According to a UN-agreement, assistance dogs like guide dogs, signal dogs and medical response dogs are welcome in hospitals and other public places. However, in practice, they are regularly refused entry. Hygiene reasons are often given as the main argument for this. Research by Utrecht University now shows that the paws of assistance dogs are cleaner than the shoe soles of their users, and thus, paw hygiene is no reason to ban assistance dogs from hospitals.
A combined treatment of irradiation and essential oil vapors could effectively destroy insects, bacteria and mold in stored grains. The team of INRS Professor Monique Lacroix has demonstrated the effect of this process on insects affecting rice. The study was published in the Radiation Physics and Chemistry journal.
The illegal wildlife trade is often seen as one of the major gateways to zoonotic diseases, that spread from animals to humans. While the illegal trade in tigers, ivory, rhino horn, pangolins and primates is of paramount concern for public health, Professor Nijman says the legal wildlife trade should be of equal concern.
Using theoretical models of bacterial metabolism and reproduction, scientists can predict the type of resistance that bacteria will develop when they are exposed to antibiotics. This has now been shown by an Uppsala University research team, in collaboration with colleagues in Cologne, Germany. The study is published in the journal Nature Ecology and Evolution.
Targeted, efficient and with few side effects: A new method for combating periodontitis could render the use of broad-spectrum antibiotics superfluous. It was developed and tested for the first time by a team from Martin Luther University Halle-Wittenberg (MLU), the Fraunhofer Institute for Cell Therapy and Immunology IZI and Periotrap Pharmaceuticals GmbH. The aim is to neutralise only bacteria that cause periodontitis while sparing harmless bacteria. The study appeared in the Journal of Biological Chemistry.
A new study has shown that gentle streams of water carrying sound and microscopic air bubbles can clean bacteria from salad leaves more effectively than current washing methods used by suppliers and consumers. As well as reducing food poisoning, the findings could reduce food waste and have implications for the growing threat of anti-microbial resistance.
New research suggests that the ability of green algae to eat bacteria is likely much more widespread than previously thought, a finding that could be crucial to environmental and climate science. The work, led by scientists at the American Museum of Natural History, Columbia University, and the University of Arizona, found that five strains of single-celled green algae consume bacteria when they are "hungry," and only when those bacteria are alive.
Envisioning an animal-free drug supply, scientists have -- for the first time -- reprogrammed a common bacterium to make a designer polysaccharide molecule used in pharmaceuticals and nutraceuticals.
University of Montana researchers and their partners have discovered a slimy strategy used by bacteria to defeat antibiotics and other drugs used to combat infections afflicting people with cystic fibrosis. The research was published Feb. 23, 2021 in the journal Cell Reports.
The pandemic has made clear the threat that some viruses pose to people. But viruses can also infect life-sustaining bacteria and a Johns Hopkins University-led team has developed a test to determine if bacteria are sick, similar to the one used to test humans for COVID-19.
