Vet Advice: New regs to preserve old and new drugs

By
I’m often asked why even older antimicrobials are still considered medically important to human medicine. The premise, right or wrong, is to preserve antibiotic effectiveness by reducing the risk of antimicrobial resistance attributed to wholesale use in animal agriculture. While debate still rages over the impact new legislation will have on preserving antimicrobial effectiveness in […] Read more

New drug regulations require adjustment

Vet Advice with Dr. Ron Clarke

No issue over the past 15 years occupied more space in agriculture, veterinary or public health-related press than antimicrobial resistance (AMR). No single topic appears more often on conference and seminar agendas than topics addressing the use, abuse and prudent use of antimicrobials in humans and animals. Petitions, a plethora of committees of every description, […] Read more

Facts about antimicrobial resistance

While the industry is already doing a good job, there is ongoing room for improvement

By
There have been volumes written on antimicrobial resistance (AMR) in the last several years. And it is important to remember just how good the Canadian cattle industry is doing in managing AMR and look to future changes veterinarians may make in their recommendations. For those of you craving more detailed information, there have been several […] Read more

Fighting AMR: A true test of human resilience

By
The ongoing explosion of antimicrobial-resistant infections continues to plague global health care. Our inability to mount significant countermeasures to resistance, while at the same time enduring the decline in research and development of new antibiotics creates a “perfect storm” and the fear we may be on final approach to a pre-antibiotic era of serious and […] Read more

Criteria for selecting the right antibiotic

There are a lot of factors at play and all of them need to be 
considered in every case where antibiotics are an option

By
Although a few very effective antibiotics have been removed from the marketplace over the years, the choice has never been greater. The challenge is there are so many factors hinging on the outcome, so deciding which antibiotic to use — or if one is necessary at all — can be a very difficult decision. Also […] Read more

Regulatory changes would limit farmers’ vet drug imports

Proposed Health Canada changes will affect how antimicrobials are imported into Canada

By
For John Prescott, a move to end farmers’ right to import certain veterinary drugs marks a significant turning point in the fight against antimicrobial resistance in Canada. The Public Health Agency announced last year that Health Canada’s Veterinary Drugs Directorate would introduce new regulations requiring veterinary oversight of antibiotics used in food animals, such as […] Read more

The AMR Dilemma: Part 2 – The impact

Finding the missing pieces to the puzzle of antimicrobial resistance

By
Although accurate statistics are difficult to tabulate, over two million people in North America become infected with bacteria resistant to antibiotics annually. At least 23,000 people die as a direct result of these infections. Virtually, all significant bacterial infections in the world are becoming resistant to the antibiotic treatment of choice. Health authorities in North […] Read more

Searching for ways to move forward on antimicrobial resistance

No issue in the past 15 years logged more space in agriculture, veterinary or public health-related press than antimicrobial resistance (AMR). No single topic appears more often on conference and seminar agendas than the one addressing prudent use and abuse of antimicrobials in humans and animals. Despite the attention AMR has received, we have not […] Read more

Conjugation, and what it means for antimicrobial resistance in livestock

By
The federal government’s CIPARS program studies E. coli in healthy cattle entering packing plants and in retail ground beef. Its surveillance shows that resistance to antimicrobials of the highest importance in human health continues to be very rare in these samples, and multi-drug-resistant bacteria are even less common. The risk of consumers being exposed to […] Read more

Tracking resistance to drugs in cattle bugs

It’s on the increase

By
The warning sign went up as results came in from two Alberta projects exploring the susceptibility of bacteria involved in bovine respiratory disease (BRD) to available antimicrobials. Alberta Beef Producers (ABP) administered the year-long project testing for antimicrobial resistance in feedlot cattle in order to develop an in-province screening tool. The project involved several industry, […] Read more
