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. Although only


Food safety for older adults

Health Canada is reminding Canadians of the importance of food safety for older adults. As we age, it becomes harder for our immune systems to fight off harmful bacteria. This means that older adults can come down with a serious illness if they eat contaminated food. For this reason, it is very important for older

Antibiotic resistance could be ‘apocalyptic scenario’

Antibiotic resistance “has the potential to undermine modern health systems,” and an “apocalyptic scenario may be looming if we don’t act now,” say scientists writing in the British Medical Journal. Current estimates suggest that antibiotic resistance is a relatively cheap problem, they write, but such estimates do not take account of the fact that antimicrobial


Washington demands better food safety practices

Reuters / U.S. regulators say proposed new food safety rules will make food processors and farms more accountable for reducing foodborne illnesses that kill or sicken thousands of Americans annually. “These proposed regulations are a sign of progress,” said Caroline Smith DeWaal, food safety director at the Center for Science in the Public Interest and

Soybean root rot pathogen breaks the rules

For every rule there’s an exception. Agriculture and Agri-Food Canada researchers have discovered a devastating soybean pathogen has developed a means of breaking Mendel’s laws, which sets out the rules on how genetic characteristics are passed on via inheritance. The discovery could lead to better control of soybean root rot disease, a major problem worldwide,


Warning issued over rodent infestations in vehicles

Rural residents are being warned that mouse infestations in parked vehicles pose a serious health hazard. Manitoba Public Insurance has seen a sharp jump in claims for rodent damage and MPI spokesman Brian Smiley says people need to take extreme care if there’s a chance those rodents were deer mice. “With deer mice there could

Chronic issues must be addressed

Every beef producer in Manitoba has a stake in seeing TB eradicated in the area around Riding Mountain National Park

Farm groups often bemoan the fact that it can be difficult to work with governments. You will also often hear associations complain that one department is pursuing objectives that are diametrically opposite to the initiatives of another branch of government. Unfortunately, these complaints often contain a grain of truth. However, it is also true that


Redwater — severity can vary by area

In talking with other veterinarians it is amazing to me how variable the prevalence of a specific disease can be between geographic areas. We always think of the huge difference between warm climates and colder, more temperate climates. Sometimes these differences can be as close as a one-hour drive in the same province. This becomes

E. coli resistance develops in the soil

Antibiotic-resistant E. coli will survive in the soil to recolonize in a cow’s gut through pasture, forage or bedding

Washington State University researchers have found an unlikely recipe for antibiotic-resistant bacteria: Mix cow dung and soil, and add urine infused with metabolized antibiotic. The urine will kill off normal E. coli in the dung-soil mixture. But antibiotic-resistant E. coli will survive in the soil to recolonize in a cow’s gut through pasture, forage or
