Antimicrobial chemicals found with antibiotic-resistance genes in indoor dust

Researchers have found links between the levels of antimicrobial chemicals and antibiotic-resistance genes in the dust of an aging building used for athletics and academics. One of the antimicrobials seen in the study is triclosan, a commonly used antibacterial ingredient in many personal care products.

Experimental antibiotic treats deadly MRSA infection

The antibiotic arms race is on, while we are rushing to find new antibiotics, bacteria are working on finding ways around them. With that in mind, a new experimental antibiotic developed by a team of scientists successfully treats the deadly MRSA infection and restores the efficacy of a commonly prescribed antibiotic that has become ineffective against MRSA.

Antibiotic resistance, evolution, and our future

Without the discovery of antibiotics we could not — and most certainly would not — be living in the world we do today. It was a discovery that would save countless lives, while simultaneously compromising our future. From the use (and unfortunate misuse)  of antibiotics, we gave rise to more virulent bacteria that have become resistant to more and more types of antibiotics.

Testing the evolution of resistance by experiment

When the first antibiotics became available 70 years ago, they were often described as miracles of human ingenuity, rather like plastics or bright permanent dyes, which were discovered at roughly the same time. Packaged in vials or pills, they seemed like our inventions rather a chance gift of evolution and one that evolution might also rescind.

Alternatives to antibiotics in an antibiotic resistant world

Let’s be honest, we’ve been getting a little fancy with the antibiotics, creating new and more relevant versions of old favorites like penicillin. Truthfully, we are the problem, how many times do we have to drive home the idea that antibiotics are for bacteria, not viruses. It is not all the consumers fault, the Doctors used to hand out antibiotics to placate angry parents of sick children.

New antibiotic may help slow drug resistance

probiotics-vs-antibiotics

Antibiotic resistance, a hot topic lately here at the labs, as evidence by this recent post. So it is fortuitous that I stumbled upon this little bit of research that suggests scientists (using a “revolutionary” approach) have devised an antibiotic that may offset the mounting problem of drug resistance for decades… hopefully.

Using “Programmable” Antibiotics to Attack Drug-Resistant Microbes

The body is pretty great at self regulation, that is up until it isn’t. The antibiotic era was one that improved human health hundreds of times over. Unfortunately health is a joint effort, a multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating brute force of traditional antibiotics, which wipe out everything at once like a wild fire, regardless of the consequences.

The Path of Antibiotic Resistance

MRSA, not that long ago we had no idea what MRSA was… mostly because it hadn’t come into prevalence. With an increase in the use and abuse of antibiotics there has been an ever growing pressure for the pathogens we treat to mutate in order to survive, this pressure is called selective pressure and helped cause drug-resistance in pathogens. In response to the rise of these drug-resistant pathogens, doctors are routinely cautioned against over prescribing antimicrobials. But when a patient has a confirmed bacterial infection, the advice is to treat aggressively to quash the infection before the bacteria can develop resistance.
