Mutations Acquired Trans-Pacific May Be Key to Changes in Zika Severity
December 13th 2016The Zika virus remains a mystery. Isolated from macaque monkeys in the Ziika Forest in Uganda in 1947, the virus was shown to infect humans not long after, but it was identified as a benign disease, with mild symptoms. For this reason, it was not heavily studied until almost 70 years later when it appeared to be associated with an unusual cluster of cases of microcephalic birth defects and Guillain-Barré Syndrome (GBS) paralysis in Brazil in 2015 and 2016.
Scientist Identifies Natural Weapons Against Antibiotic Resistance
December 13th 2016Dr. Hans Wildschutte has his eye on finding answers to the serious global issues of antibiotic resistance and novel drug discovery. The research in Wildschutte’s lab focuses on finding environmental bacteria that can kill one or multiple pathogens.
Worm Treatment Strategy Could Benefit Millions of Kids
December 13th 2016A landmark new study shows the benefits of an expanded treatment strategy for intestinal worms -- treating adults as well as children -- that could improve the health of millions of children in Southeast Asia, the Pacific and Africa. Dr. Naomi Clarke from the Australian National University (ANU) said children from the poorest communities suffered from consequences of infestations, such as poor growth and development, and chronic intestinal blood loss and anemia in some cases.
Nasal Decolonization and HAI Prevention: Applications and Evidence
December 13th 2016Healthcare-associated infections (HAIs) affect more than 2 million patients annually and cost over $4.5 billion. Infection prevention bundles are increasingly being used that include nasal decolonization, and evidence supporting its effectiveness is growing. Although mupirocin (trade names including Bactroban, Centany) is commonly used for nasal decolonization, it may be prudent to consider new nasal antiseptics with which antimicrobial resistance is not an issue [trade names including Nozin (alcohol) and 3M and Clorox (iodine).
AORN Talks Guideline Development for Perioperative Nurses
December 12th 2016Every year, the Association of periOperative Registered Nurses (AORN) releases the latest version of its Guidelines for Perioperative Practice to its 41,000 members. Each edition of the book features updated instruction on practices that help perioperative nurses and, in turn, infection preventionists, ensure patient health and safety. For example, the 2017 publication contains detailed new insight into hand hygiene in the surgi-cal suite. The information discusses how fingernails, and even polish, can harbor germs, and offers best practices for preventing contamination that could hurt the patient. Through the teaching efforts of AORN members, and the acceptance of the U.S. Agency for Healthcare Research and Quality National Guideline Clearinghouse, these directions will reach more than 2,500 hospitals and more than 160,000 RNs.
NIH Scientists Develop New Mouse Model to Study Salmonella Meningitis
December 12th 2016National Institutes of Health (NIH) scientists have established in mice a way to study potentially life-threatening meningitis caused by Salmonella. Bacterial meningitis happens when bacteria infect the central nervous system (CNS), causing a serious disease that can be life-threatening and difficult to diagnose and treat. Patients who survive often have permanent brain damag
New Evidence Shows How Bacterium in Undercooked Chicken Causes GBS
December 9th 2016A Michigan State University research team is the first to show how a common bacterium found in improperly cooked chicken causes Guillain-Barre Syndrome (GBS). The federally funded research, now published in the Journal of Autoimmunity, not only demonstrates how this food-borne bacterium, known as Campylobacter jejuni, triggers GBS, but offers new information for a cure. If chicken isn't cooked to the proper minimum internal temperature, bacteria can still exist.
Smallpox May Have Emerged in More Recent Times, Raising Questions About Its Role in History
December 8th 2016New genetic research from an international team including McMaster University, University of Helsinki, Vilnius University and the University of Sydney, suggests that smallpox, a pathogen that caused millions of deaths worldwide, may not be an ancient disease but a much more modern killer that went on to become the first human disease eradicated by vaccination.
Scientist Studies the Infant Resistome to Combat Superbugs
December 8th 2016Gautam Dantas remembers the day in 10th grade when he first wanted to be a scientist. It was the day he had a new biology teacher, a visiting researcher from the U.S. The teacher passionately described his own biochemical studies of how organisms live together in communities. By the end of the class, Dantas had resolved to earn a PhD in biochemistry. He ended up doing much more-gaining expertise in computational biology, protein design and synthetic biology. He now combines his skills and knowledge in multifaceted research that spans four departments at the Washington University in St. Louis. His goal: to better understand and help combat a vital public health threat-drug-resistant bacteria.
Oxygen Can Wake Up Dormant Bacteria for Antibiotic Attacks
December 8th 2016Bacterial resistance does not come just through adaptation to antibiotics, sometimes the bacteria simply go to sleep. An international team of researchers is looking at compounds that attack bacteria's ability to go dormant and have found the first oxygen-sensitive toxin antitoxin system.
Protein Disrupts Infectious Biofilms
December 8th 2016Many infectious pathogens are difficult to treat because they develop into biofilms, layers of metabolically active but slowly growing bacteria embedded in a protective layer of slime, which are inherently more resistant to antibiotics. Now, a group of researchers at Caltech and the University of Oxford have made progress in the fight against biofilms. Led by Dianne Newman, the Gordon M. Binder/Amgen Professor of Biology and Geobiology, the group identified a protein that degrades and inhibits biofilms of Pseudomonas aeruginosa, the primary pathogen in cystic fibrosis (CF) infections.
