections: Study finds common cold sore cream safe and effective for feline use
A common human cold sore cream may soon help cats with painful eye infections: researchers found that 1% penciclovir cream (Fenlips®), when applied to cats’ eyes, was safe, well-tolerated, and maintained antiviral levels for over eight hours.

NewsAre there living microbes on Mars? Check the ice, researchers say
By recreating Mars-like conditions in the lab, researchers demonstrated that fragments of the molecules that make up proteins in E. coli bacteria, if present in Mars’ permafrost and ice caps, could remain intact for over 50 million years.

NewsStudy reveals how bacteria in tumors drive treatment resistance in cancer
Researchers have uncovered a previously unknown way for microbes within tumors to contribute to treatment resistance in certain cancers. The study finds these microbes push cancer cells into a reversible resting state, allowing them to become resistant to certain chemotherapies.
