In fact, its creation was rather strange. To model OIAI in rabbits, a medial parapatellar arthrotomy was performed to ream the femoral canal, and a bright bioluminescent methicillin-resistant Staphylococcus aureus (MRSA) strain was inoculated into the canal, followed by retrograde insertion of the coated implant flush with the articular surface. In vivo BLI signals were confirmed by ex vivo colony-forming units (CFUs) from tissue, bone, and implant specimens.Results:In this rabbit model of OIAI (n = 6 rabbits per group), implants coated without antibiotics were associated with significantly increased knee width and in vivo BLI signals compared with implants coated with linezolid-rifampin (p < 0.001 and p < 0.05, respectively). This can put projects and people at risk by revealing the presence of submarines, or even Navy SEALs swimming around covertly. type of bioluminescence used by organisms to hide from predators below by blending in with the light patterns above. So they would eventually die. Bioluminescent biotechnology is one seemingly innocent branch of science that has brought some interesting ideas to the table. Washington, DC 20036, National Geographic Society is a 501 (c)(3) organization. Yet the question remains: How will a glowing fish benefit society? On day 7, the implants without antibiotics were associated with significantly increased CFUs from tissue (mean [and standard error of the mean], 1.4 × 108 ± 2.1 × 107 CFUs; p < 0.001), bone (6.9 × 106 ± 3.1 × 106 CFUs; p < 0.05), and implant (5.1 × 105 ± 2.2 × 105 CFUs; p < 0.05) specimens compared with implants with linezolid-rifampin, which demonstrated no detectable CFUs from any source.Conclusions:By combining a bright bioluminescent MRSA strain with modified techniques, in vivo BLI in a rabbit model of OIAI demonstrated the efficacy of an antibiotic-releasing coating.Clinical Relevance:The new capability of in vivo BLI for noninvasive monitoring of bacterial burden in larger-animal models of OIAI may have important preclinical relevance.

T1 - In Vivo Bioluminescence Imaging in a Rabbit Model of Orthopaedic Implant-Associated Infection to Monitor Efficacy of an Antibiotic-Releasing Coating. Post was not sent - check your email addresses! The predator will follow the glow on the fish, while the sea cucumber crawls away. Would I ever add a GloFish to my aquarium? to emit a continuous stream of light over a long period of time. Hatchetfish have light-producing organs that point downward. The fish were supposed to indicate, by glowing, if a given body of water is polluted.”. Organisms can luminesce when they are disturbed. The goal of this study was to develop a larger, rabbit model of OIAI using in vivo BLI to evaluate the efficacy of an antibiotic-releasing implant coating.Methods:A nanofiber coating loaded with or without linezolid-rifampin was electrospun onto a surgical-grade locking peg. Biologists think that some species of sharks and whales may take advantage of defensive bioluminescence, even though they are not bioluminescent themselves. BIOTECHNOLGY is a fascinating field. tactic that organisms use to disguise their appearance, usually to blend in with their surroundings. Change ), You are commenting using your Facebook account. (plural: fungi) type of organism that survives by decomposing and absorbing the material in which it grows. Bioluminescence is of great interest to the Navy. light emitted by some fungi as they decay wood. However, technical limitations have limited its use to mouse and rat models of OIAI. light emitted by a source that produces very little thermal radiation. organic substances that upon oxidation produce a virtually heatless light (bioluminescence). However, the idea of a rogue GloFish escaping its aquarium and spawning an army of mutant glow-fish in the wild that ultimately wipe out other species of fish does not presently have a lot of backing. It has so much to offer society, and it is not inaccurate to say that it will inevitably be the salvation of our planet. process that involves a change in atoms, ions, or molecules of the substances (reagents) involved. - GeenCommentaar, @Ben: Feed one a lot of fluorescence and that might just happen . Bioluminescence may be generated by symbiotic organisms carried within a larger organism. Sorry, your blog cannot share posts by email. Terms of Service | AB - Background:In vivo bioluminescence imaging (BLI) provides noninvasive monitoring of bacterial burden in animal models of orthopaedic implant-associated infection (OIAI). and Thompson, {John M.} and Jesse Zheng and Marchitto, {Mark C.} and Archer, {Nathan K.} and Pinsker, {Bret L.} and Ortines, {Roger V.} and Xuesong Jiang and Martin, {Russell A.} ( Log Out / It's been 10 years since scientists finished mapping the human genome---so what have we accomplished since? associating with another organism, not always to the mutual benefit of either species. Biologists and engineers are studying the chemicals and, Green fluorescent protein (GFP), for instance, is a valuable "reporter gene. Satellite imagery of milky seas have been captured in tropical waters such as the Indian Ocean. • Christmas trees that do not need lights, reducing danger from electrical fires. author = "Miller, {Robert J.} If you're a male, be grateful that you have/had a father who taught you…. The pet industry is in many ways a peculiar venue for such a heated debate over the wisdom of genetic modification. enzyme (catalyst) that reacts with a substrate (luciferin) in a chemical reaction that results in bioluminescence.

Naturally black and white, the new GloFish has gone from curiosity to a focal point in the debate over biotechnology.
