“A problem so serious that it threatens the achievements of modern medicine,
The growth of antibiotic-resistant pathogens means that in ever more cases, standard treatments no longer work, infections are harder or impossible to control, the risk of spreading infections to others is increased, and illnesses and hospital stays are prolonged.
All of these drive up the costs of illnesses and the risk of death. The survey sought to determine the scope of the problem by asking countries to submit their most recent surveillance data (114 did so). Unfortunately, the data was glaringly incomplete because few countries track and monitor antibiotic resistance comprehensively, and there is no standard methodology for doing so.
Still, it is clear that major resistance problems have already developed, both for antibiotics that are used routinely and for those deemed “last resort” treatments to cure people when all else has failed.
Carbapenem antibiotics, a class of drugs used as a last resort to treat life-threatening infections caused by a common intestinal bacterium, have failed to work in more than half the people treated in some countries. The bacterium is a major cause of hospital-acquired infections such as pneumonia, bloodstream infections, and infections in newborns and intensive-care patients. And resistance to a class of antibiotics that is routinely used to treat urinary tract infections caused by E. coli is widespread; in some countries the drugs are now ineffective in more than half of the patients treated. This sobering report is intended to kick-start a global campaign to develop tools and standards to track drug resistance, measure its health and economic impact, and design solutions.
~ importance of the archean Thermus aquaticus.
They are used in Polymerase Chain Reaction (PCR) wherein it aids in the further amplification, meaning, making several copies, of a DNA of a certain organism that you want to amplify. These amplified DNA strands are used in many different genetic research in order to accurately obtain the full gene sequences of a certain organism.
This particular enzyme is what you call as the Taq polymerase which is the primary enzyme responsible for the amplification step of PCR. This particular enzyme is needed in PCR in amplifying several full strands of DNA because in this process, particularly in the elongation part of replication, heat is required. Therefore, this kind of polymerase from a thermophilic archaean bacteria, Thermus aquaticus, will be very helpful since if a regular polymerase from a non-thermophilic bacteria is used, it cannot tolerate the high temperature and will just denature and become useless.
