  • New experimental test detects signs of Lyme disease near time of infection
    Clinical Realities and the Human Dimensions of Interoperable Data The current standard blood test for Lyme disease exposes the infection only after antibodies have accumulated to detectable levels which can take up to 4 to 6 weeks If patients exhibit a telltale bull s eye rash diagnosis and treatment can begin earlier But the rash does not occur in 20 to 30 percent of Lyme disease patients according to the Centers for Disease Control and Prevention Rather than waiting for an infected person s immune system to produce noticeable amounts of antibodies the team chose to home in on the bacteria itself specifically proteins the bug sheds when attacked by the body s defenses From many candidates we chose one that is both easily distinguished from human serum proteins and an unambiguous indicator of the bacteria Turko says This protein which resides on the outer surface of membranes became the target of our search in serum samples But finding that target required an important preliminary step to ensure the accuracy of their measurements making a reference sample that contained ample amounts of the target protein With the reference sample the team established the unmistakable signature the bug s outer surface membrane protein would yield when they examined samples drawn from patients As a result of these steps the team could detect the copies of the target protein even though human proteins were 10 million times more plentiful We believe that this approach may be universally applicable to detection of other bacterial infections in humans the researchers write Explore further Combined team of physicists and biologists build Lyme disease detector using carbon nanotube sensor More information C S F Cheung K W Anderson K Y Villatoro Benitez M J Soloski J N Aucott K W Phinney and I V Turko Quantification of Borrelia burgdorferi Membrane Proteins in Human Serum A New Concept for Detection of Bacterial Infection Analytical Chemistry 2015 87 11383 11388 Journal reference Analytical Chemistry Provided by National Institute of Standards and Technology 9 shares feedback to editors Tweet Favorites Email Print PDF Featured Last comments Popular Detection of gravitational waves would open new window on universe Feb 10 2016 58 Gravitational waves detected 100 years after Einstein s prediction Feb 11 2016 144 Scientists discover hidden galaxies behind the Milky Way Feb 09 2016 3 GPS tracking down to the centimeter Feb 11 2016 10 A metal that behaves like water Feb 11 2016 2 more Phys org on facebook Relevant PhysicsForums posts When is ΔH ΔU 5 hours ago Which group has greater steric hindrance Feb 11 2016 Comparison Calibration Method Feb 11 2016 Which compound will be extracted in organic layer Feb 10 2016 Kinetic vs thermodynamics control Feb 10 2016 Electroplating with mixed metal electrodes Feb 10 2016 More from Chemistry Related Stories Combined team of physicists and biologists build Lyme disease detector using carbon nanotube sensor June 17 2013 Phys org A team made up of researchers from both the physics and biology departments
