UAB researchers awarded grant to study a vaccine for gonorrhea

University of Alabama at Birmingham researchers have been awarded a three-year contract with a total potential amount of $10 million to study the efficacy of the vaccine Bexsero - already licensed to prevent meningitis - in protecting vulnerable populations from infection with the bacteria that causes gonorrhea.

Study uses baker's yeast to show how genes interact to influence a surprising cellular outcome

Most diseases are complex--caused by faults in multiple genes--but studying how combinations of different genetic variants affect cellular traits is challenging.

Lifestyle of bacteria determines how they evolve antibiotic resistance

How bacteria live -- whether as independent cells or in a communal biofilm -- determines how they evolve antibiotic resistance, which could lead to more personalized approaches to antimicrobial therapy and infection control.

Half the drugs in use damage gut bacteria, says new study

A startling presentation at UEG Week 2019, in Barcelona, reveals that the gut microbiome is at high risk for damage each time we use a drug from one or more of 18 commonly used groups. The effects may range from changes in the relative proportions of different beneficial and potentially harmful species to alterations in the cellular metabolism of the bacteria themselves.

Scientists take new step toward the goal of growing cell-based meat for human consumption

A team of Tufts University-led researchers exploring the development of cultured meat found that the addition of the iron-carrying protein myoglobin improves the growth, texture and color of bovine muscle grown from cells in culture.

E. coli bacteria study may provide clues about drug resistance

Swapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study published in the journal eLife.

Antibiotic resistance doubles in just two decades

Antibiotic resistance poses a grave challenge to many previously curable infectious diseases. At present, antibiotic resistance is proving to increase at a much faster rate compared to the development of new therapies.

Discovery about DNA-reeling bacteria can help inform strategies to stop bacterial infection

A new study from Indiana University has revealed a previously unknown role a protein plays in helping bacteria reel in DNA in their environment -- like a fisherman pulling up a catch from the ocean.

UA researcher focuses on preventing health-care-associated infections

On any given day in the United States, about 1 in 31 hospital patients has at least one health-care-associated infection, according to the Centers for Disease Control and Prevention.

Nanomeshes could be effective drug delivery system for antibiotics

The fight against global antibiotic resistance has taken a major step forward with scientists discovering a concept for fabricating nanomeshes as an effective drug delivery system for antibiotics.

Low-dose exposure to antibiotics can have major impacts on gut bacteria

An antibiotic commonly found at low concentrations in the environment can have major impacts on gut bacteria, report researchers at the University of Oregon.

A Lego-like approach to enhance nature's own ability to attack bacteria

The Centers for Disease Control and Prevention considers antibiotic resistance one of the most urgent public health threats, one that affects communities worldwide. The ramifications of bacteria's ability to become resistant to antibiotics can be seen in hospitals, public places, our food supply, and our water.

Study shows antibiotic resistance in livestock has almost tripled since 2000

The growing appetite for animal protein in developing countries has resulted in a smorgasbord of antibiotic consumption for livestock that has nearly tripled the occurrence of antibiotic resistance in disease-causing bacteria easily transmitted from animals to humans, according to a recent report in the journal Science.
