A new bacterial blueprint to aid in the war on antibiotic resistance
A team of scientists from around the globe, including those from Trinity College Dublin, has gained high-res structural insights into a key bacterial enzyme that may help chemists design new drugs to inhibit it and thus suppress disease-causing bacte.....»»
Photodynamic action weakens resistance to antibiotics in bacteria that attack airways
The development of antibiotics to combat multidrug-resistant bacteria, especially those that infect the airways, has been increasingly tricky, and some scientists have opted to try to weaken the bacteria so that the available therapeutic substances a.....»»
New method paves the way for new antibiotics
Norwegian University of Science and Technology (NTNU) researchers have developed a promising antibiotic candidate against MRSA. Behind the discovery lies a methodology that may be important in the fight against antimicrobial resistance......»»
Novel bacteria identification methods might help speed up disease diagnosis
Pseudomonas aeruginosa is a bacterial strain that can be responsible for several human diseases. The most serious include malignant external otitis, endophthalmitis, endocarditis, meningitis, pneumonia, and septicemia......»»
Study shows diverse gut bacteria communities protect against harmful pathogens by nutrient blocking
The human gut is home to hundreds of different bacterial species collectively known as the gut microbiome. A major health benefit these provide is to protect the gut against invading pathogens (disease-causing microorganisms) that could cause harmful.....»»
Cockroaches can transmit antimicrobial resistance genes between groups
A new paper describes a study of antimicrobial resistance (AMR) transmission among cockroaches, with implications for AMR transmission in humans. The study was published in mSystems......»»
New study eyes nutrition-rich chia seed for potential to improve human health
Oregon State University scientists have sequenced the chia genome and in doing so provided a blueprint for future research that capitalizes on the nutritional and human health benefits of the plant......»»
Civilian attacks likely to strengthen Ukrainian resistance, say researchers
During the all-out invasion of Ukraine, Russia has deliberately chosen civilian targets, such as apartment buildings, presumably with the goal of deterring Ukrainian resistance. But does such terror deter or, in contrast, motivate resistance among or.....»»
Research reveals a rare enzyme role change with bacterial defense system assembly
Scientists have revealed a never-before-seen phenomenon in a protein: Alone, the enzyme processes DNA and RNA but, when bound to another protein as part of a defense system, interacts with a completely different type of compound to help bacteria comm.....»»
Review examines machine learning concepts for microbiologists
In a review in Nature Reviews Microbiology, Professor Levi Waldron and colleagues highlight the increasing importance of machine learning in microbiology, where it is used for tasks such as predicting antibiotic resistance and associating human micro.....»»
Nanomaterial with "light switch" kills Gram-negative or Gram-positive bacteria
Health care-associated infections are a common problem in suppurating wound care, as is the rise in multi-drug resistant bacteria. In order to effectively and selectively combat bacterial infections, a team of researchers has developed a bactericidal.....»»
New study finds that male pathology in songbirds drives avian epidemic dynamics
New findings by biological sciences researchers at the University of Arkansas indicate that males play an outsized role in both the infection rate and spread of the avian bacterial pathogen Mycoplasma gallisepticum, a common cause of conjunctivitis i.....»»
New method for identifying bacteria more easily
Far too many antibiotics are used around the world. As a result, bacteria are becoming resistant to these drugs. Curing bacterial diseases is becoming more difficult than before because antibiotics are perhaps our foremost weapons in the fight agains.....»»
Study show extracellular vesicles can also deliver messages from non-human cells
Messenger bubbles produced by human cells can pick up bacterial products and deliver them to other cells, University of Connecticut researchers report in the Nov. 16 issue of Nature Cell Biology. The discovery may explain a key mechanism by which ba.....»»
Unlocking long-term genetic memory: Dormant bacterial spores offer key insights into evolutionary survival strategies
A recent study spearheaded by Prof. Sigal Ben Yehuda and her team at Hebrew University has unveiled a captivating facet of bacterial dormancy. Their research illuminates the mechanism through which dormant bacterial spores uphold and activate an endu.....»»
Pocket-sized DNA sequencers track malaria drug resistance in Ghana in near real-time
Scientists have developed a technique to rapidly and reliably detect genetic changes in malaria parasites in Ghana, using just a gaming laptop and portable MinION sequencer from Oxford Nanopore......»»
Researchers untangle the relationships between bacterial languages
A combination of machine learning and lab experiments has given researchers a peek into the different languages bacteria use to communicate. Understanding how bacteria communicate—and when they can't—has implications for treating drug-resistant b.....»»
Study provides fresh insights into antibiotic resistance, fitness landscapes
E. coli bacteria may be far more capable of evolving antibiotic resistance than scientists previously thought, according to a new study published in Science on November 24......»»
Clues to mysterious new sickness affecting dogs
A new type of bacterial infection could be the culprit behind a mysterious canine respiratory illness that has been infecting dogs from coast to coast, New Hampshire researchers say......»»
Researchers identify "unicorn" defense mechanism that protects bacteria from antibiotics
Researchers at McMaster University have discovered unique characteristics of a mechanism used by bacteria to resist an important class of antibiotics. The new research, published in Nature Chemical Biology, shows that resistance to aminoglycoside dru.....»»
Chlorine disinfectant is no more effective than water at killing off hospital superbug, new study shows
One of the primary chlorine disinfectants currently being used to clean hospital scrubs and surfaces does not kill off the most common cause of antibiotic-associated sickness in health care settings globally, according to a new study......»»
