Hydroponic Lettuce Was Seen as Safe From Salmonella, Until an Outbreak

Her husband drove her to an emergency room, where she was erroneously diagnosed with viral gastritis. Back home, the diarrhea continued, causing her to rush to the bathroom as often as 15 times a day. “A couple of times, it felt like labor,” Ms. Hilliard said. “I was just screaming from the pain.” Her doctor […]

Engineered bacteria could help protect “good” gut microbes from antibiotics

Antibiotics are life-saving drugs, but they can also harm the beneficial microbes that live in the human gut. Following antibiotic treatment, some patients are at risk of developing inflammation or opportunistic infections such as Clostridiodes difficile. Indiscriminate use of antibiotics on gut microbes can also contribute to the spread of resistance to the drugs. In […]

Microbes and minerals may have set off Earth’s oxygenation

For the first 2 billion years of Earth’s history, there was barely any oxygen in the air. While some microbes were photosynthesizing by the latter part of this period, oxygen had not yet accumulated at levels that would impact the global biosphere. But somewhere around 2.3 billion years ago, this stable, low-oxygen equilibrium shifted, and […]

He Spent Decades Protecting Buffalo. A Microscopic Invader Threatens That Work.

Jeff Martin, who grew up on a buffalo ranch in Wisconsin and now studies the animals at South Dakota State University, said there was a link between the growing number of cases and the warming climate, which can cause stress for buffalo, weakening their immune systems and making them more susceptible to infections. The Northern […]

SMART researchers discover unique lysin capable of killing multidrug-resistant bacteria

Researchers from the Antimicrobial Resistance (AMR) Interdisciplinary Research Group at Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, alongside collaborators at Nanyang Technological University, have identified a novel phage lysin — Abp013 — that could be used as an alternative antimicrobial agent against two of the most deadly bacteria: Acinetobacter baumannii […]

Her IBS Was Misery. But What If She Actually Had Something Else?

Everything started in 1998 when she went to Mexico, she explained to Bonlie. She had a couple of days of diarrhea and had never felt the same since. Within weeks she developed a sensitivity to corn. Every time she ate it, she felt just awful. Then it was gluten. Then dairy. Then fats. Spicy foods […]

Protein structure offers clues to drug-resistance mechanism

MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria become resistant to multiple antibiotics. Using nuclear magnetic resonance (NMR) spectroscopy, the researchers were able to determine how the structure of […]

Predator interactions chiefly determine where Prochlorococcus thrive

Prochlorococcus are the smallest and most abundant photosynthesizing organisms on the planet. A single Prochlorococcus cell is dwarfed by a human red blood cell, yet globally the microbes number in the octillions and are responsible for a large fraction of the world’s oxygen production as they turn sunlight into energy. Prochlorococcus can be found in […]

Should You Get a Microbiome Test?

Despite how much scientists have learned in recent years, there remains a lot that we still don’t know about the thousands of different microbial species that can inhabit the gut. “The known unknowns of the microbiome are staggering: Approximately 20 percent of bacterial gene sequences have not been identified,” and the function of 40 percent […]

Are There Benefits to Drinking Kombucha?

Kombucha is a fermented food, much like cultured yogurt, cheese, kefir, kimchi and sauerkraut. Traditionally a carbonated drink with live micro-organisms, kombucha is made by brewing together sugar, black or green tea, liquid from a previous batch and the Scoby, short for symbiotic culture of bacteria and yeast (though its more popular nickname is “mother,” […]
