Researchers at McMaster University have developed a sophisticated new tool that could help provide early warning of rare and unknown viruses in the environment and identify potentially deadly bacterial pathogens which cause sepsis, among other uses.
A multinational effort is underway to understand and control the spread of disease among migratory birds.
In previously unstudied gopher tortoise aggregations, researchers found that overall, 42.9 percent had circulating antibodies to an infectious bacterium that causes upper respiratory tract disease. Physical examination showed that 19.8 percent had clinical signs consistent with upper respiratory tract disease and 13.2 percent had some form of physical abnormality. None of the tortoises tested positive for Ranavirus or Herpesvirus, which represents important baseline data, since these viruses are thought to be emerging pathogens of other tortoise and turtle species.
The Institute for the Advancement of Food and Nutrition Sciences (IAFNS) today is opening a free online portal for the public to submit ideas on science projects related to nutrition and food safety.
Removing pathogens from drinking water is especially difficult when the germs are too tiny to be caught by conventional filters. Researchers at Empa and Eawag are developing new materials and processes to free water from pathogenic microorganisms such as viruses.
In a time when most people are avoiding diseases like the plague, one WVU biology student is pursuing them instead.
As the pandemic continues, scientists are increasingly focused on developing methods to assist in decontaminating surfaces and spaces. In Review of Scientific Instruments, researchers report on experimental tools capable of presenting electromagnetic waves to an aerosol mixture with the capability to vary power, energy, and frequency of the electromagnetic exposure. The researchers seek to better characterize the threshold levels of microwave energy needed to inactivate aerosolized viral particles and reduce their ability to spread infection.
Many people reuse masks and other face coverings many times without sanitizing them. That is likely because current sanitization methods can be cumbersome. A new device using a hanging rack and UV-C light can sterilize up to six masks and other items simultaneously and quickly, killing bacteria, yeasts, mold spores, and viruses. This device has shown its efficacy against pathogens including the highly-contagious E-coli, which was eradicated in about one minute.

Plants have sophisticated defense mechanisms that activate specific genes in response to specific pathogens. Scientists investigated the tradeoffs in plant defenses against two pathogens. They identified a protein in Arabidopsis plants that regulates genes involved in pathogen response to target defenses.
A study aimed at better understanding why some critically ill patients develop multidrug-resistant infections is underway by researchers at The University of Texas Health Science Center at Houston (UTHealth). The multi-institution study will enroll patients at Memorial Hermann Hospital-Texas Medical Center and The University of Texas MD Anderson Cancer Center.
A tick species associated with bats has been reported for the first time in New Jersey and could pose health risks to people, pets and livestock, according to a Rutgers-led study in the Journal of Medical Entomology. This species (Carios kelleyi) is a “soft” tick. Deer ticks, which carry Lyme disease, are an example of “hard” ticks.
In a study of New York state apple orchards, Cornell University plant pathologists have identified a new fungal pathogen that causes bitter rot disease in apples.
Can antibiotic-resistant bacteria escape from sewers into waterways and cause a disease outbreak? A new Rutgers study, published in the journal Environmental Science: Water Research & Technology, examined the microbe-laden “biofilms” that cling to sewer walls, and even built a simulated sewer to study the germs that survive within.
There’s some good news in New Jersey about a potentially deadly tick-borne bacterium. Rutgers researchers examined more than 3,000 ticks in the Garden State and found only one carrying Rickettsia rickettsii, the bacterium that causes Rocky Mountain spotted fever. But cases of tick-borne spotted fevers have increased east of the Mississippi River, and more research is needed to understand why, according to a study in the American Journal of Tropical Medicine and Hygiene.
Like a scene out of “Invasion of the Body Snatchers,” a virus infects a host and converts it into a factory for making more copies of itself.
Using a newly developed approach, researchers have identified seasonal peaks for foodborne infections that could be used to optimize the timing and location of food inspections.
New Brunswick, N.J. (May 21, 2020) – Rutgers University–New Brunswick Professor Kay Bidle is available for interviews on the possible risks from the novel coronavirus or other pathogens while swimming or surfing in oceans, bays, lakes and rivers. “We currently know very…
A new Cornell University study on bees, plants and landscapes in upstate New York sheds light on how bee pathogens spread, offering possible clues for what farmers could do to improve bee health.
The Pathogen and Microbiome Institute (PMI) at Northern Arizona University (NAU) today announced that it is launching the COVID-19 Testing Service Center (CTSC) to grow the SARS-CoV-2 virus and test new drugs against it. By repurposing its existing biodefense research infrastructure for the new testing facility—labs rated at Biosafety Level 3 (BSL-3), one of the highest levels of biocontainment—PMI is dedicating much of its significant research capacity to fight the COVID-19 pandemic.
As social distancing is now being practiced at all levels of human society in order to mitigate a pandemic’s spread, a Virginia Tech expert in disease ecology says we need to look no further than our animal counterparts to understand why…
Researchers in China have discovered how a Zika virus protein reshapes its host cell to aid viral replication. The study, which will be published December 23 in the Journal of Cell Biology, reveals that the viral protein NS1 converts an interior cellular compartment called the endoplasmic reticulum (ER) into a protective region where the virus can survive and replicate. Blocking this process could be a novel therapeutic strategy to treat patients infected with Zika or similar viral pathogens, such as the yellow fever and dengue viruses.
