Dr Rowley Richards talks about how antibiotics were considered a 'miracle drug' when they were first developed because of their ability to save lives — and of the avoidable deaths that occurred without access to antibiotics during World War II. Dr Richards was a doctor and POW in the Australian army. He talks about the miracle that was antibiotics offered and the difficulties in treating his fellow soldiers without them.

(Visit: http://www.uctv.tv/) Antibiotics are considered a miracle of modern medicine — our "magic bullets" that kill harmful microorganisms and spare our bodies in the war against infection. Conan MacDougall explains that the story is much more complex. Most of the bugs that would do us harm usually co-exist with us on our skin, in our gut — and in our cells themselves. The indiscriminate killing of bacteria by antibiotics and disinfectants may deprive us of nutrients and deny our immune system the "training" it needs to distinguish self from non-self — leading to an increase in autoimmune diseases. And the rise of antibiotic resistance requires us to examine how we deal with uncertainty and risk and our responsibilities to current and future patients.

Discovered 100 years ago, bacteriophages—viruses that eat bacteria—might provide an answer. But phage therapy has only been approved for use on humans in the former Soviet Union.

In the late 1930s, sulfa drugs became the first widely-used antibacterial drugs. They weren't effective against all bacteria, but they saved many lives during the Second World War. Theo's ancestor was a radio announcer with the Bacterial Broadcasting Centre (BBC) and this newly-rediscovered archive film documents how news of the new drugs reached the bacterial community. OF COURSE this is fictional -- but see if you can find out more about sulfa drugs and their use in the Second World War.

Antibiotics have been credited to saving countless lives. Penicillin, discovered in 1928 by Sir Alexander Fleming, is recognized as one of the greatest advances in therapeutic medicine. The life-saving drug was first mass produced in the U.S. during World War II, and helped launch the golden era of antibiotics. Today, medical researchers have a concern about these medications: overuse and misuse of antibiotics, leading to antibiotic resistance. Mayo Clinic pediatric infectious disease specialist Dr. Nipunie Rajapakse says antibiotic resistance is a serious public health threat.

What are antibiotics, how do they work and why do we see resistance in antibiotic.. this video answers all these questions. Alexander Fleming discovered in 1928 when he found Pencillium and Penicillin was found. There are two types of Antibiotic Bactereostatic and Bactericidal Bother antibiotics have different mode of action and play major role in immunity. Antibiotics are only available against Bacteria but not virus. Antibiotics stop DNA replication or stop its metabolism or it also stops its enzyme or substrate. Penicillin kills the bacteria by rupturing its bacterial cell wall, thereby killing bacteria but not harming our body cells. usage of antibiotics also effect normal flora of our body which becomes a challenge are a lot of our functions are dependent upon them. Antibiotics kill our helpful bacteria as well thereby disturbing our normal functions of body and causing side effects. Evolution of bacteria and their mutation caused a war between scientist and bacteria as they started mutating against antibiotics and we had to made newer and newer generation of antibiotics while bacteria kept challenging us.

(Visit: http://www.uctv.tv/) Patients are frequently given the wrong antibiotics to treat bacterial infections, but it is not the physician who is at fault. The standard antibiotic test used worldwide is flawed since it is based on how well drugs kill bacteria on petri plates — not how well they kill bacteria in the body. Mike Mahan describes an “in vivo” antibiotic test that mimics conditions in the body. Drugs that pass the standard test often fail to treat bacterial infections, whereas drugs identified by the test are very effective. Recorded on 07/24/2017.

From KETC, LIVING ST. LOUIS Producer Ruth Ezell recently spoke with Dr. J. Eugene Lewis, a 1942 Harvard Medical School graduate and veteran of World War II. From shamans and medicine men to modern doctors, healers have often found themselves where patients are plentiful—on the battlefield during times of war. Lewis's career as a doctor was shaped by the times in which he was trained. As a member of one of the army's first mobile medical units serving in Normandy, Lewis practiced his trade in an environment where supplies were scarce, shock was a relatively new condition and penicillin was the cutting-edge wonder drug. "Although it might seem mundane now, the work of physicians during World War II paved the way for modern medicine," Ezell says. "Lewis's experiences were revolutionary at the time. They created the circumstances where innovations such as the widespread use of antibiotics and the modern M.A.S.H. unit were born."

Antibiotic resistance is rampant in the world, and we are moving towards dark ages when it comes to curing something as simple as a cut or a wound. Hear one of the leading experts in the field of resistance talk about what the problem is, how we can handle it and what human kind should do to protect one of our most valuable discoveries - Antibiotics. Dag Berild is a professor and a senior consultant in infectious diseases at both the University of Oslo and Oslo University College. Berild’s research concerns the rational use of antibiotics and his aim is to prevent antibiotic resistance, and to strengthen doctors’ knowledge on antibiotics so that they in turn can improve antibiotic use and reduce this resistance. He has conducted several intervention studies to improve antibiotic use both in Norway and in Russia, and also heads the Study Group for rational antibiotic and trough his day-to-day work. In this talk he will explain why this matters, and paint a scary picture of a world without a cure if we do not start to adjust our thinking now. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx

www.arcimedia.com.au The untold story of the history and making of Penicillin. In 1940, as World War Two raged, Australian Howard Florey and team at Oxford University made the worlds first antibiotic. They used old bedpans, parts of a broken telephone and scrounged dairy equipment. Penicillin was a lifesaver, but its discovery was a trial of penury, character assassination and spotlight snatching. Using dramatic re-enactments and Florey's own archive film, this documentary tells the true story. An intriguing and captivating watch guaranteed to keep you hooked from start to end.

As current antibiotics begin to lose their punch, there’s an economic reality putting a damper on development. Since every use of an antibiotic drives resistance, and doctors are reluctant to use a drug until there's no alternative, why would a drug company spend a fortune? Economics correspondent Paul Solman and science correspondent Miles O’Brien continue their look at the hunt for new drugs.

A growing number of infections are antibiotic resistant. Antibiotic-resistant infections are spreading between healthcare facilities, even those that are practicing infection control and antibiotic stewardship. By adopting a coordinated approach, however, where multiple facilities in an area work together to improve infection control and stewardship activities, we can reduce the spread of antibiotic-resistant infections and protect patients.

Light-activated nanoparticles, also known as quantum dots, can provide a crucial boost in effectiveness for antibiotic treatments used to combat drug-resistant superbugs such as E. coli and Salmonella, new University of Colorado Boulder research shows. Multi-drug resistant pathogens, which evolve their defenses faster than new antibiotic treatments can be developed to treat them, cost the United States an estimated $20 billion in direct healthcare costs and an additional $35 billion in lost productivity in 2013. Researchers in the BioFrontiers Institute, however, were able to re-potentiate existing antibiotics for certain clinical isolate infections by introducing nano-engineered quantum dots, which can be deployed selectively and activated or de-activated using specific wavelengths of light. Rather than attacking the infecting bacteria conventionally, the dots release superoxide, a chemical species that interferes with the bacteria’s metabolic and cellular processes, triggering a fight response that makes it more susceptible to the original antibiotic. Going forward, the researchers envision quantum dots as a kind of platform technology that can be scaled and modified to combat a wide range of infections and potentially expand to other therapeutic applications.
