Farmers need to be aware of the vast world beneath their feet — healthy plants depend on it

It just might be that the most important living beings on any farm aren’t found in the barn — but in the soil. Bacteria, mycorrhiza, fungi, nematodes and even earthworms are key to understanding and promoting plant growth, University of Manitoba soil scientist Mario Tenuta told the Manitoba Forage Seed Association’s annual conference in Winnipeg

Scientists create ‘genetic firewall’ for new forms of life

New York | Reuters — A year after creating organisms that use a genetic code different from every other living thing, two teams of scientists have achieved another “synthetic biology” milestone: They created bacteria that cannot survive without a specific manmade chemical, potentially overcoming a major obstacle to wider use of genetically modified organisms (GMOs).

Producers can save time and money by not having to bale or buy, then transport straw

Henry Holtmann reaches into a large pile of what looks like a cross between wood shavings and down feathers, then lets the soft fibres slip through his hands. “When you grab it in your hand, it’s like a brown fluff, that’s the best way to describe it; it’s not like sand and it’s not like

Antibiotic-resistant genes pass between bacteria

Solving the problem of increasing antibiotic-resistant organisms will require stakeholders to move beyond the blame game and collaborate

It’s a microscopic problem with huge repercussions, repercussions that could end a way of life humans have enjoyed for seven decades. Experts say that antibiotic resistance is on the rise, including resistance to antibiotics important to human health. “It is indeed a crisis, the evolution of antibiotic resistance is occurring at an alarming rate, outpacing

Hog barn workers carry drug-resistant bacteria even after they leave the farm

A small study of North Carolina hog barn workers turned up surprisingly high levels of persistent and resistant bacteria

A small-scale study of hog barn workers in North Carolina found nearly half carry livestock-associated bacteria in their noses, and that this potentially harmful bacteria remained with them up to four days after exposure. Researchers with the Johns Hopkins Bloomberg School of Public Health tested 22 workers over a period of two weeks during the


Probiotics, prebiotics and horses

When supplements or products containing live micro-organisms are fed to horses the products are called probiotics, and Latin names like Lactobacillus, Acidophillus, Entercoccus, Bifidobacterium, and Saccaromyces will appear on the product’s ingredients label. While prebiotics have a similar intention to probiotics they do not contain the actual micro-organisms, rather substances which have been extracted from

Probiotics could serve as alternative to antibiotics in pig feed

German researchers have found that piglets fed probiotic Enterococcus faecium showed reduced numbers of potentially pathogenic Escherichia coli strains in their intestines, the American Society for Microbiology says in a release. Researchers were looking for alternatives to antibiotics for reducing pathogens in the intestines of young pigs following the EU’s ban on using antibiotics as

Ottawa begins to roll out new food safety measures and rules

New rules call for more timely and detailed reporting of problems and labels to let consumers know when meat has been mechanically tenderized

Almost a year after announcing its intention to overhaul national food safety rules, the federal government has unveiled the first of many measures it plans to implement through 2014. Among the new measures going into effect on July 2 is mandatory labelling of steaks and roasts that have been mechanically tenderized — a process that


An E. coli bacteria that we don’t mind

A team from the University of Exeter, with support from Shell, has developed a method to make bacteria produce diesel on demand

Most E. coli are harmless or even beneficial, but the bacteria get a bad rap because of toxin-producing strains such as 0157:H7. Scientists at the University of Exeter in England are using E. coli to produce another toxic product, but in this case a good one — diesel fuel. According to the university release, the

Research project pinpoints cause of bison deaths

The preliminary results are in from a bison research project examining the post-mortem findings and pathogenic agents causing bison deaths in Alberta herds. Four veterinarians have examined the causes of 100 bison deaths in herds across the province. The research group is composed of four veterinarians — Drs. Burrage, Clark, Lewis, and Tremblay.
