Microbiologist Aimee Shen at Tufts University School of Medicine is one of 12 new recipients nationwide of the Burroughs Wellcome Fund 2018 Investigators in the Pathogenesis of Infectious Disease (PATH) award for her research on Clostridium difficile.
With microbial resistance to antibiotics growing into a major global health crisis, researchers at University of California San Diego School of Medicine, in collaboration with national research institutions and private industry, are leveraging hard-won expertise to exploit a natural viral enemy of pathogenic bacteria, creating North America’s first Center for Innovative Phage Applications and Therapeutics (IPATH).
FAU’s Harbor Branch houses more than 1,000 strains of actinobacteria, one of the most prolific microbial groups for the production of natural products. Derived from sea sponges and other macro-organisms, several strains were identified for their potent antifungal activity, for anti-MRSA activity, and for both antifungal and antibacterial activities. A key finding was the identification of a strain that produced metabolites that are more potent than the bacterial antibiotic, vancomycin, against C. difficile.
A new federally funded center of excellence led by Iowa State University scientists will analyze various structures and mechanisms in the swine genome with the goal of allowing pork producers to predict with greater accuracy the traits in their herds. The institute will include personnel at Iowa State, Michigan State, The University of California at Davis, and the USDA Agriculture Research Service.
Antimicrobial resistance continues to increase, and antimicrobial stewardship programs are developing plans to report antimicrobial use in order to reduce and optimize the use of antibiotics.
Researchers at Indiana University have made the first direct observation of how bacteria use appendages thousands of times thinner than a human hair to absorb DNA in the environment. The work could help advance efforts stop antibiotic resistant bacteria.
During 325 observations, researchers at the University of Utah and University of Michigan identified 283 protocol violations, which could increase the risk of self-contamination of health care personnel and transmission of antibiotic-resistant organisms to patients.
Results from a new clinical study have confirmed the safety and tolerability of using bacteria-specific viruses known as bacteriophages to eliminate disease-causing bacteria in the gut.

An international team of researchers has found a new way to investigate how tuberculosis bacteria inactivate an important family of antibiotics: They watched the process in action for the first time using an X-ray free-electron laser, or XFEL.
A new study led by David Broniatowski, an assistant professor in the George Washington University’s department of engineering management and systems engineering, finds the “Why not take a risk?” mentality is widespread among patients and medical care providers.
Engineers at the University of California San Diego have developed tiny ultrasound-powered robots that can swim through blood, removing harmful bacteria along with the toxins they produce. These proof-of-concept nanorobots could one day offer a safe and efficient way to detoxify and decontaminate biological fluids.
Scientists in Madagascar have for the first time performed DNA sequencing in-country using novel, portable technology to rapidly identify the bacteria responsible for tuberculosis (TB) and its drug resistance profile.
Most of what we know today about deadly bacteria such as Pseudomonas aeruginosa was obtained from studies done in laboratory settings. Research reported May 14 in the journal Proceedings of the National Academy of Sciences shows that this laboratory-based information may have important limits for predicting how these bugs behave once they’ve invaded humans.
Drug-resistant staph infections continue to be deadlier than those that are not resistant and treatable with traditional antibiotics, but treatment costs surprisingly are the same or slightly less, a new national analysis shows.

Epilepsy patients who have not responded to standard drug treatments may benefit from a new therapy that delivers high frequency bursts of electrical stimulation, called microbursts, to the brain. Rush University Medical Center in Chicago is the first health care provider in the world to provide this treatment, known as microburst vagus nerve stimulation.
Antibiotic-resistant Acinetobacter baumannii infections, one of the most common hospital-acquired infections in children across the United States, are on the rise, according to results of a recent study published in the Journal of the Pediatric Infectious Diseases Society on March 22.
UCLA Gram negative F. nucleatum-induced host-generated tsRNA inhibits the growth of F. nucleatum (top row) but not Streptococcus mitis (bottom row). A new UCLA-led study provides clear evidence that cellular messengers in saliva may be able to regulate the growth of oral bacteria responsible for diseases, such as periodontitis and meningitis.
