New Portable Device Lets Smartphones Count Real Biological Viruses
July 30th 2019The current leading method to assess the presence of viruses and other biological markers of disease is effective but large and expensive. It is prohibitively difficult for use in many situations, especially due to certain economic and geographic factors.
For Salmonella Detection, Genomic Tool Emerges as a Key
July 29th 2019The world's food supply will become safer as the food industry shifts to high-resolution, whole-genome sequencing - which examines the full DNA of a given organism all at once. This move to make sequencing ubiquitous will lead to the consistently reliable detection of salmonella.
When Flesh-Eating Bacteria Move into New Waters: How to Stay Safe
July 29th 2019Infections caused by the bacterium Vibrio vulnificus – known as “flesh eating” bacteria – are becoming more common in northern waters, whose surface temperatures are rising due to climate change. A recent study showed that infections are increasing in areas further north such as the Delaware Bay.
Viral HIV Vaccine Gives Durable Protection Against 'Death Star' Strain
July 25th 2019Among HIV researchers, one seemingly indestructible HIV-like strain has earned the nickname "death star." That's due to the strain's reputation for killing off hopes for potential vaccines and immunotherapies that could prevent the disease.
Bacteria-Killing Gel Heals Itself While Healing You
July 25th 2019McMaster University researchers have developed a novel new gel made entirely from bacteria-killing viruses. The anti-bacterial gel, which can be targeted to attack specific forms of bacteria, holds promise for numerous beneficial applications in medicine and environmental protection.
Mouse, Not Just Tick: New Genome Heralds Change in Lyme Disease Fight
July 25th 2019As Lyme disease increases, researchers have taken a significant step toward finding new ways to prevent its transmission. The experts, who include a pioneer in Lyme disease discovery, have sequenced the genome of the animal carrying the bacteria that causes the illness.
Scientists Pinpoint New Mechanism That Impacts HIV Infection
July 24th 2019A team of scientists led by Texas Biomed's Assistant Professor Smita Kulkarni, PhD and Mary Carrington, PhD, at the Frederick National Laboratory for Cancer Research, published results of a study that pinpointed a long noncoding RNA molecule which influences a key receptor involved in HIV infection and progression of the disease.
Connection to HIV Care Helps Underserved U.S. Populations Suppress the Virus
July 23rd 2019Gay, bisexual and other men who have sex with men and transgender women with HIV, who are not in care, can be engaged in care when reached and connected with HIV treatment services, according to findings from a clinical trial supported by the National Institutes of Health.
Genes Linked to Sepsis-Related Death are Identified in Mouse Model
July 23rd 2019Sepsis is a life-threatening condition that occurs when the body’s immune response to infection spirals out of control. Bacteria in the bloodstream trigger immune cells to release powerful molecules called cytokines to quickly activate the body’s defenses.
Johns Hopkins Co-Leads Research Effort on Child ‘Poliolike’ Condition
July 23rd 2019Johns Hopkins Medicine and University of Alabama at Birmingham (UAB) researchers will lead a multicenter, multinational study of acute flaccid myelitis (AFM), the “poliolike” condition affecting children that causes loss of muscle control.
Researchers Develop Novel Vaccine That Induces Antibodies That Contribute to Protection
July 23rd 2019Researchers at the Icahn School of Medicine at Mount Sinai have developed a novel vaccine consisting of DNA and recombinant proteins composed of a portion of an HIV protein and another unrelated protein. This vaccine was tested in monkeys and was shown to induce antibodies similar to those associated with protection from HIV, the virus that causes AIDS.
Rise of Candida auris Blamed on Global Warming
July 23rd 2019Global warming may have played a pivotal role in the emergence of Candida auris, according to a new study published in mBio, an open-access journal of the American Society for Microbiology. C. auris, which is often multi-drug resistant and is a serious public health threat, may be the first example of a new fungal disease emerging from climate change.
Declaration of PHEIC in DRC Should Spur Support, Not Fear
July 22nd 2019The World Health Organization’s declaration that the year-long Ebola crisis is a Public Health Emergency of International Concern (PHEIC) is hoped to raise much-needed awareness and resources for preparedness and control efforts across the region, says the Infectious Diseases Society of America (IDSA).
Researcher Discovers How Mosquitoes Integrate Vision and Smell to Track Victims
July 22nd 2019Scientists have found that mosquitoes are changing their hunting routines in response to host cues. For example, in Africa, mosquitoes now recognize when people emerge from bednets in the morning and have begun hunting more often during the day than at night.
Understanding Determinants of Infection Control Practices in Surgery
July 22nd 2019Despite a large literature on surgical site infection (SSI), the determinants of prevention behaviors in surgery remain poorly studied. Understanding key social and contextual components of surgical staff behaviour may help to design and implement infection control (IC) improvement interventions in surgery.
Evaluation of the Complexity of Indoor Air in Hospital Wards
July 22nd 2019The aim of this study by Ling and Hui (2019) was to establish a set of assessment methods suitable for evaluating the complex indoor environment of hospital wards and to ascertain the composition of bacteria and microbial ecology of hospital wards.
Phytochemicals are a Valuable Source of Bioactive Compounds With Potent Antimicrobial Activities
July 22nd 2019Microbial resistance to classical antibiotics and its rapid progression have raised serious concern in the treatment of infectious diseases. Recently, many studies have been directed toward finding promising solutions to overcome these problems. Phytochemicals have exerted potential antibacterial activities against sensitive and resistant pathogens via different mechanisms of action.
FDA Approves New Treatment for Complicated Urinary Tract and Intra-abdominal Infections
July 18th 2019The Food and Drug Administration (FDA) has approved Recarbrio (imipenem, cilastatin and relebactam), an antibacterial drug product to treat adults with complicated urinary tract infections (cUTI) and complicated intra-abdominal infections (cIAI).
Factors That Make People More Receptive to Vaccination Against Infectious Disease
July 18th 2019Fear, trust and the likelihood of exposure are three leading factors that influence whether people are willing to be vaccinated against a virulent disease, according to a new study in the journal Heliyon, published by Elsevier.
Link Found Between Gut Bacteria, Successful Joint Replacement
July 18th 2019Having healthy gut flora -- the trillions of bacteria housed in our intestines -- could lower the risk of infection following knee and hip replacement surgeries, while an unhealthy intestinal flora may increase the risk of infection.
