In recent research, scientists from Brigham Young University, UK, found a new way to complete the whole blood sampling and analysis process for the identification of antibiotic-resistant bacteria in the blood that takes just 1 hour (instead of 24 hours of the traditional method).
This method includes a process of blood spinning, through which the bacteria are isolated from the samples so their DNA and can be analyzed. The scientists used fluorescent molecules able to bind specifically to segments of bacterial DNA that contain known antibiotic-resistant genes. If these genes are in the sample, they can be detected by a microchip.
Researcher Aaron Hawkins, an electrical and computer engineer at Brigham Young University, comments on the results of the study: “Once you’re trying to diagnose the disease, the clock is ticking. Every hour the disease is untreated, survivability drops by about 7 percent. You want to know what you’re fighting immediately so you can apply the right treatments.”
According to a new study from the University of Colorado at Boulder, USA, strange quantum particles controlled with specific wavelengths of light can destroy superbug infections like E. coli and Salmonella into dropping their guard.
The researchers re-designed existing antibiotics for specific clinical isolate infections via nano-engineered quantum particles which they introduced by special selection. They activated or de-activated the particles using key wavelengths of light.
Co-lead author of the study Prashant Nagpal, an assistant professor at CU Boulder’s Department of Chemical and Biological Engineering (CHBE), says: “We’ve developed a one-two knockout punch. The bacteria’s natural fight reaction [to the dots] actually leaves it more vulnerable.”
A team of researchers from McGill University discovered that maple syrup extract can decrease the usage of antibiotic by improving the potentiality of the medicine.
At the first stage of the study, lead researcher Natalie Tufenkji separated the sugar and water from the syrup’s phenolic compounds and exposed with several bacterial strains that cause various disease. However, she didn’t find any noticeable changes. But when she mixed the phenolic extract with commonly used antibiotics then the antimicrobial potency hiked up.
Dr. Tufenkji explained that the syrup extract actually increases the permeability of bacteria that helps antibiotics to gain access to the interior of cells.
A new study, executed by the team of scientists from Emory University, finds that red berries of the Brazilian peppertree contain a substance able to fight deadly superbugs.
For the study, the scientists separated the ingredients of the berries to see if they could prevent methicillin-resistant Staphylococcus aureus (MRSA) infections in mice. The MRSA is a drug-resistant superbug posing a risk to hospital patients. The researchers injected all rodents with the bacteria and gave the plant compound to some of them. Those rodents that received plant compound inhibited the growth of lesions.
Lead researcher Cassandra Quave, an assistant professor in Emory’s Center for the Study of Human Health and in the School of Medicine’s Department of Dermatology, says: “We’re really at an urgent time for discovery of new chemical matter and new mechanisms for dealing with infectious diseases because we are standing on the precipice of a post-antibiotic era.”
