The new sensor provides a quick test to measure antibiotic resistance-ScienceDaily
UBC researchers have developed a way to monitor the bacterial response to antibiotics in the medical setting, opening the door to individualized antibiotic therapies for patients.
Using microwave sensing technology, UBC Okanagan Assistant Professor Mohammad Zarifi of the Okanagan Microelectronics and Gigahertz Applications (OMEGA) Lab and his team act as a fast and reliable evaluation tool for measurements at low cost. Developed a non-contact, portable, reusable microwave sensor Antibiotic resistant.
According to the World Health Organization, over-prescribing antibiotics increases the resistance of bacteria to drug treatment. As a result, the newly evolved “super bugs” are putting a heavy burden on healthcare systems around the world, Zarifi said.
This newly developed sensor addresses the shortcomings of current antibiotic susceptibility testing (AST) to reduce the time and cost of conducting tests while increasing the portability of ASTs used in remote areas. Is aimed at.
“Many types of bacteria are constantly evolving to develop resistance to antibiotics. This is an urgent issue for hospitals around the world, but the adaptation of sensors and diagnostic techniques has been delayed,” said the Faculty of Engineering. The teaching Zarifi explains.
Existing AST practices are expensive and can take up to 48 hours to process the results.
“Long wait times can significantly delay the treatment patients receive, leading to further complications and death. This method demonstrates the need for reliable, fast and cost-effective detection tools. “He says.
A new sensor developed by the UBC team can distinguish between bacterial growth fluctuations before visible clues are revealed. Therefore, the dose or type of antibiotic can be fine-tuned to combat a particular bacterial infection.
In the next phase of development, OMEGA Labs aims to integrate artificial intelligence algorithms with this sensing device to develop smart sensors that will be a major leap forward for personalized antibiotic therapy.
“Our ultimate goal is to reduce inappropriate use of antibiotics and improve the quality of care for our patients,” says Zarifi. “The more such high-quality tools that healthcare professionals have at their disposal, the better they are at fighting bacteria and viruses.”
