Penn researchers use iron-containing nanoparticles to reduce plaque and prevent tooth decay

Penn researchers use iron-containing nanoparticles to reduce plaque and prevent tooth decay

The bacteria that live in dental plaque and contribute to tooth decay often resist traditional antimicrobial treatment, as they can "hide" within a sticky biofilm matrix, a glue-like polymer scaffold. [More]
Study identifies key risk factors involved in patient-to-patient transmission of drug-resistant bacteria

Study identifies key risk factors involved in patient-to-patient transmission of drug-resistant bacteria

Three key factors increase the risk for patient-to-patient transmission of an extremely drug-resistant bacteria known as CP-CRE, according to a new study published today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. [More]
Researchers develop new microneedle system to painlessly monitor drugs in bloodstream

Researchers develop new microneedle system to painlessly monitor drugs in bloodstream

Researchers at the University of British Columbia and the Paul Scherrer Institut in Switzerland have created a microneedle drug monitoring system that could one day replace costly, invasive blood draws and improve patient comfort. [More]
Combinations of three antibiotics could help combat drug-resistant bacterial infections

Combinations of three antibiotics could help combat drug-resistant bacterial infections

Each year, approximately 700,000 people die from drug-resistant bacterial infections. A study by UCLA life scientists could be a major step toward combating drug-resistant infections. [More]
Long-term antibiotic treatment slows progression of Alzheimer's disease through changes in gut bacteria

Long-term antibiotic treatment slows progression of Alzheimer's disease through changes in gut bacteria

Long-term treatment with broad spectrum antibiotics decreased levels of amyloid plaques, a hallmark of Alzheimer's disease, and activated inflammatory microglial cells in the brains of mice in a new study by neuroscientists from the University of Chicago. [More]
Scientists develop new optical fiber-based probe for brain temperature measurements

Scientists develop new optical fiber-based probe for brain temperature measurements

The brain is the most temperature-sensitive organ in the body. Even small deviations in brain temperature are capable of producing profound effects--including behavioral changes, cell toxicity, and neuronal cell death. The problem faced by researchers and clinicians is how to measure and understand the [More]
Study develops new methodology to analyse genetic bases of pathogenic bacteria

Study develops new methodology to analyse genetic bases of pathogenic bacteria

The study has developed a pioneering methodology to analyse the genetic bases of pathogenic bacteria and can be used to identify therapeutic targets in order to develop new antimicrobial agents. [More]
Researchers find dangerous antibiotic-resistant bacteria in wastewater from broken sewer lines

Researchers find dangerous antibiotic-resistant bacteria in wastewater from broken sewer lines

University of South Florida researchers investigating the aftermath of a September, 2014 sewer line break in St. Petersburg, Florida, have found dangerous antibiotic-resistant bacteria in the untreated wastewater that gushed into neighborhoods and into Boca Ciega Bay at a rate of 250 to 500 gallons per minute.

Antibiotic usage, infections may contribute to manic episodes in people with mental disorders

Antibiotic usage, infections may contribute to manic episodes in people with mental disorders

In research using patient medical records, investigators from Johns Hopkins and Sheppard Pratt Health System report that people with serious mental disorders who were hospitalized for mania were more likely to be on antibiotics to treat active infections than a group of people without a mental disorder.

Tourists returning from India import multidrug-resistant superbugs

Tourists returning from India import multidrug-resistant superbugs

Many tourists returning from India were found colonized with multidrug-resistant superbugs. Microbiologists at the Institute for Infectious Diseases of the University of Bern, Switzerland, also isolated a strain possessing a gene which can make these life-threatening bacteria resistant to the last active antibiotic option.

Scientists detect gut bacteria in deepest reaches of failing lungs

Scientists detect gut bacteria in deepest reaches of failing lungs

No one knows for sure how they got there. But the discovery that bacteria that normally live in the gut can be detected in the lungs of critically ill people and animals could mean a lot for intensive care patients. [More]
Researchers discover how Zika virus travels from pregnant mother to fetus

Researchers discover how Zika virus travels from pregnant mother to fetus

Zika virus can infect numerous cell types in the human placenta and amniotic sac, according to researchers at UC San Francisco and UC Berkeley who show in a new paper how the virus travels from a pregnant woman to her fetus. They also identify a drug that may be able to block it. [More]
AMSBIO launches new CRISPR gRNA Lentivector Cloning Kits

AMSBIO launches new CRISPR gRNA Lentivector Cloning Kits

Anglo-American life science firm AMSBIO has introduced new CRISPR gRNA Lentivector Cloning Kits that provide scientists with a targeted and precise genomic gene editing methodology. [More]
Growing concerns about drug resistance highlight importance of preventing gonorrhea infection

Growing concerns about drug resistance highlight importance of preventing gonorrhea infection

A recent analysis by the Centers for Disease Control and Prevention (CDC) indicates that the bacteria responsible for gonorrhoea may be developing resistance to one of the current treatments for the infection — the antibiotic azithromycin. [More]
Rare antibiotic compound detected in fungi for first time

Rare antibiotic compound detected in fungi for first time

Besides mushrooms such as truffles or morels, also many yeast and mould fungi, as well as other filamentous fungi belong to the Ascomycota phylum. They produce metabolic products which can act as natural antibiotics to combat bacteria and other pathogens. Penicillin, one of the oldest antibiotic agents, is probably the best known example.

Experts call on UN to implement four-part global action plan to increase access to effective antibiotics

Experts call on UN to implement four-part global action plan to increase access to effective antibiotics

Today some of the world's foremost experts on antibiotic resistance called on the United Nations General Assembly to decisively act to reduce the growing number of deaths due to limited access to effective antibiotics. [More]
IDSA/ATS recommends shorter courses of antibiotics for patients with hospital-acquired, ventilator-associated pneumonia

IDSA/ATS recommends shorter courses of antibiotics for patients with hospital-acquired, ventilator-associated pneumonia

Hospital-acquired pneumonia and ventilator-associated pneumonia– which account for 20 to 25 percent of hospital-acquired infections – should be treated with shorter courses of antibiotics than they typically are, according to new guidelines released by the Infectious Diseases Society of America and American Thoracic Society and published in the journal Clinical Infectious Diseases.

Fecal transplants may help treat home and hospital-acquired scourge

Fecal transplants may help treat home and hospital-acquired scourge

Fecal transplants are increasingly being used as the treatment of last resort for certain infections in the human gut and have had remarkable success treating the nursing home and hospital-acquired scourge, Clostridium difficile colitis, an infectious diarrhea that often follows antibiotic treatment.

Italian researchers identify new variant of emerging antibiotic resistance mechanism

Italian researchers identify new variant of emerging antibiotic resistance mechanism

A team of Italian investigators has discovered a new variant of an emerging antibiotic resistance mechanism. The new variant, dubbed mcr-1.2, confers resistance to colistin, a last-resort antibiotic against multidrug-resistant Gram-negative pathogens. [More]
