Here’s How Bad Antibiotic Resistance Has Gotten Over the Past 20 Years

Written by Julia Ries on October 21, 2019

Over the past decade, antibiotic resistance has emerged as one of the greatest public health threatsTrusted Source.

AntibioticsTrusted Source have been used to prevent and treat bacterial infections since the 1940s when doctors first discovered the powerful drugs could save people’s lives.

But in recent decades overuse and misuse has resulted in infectious bacteria becoming resistantTrusted Source to these common drugs. Today, researchers have more details on just how severe antibiotic resistance has become and found evidence that we’ve reached a frightening new milestone.

New research published in the journal Antimicrobial Agents and Chemotherapy today discovered that resistance to one of the last resort drugs used to treat extremely drug-resistant Pseudomonas aeruginosa can develop a lot more quickly than we originally thought.


Fewer Sick Kids When Water Pump Gets Chlorine Dispenser

AUGUST 19TH, 2019 POSTED BY ROB JORDAN-STANFORD on Futurity.org

Installing an automatic chlorine dispenser at shared community water points reduces rates of diarrhea in children, a new study in Bangladesh shows.

Diarrhea kills a child under the age of five every minute on average. Diarrheal disease, the second leading cause of death for children globally, could become even more difficult to control as poor urban areas with limited clean water access expand.

Researchers call the new dispenser, described in The Lancet Global Health, an improvement over other purification strategies.


Researchers Identify Gut Microbes to Help Malnourished Kids Recover

Calories aren’t enough to correct malnourishment, but eating foods that spur specific microbes to grow in the gut can.

Jul 12, 2019 | ASHLEY P. TAYLOR

Even once they have enough to eat, kids that have suffered from malnutrition do not grow and develop as well as kids that have always had healthy foods to eat. Two studies published today (July 12) in Science identify differences between the microbiomes of malnourished and healthy kids as well as a combination of foods that, both in animals and in a proof-of-principle study in children, helps shift the microbiome toward a healthier state.

Providing food aid tailored to microbiome health “could be a key to new strategies for improving global public health and human potential,” David Relman, a microbiologist at Stanford University School of Medicine in Palo Alto, California, who was not involved in either study, tells Science.


Viruses act as decoys, study finds, helping bacteria evade the immune system

By ERIC BOODMAN @ericboodman

MARCH 28, 2019

These viruses weren’t supposed to affect humans. They were supposed to ride along inside bacteria — unobtrusive hitchhikers taking advantage of another microbe’s machinery. But that wasn’t what Dr. Paul Bollyky and his colleagues saw in their lab dishes three or four years ago. The viruses seemed to be changing the behavior of human immune cells. Instead of gobbling up bacteria as they normally did, white blood cells just sat there.

“They basically don’t eat anything. They don’t move around much either,” said Bollyky, an immunologist and infectious disease specialist at Stanford University. “They would just ignore … the bacteria that were in the dish with them.”

Now, with a paper published Thursday in Science, what began as a chance observation has yielded a startling window into the inner lives of infections — one in which viruses tag-team with bacteria to trick the immune system by providing a decoy. Bollyky describes it as having someone trip the fire alarm so that the rest of the team can pull off a robbery in the chaos that ensues.


Scientists: US military program could be seen as bioweapon

By  Candice Choi and Seth Borenstein - October 4, 2018

NEW YORK (AP) — A research arm of the U.S. military is exploring the possibility of deploying insects to make plants more resilient by altering their genes. Some experts say the work may be seen as a potential biological weapon.

In an opinion paper published Thursday in the journal Science, the authors say the U.S. needs to provide greater justification for the peace-time purpose of its Insect Allies project to avoid being perceived as hostile to other countries. Other experts expressed ethical and security concerns with the research, which seeks to transmit protective traits to crops already growing in the field.
