Circadian rhythm research applies to livestock health

This year’s Nobel Prize for Physiology or Medicine was awarded to three researchers who studied the internal biological clock that regulates day and night cycles in sync with the Earth’s rotation. Jeffrey C. Hall, Michael Rosbash and Michael W. Young were jointly awarded the prize for their discovery of molecular mechanisms controlling this circadian rhythm. […] Read more


Co-infections have major influence on infectious diseases

Animals are infected by more than one infectious agent at a time in natural settings. Thus, co-infections are the norm rather than the exception. However, since the scientific revolution that tied microscopic infections to disease — the “germ-theory” of disease — most re-searchers have focused on one pathogen infection at time. This was a reasonable […] Read more


Lungworm issues can be difficult to diagnose

Parasites that live in animals’ digestive tracts are the most frequent and arguably the most important parasites to infect animals. However, parasites can occupy a variety of organs in the body, including the skin, brain and kidney. A lesser-known class of parasites are those that reside in the lungs and windpipe. These lungworms affect a […] Read more



Plastic in ecosystem harms wildlife, environment

A vast, heaving mat of plastic bobs on the waves in a bend of the Grijalva River within the Sudidero Canyon of Chiapas, Mexico. The one kilometre towering cliffs, diverse wildlife and thick rainforests of Mexico’s Grand Canyon are just as striking as the plastic bottles and other debris choking the waterway. This is one […] Read more


Canker: a rare hoof condition requiring early treatment

Hoof canker is an unusual condition in horses. The rare disease results from abnormal growth of the outer horn layer of the hoof It typically originates in the frog, the bottom portion of the hoof toward the heel. In severe cases, canker can spread to the adjacent sole, hoof wall and bars. Horses with canker […] Read more



Emerging fungal diseases threaten wildlife

It isn’t often we focus on fungal diseases; usually viruses and bacteria occupy our attention when it comes to infectious diseases. But fungal infections are on the rise. Particularly in wild animals, fungi are a major cause of newly recognized infectious diseases. White nose syndrome, a fungal infection of hibernating bats, is demolishing populations in […] Read more


Keep horses healthy and safe during summer travel season

With spring underway, equine events are beginning to pop up on calendars across the country. Whether you travel with your horse for a local trail ride or head to a big competition, there are health and safety considerations to take into account before leaving home. Whenever horses gather together from different properties, a risk of […] Read more


Clostridium difficile a major cause of diarrhea in animals

Like many other bacterial species, Clostridium difficile, often referred to as C. diff, lurks in the guts of animals waiting for the chance to strike. It lives peacefully amid a teeming community of other types of bacteria until something puts the gut ecosystem into disarray. Usually the disruptor is a blast of antibiotics that kill […] Read more



International horse trade raises risk of infectious disease

For centuries, people have taken their domestic animals, and the diseases they carry, around the world. Spanish conquistadors brought herds of horses on ships from the Old World to North America. Those that escaped or were set free became the founding populations of the familiar North American breeds including the feral mustangs, Appaloosas, Paints and […] Read more


Bartonella an increasing pathogen affecting people and animals

In the First World War, soldiers were afflicted by a new illness called trench fever. The condition was characterized by re-curring bouts of fever, dizziness and head, lower back and shin pain that sidelined soldiers for months. It wasn’t until the end of the war that a tiny bacterium, called Bartonella, was identified as the […] Read more
