As much as public health officials have tried to slow the progress of antibiotic resistance, the pace has not slowed.

American researchers have recently revealed one of the ingredients in milk may be necessary for the growth of Clostridium difficile bacteria.

A need exists for rapid change in the social mindset of the next generation on antibiotics. If our youth do not appreciate the challenges facing public health officials today, they may end up living under the shadow of untreatable bacterial infections known as the post-antibiotic era.

If we can prevent infections before they begin, we can reduce the amount of antibiotics used in medicine. In light of the wide array of uses already known - and possibly more to come - we may have a simple yet effective way to use our own natural chemistry to keep us safe.

As Mother's Day approaches, Canadians will be celebrating the people who brought us into this world and nurtured us as we developed. Most of the adulation will be due to social graces, such as care, kindness, and those life lessons that always come in handy. But there are other reasons -- specifically molecular -- making Mom a baby's best ally.
We are facing an antibiotic resistance crisis. Almost every health authority has sounded the alarm and the most recognized authority, the World Health Organization, is doing all it can to slow the arrival of the post-antibiotic era. Yet, even as these calls are made, the use of these drugs continues to be unacceptably high.

"I was certain that I was going to die," said 25-year-old Ifrah in Somaliland, of her battle with tuberculosis. It's not something we should be hearing in 2017. An illness old enough to have been known as 'consumption' or 'The White Plague' should have its place in medical history -- not claiming 1.8 million lives a year.

At its core, antibiotic resistance is merely a coping mechanism. Bacteria are faced with a rather dire form of stress and need to find a way to cope. They can take the biological route of genetic mutation to render the drug useless. They also can gain a plasmid from the environment or another bacterium, to gain resistance mechanisms.

The concept of tolerance isn't relevant only in the microbial world. All biological life has the ability to tolerate, including humans. A perfect example of this phenomenon occurs in those able to eat hot, spicy foods. You might think they are simply born with stronger tongues. But that isn't the case. Instead, in most cases, a biochemical modification has occurred in one of the proteins found on the tongue.

Meat isn't what it used to be. What's typically sold in supermarkets isn't what our ancestors ate. And it sure isn't as healthy. But there's no need to despair. If you pay a little extra, these days you can find organic, traditionally-farmed meat.

Imagine a not-too-distant future where the survival of mankind hangs in the balance because modern medicine's frontline defenders -- antibiotics -- are being outsmarted by deadly microscopic enemies. I'm talking about the emergence of so-called "superbugs." They're real, they exist, and if you eat non-organic chicken, then you're all the more at risk.

At first glance, obesity may appear to be an easy problem to resolve. After all, most people may believe the answer lies in eating fewer calories and exercising more. While these are definitely helpful, obesity is an incredibly complex issue, and involves a number of factors ranging from genetics to socioeconomic status. So can antibiotics help?

The mere mention of nanotechnology may raise eyebrows. Yet worries should not be based on size but molecular composition instead. If a particle is made from plastic or heavy metals, concern is definitely valid. However, polylactic acid nanoparticles are biodegradable, making them perfect for use both in the environment and also in the body.

A few months ago, the discovery of the antibiotic resistance gene mcr-1 sent shockwaves through the public and the health communities. This piece of bacterial DNA, also known as plasmid-mediated colistin resistance, revealed bacteria had developed a mechanism to tolerate yet another antibiotic.

Antibiotics have no effect either.

A Finnish group of researchers released the results of a three-year study examining the effects of long-term probiotic use on antibiotics and children's health. The results suggest probiotics may offer far more than a means to prevent AAD and C. difficile. They may actually help to reduce the need for antibiotics in the future.
In the arms race between germs and medicine, the global community has two complementary strategies at its disposal: First, we can develop new antimicrobials, and secondly, we can slow the emergence of resistant strains through judicious use of current antimicrobials.

It's been nearly two years since the World Health Organization called the rise in antibiotic resistance a crisis. Since that time, public health officials have sought new answers to prepare for an uncertain future. While the idea of making new and stronger antibiotics continues to explored, its popularity has faded.
Last week, an international team of researchers revealed how bacteria in the oral cavity may be able to withstand even the hardest toothbrushing. Their research showed just how stable certain species can be and suggested the cure may require a more ecological approach.

For many Canadians, no turkey dinner is complete without the addition of cranberry sauce. The tartness from the red berries offers a perfect complement to the rich meal. But beyond these special moments, cranberries have long been thought to be an excellent way to improve health, particularly in the urinary tract.

If you are one of the over 6 million Canadians suffering from irregular heartburn or stomach ulcers, you're probably familiar with proton pump inhibitors, or PPI. But new research suggests a non-trivial link between these commonly-prescribed heartburn medications and increased risk of infection, all because of one specific stomach bacteirum. Let's investigate.

The World Health Organization has led the charge to raise awareness and ensure the public understands the looming crisis of what is commonly known as the post-antibiotic era. In essence, we may be forced to return to a world in which these life-saving medicines are no longer effective.

Despite all the technology in academic and pharmaceutical institutions, nothing can stop a microbe from figuring out how to best an antibiotic. As such, the mood is sombre at best and apocalyptic at worst. Instead of trying to develop yet another complex mousetrap, the answer lies in looking at weapons of mass microbial destruction already in use in the wild.

The doctor said my mother was "colonized" by antibiotic-resistant bacteria. The bacteria didn't actually make her sick, but the doctor said the germs might spread to other patients. It seemed to be a lot of fuss over nothing. Did the hospital overreact?
One of the best places to look for alternatives is nature. Antibiotics were first discovered in natural species -- fungi to be exact -- and a number of options for the future have been found. Now it seems there is another possible option worth exploring: turmeric.
One of the primary goals in understanding how the bacterium used its toxin to cause disease focused on the nature of bacterial growth in the body. After all, not everyone who was exposed ended up with illness. The first major discoveries revealed the toxin was not produced all the time.
For those studying this unique branch of terrestrial life, the identification of resistance genes in the environment suggested there had to be antimicrobials out there. If this was the case, the Archaea were going to play a role. The only question they couldn't answer was the nature of this role. This past week, a team of researchers from Vanderbilt University may have provided the answer: Horizontal Gene Transfer (HGT).
