Pathobiology professor John Prescott and technician Vivian Nicholson found that foals can be protected from Rhodococcus by administering a special plasma solution to the young animals. Prescott and his team suspect that Rhodococcus escapes the foal immune system by hiding inside lung cells.

Ventipulmin (clenbuterol hydrochloride) is, and has been for two decades, the treatment of choice for the alleviation of the symptoms associated with chronic obstructive pulmonary disease (COPD) in horses. Acting in the same way as many human asthma products, Ventipulmin relieves the airway spasm seen in COPD and other respiratory problems. The product is available in a number of formulations (granules, syrup, injection, powder, powder combination with antibiotic) in order to facilitate treatment in both acute and chronic disease events.

Potomac horse fever (PHF), or equine monocytic ehrlichiosis, is an infectious disease of the horse's gastrointestinal tract. The clinical signs of PHF vary widely among individual cases. Most horses show colic, depression and reduced appetite. Others may develop a fever which may last only a few hours or may occur in cycles throughout the day.

Equine piroplasmosis (EP) is a disease of Equidae caused by protozoan parasites which invade the red blood cells, causing their destruction. Two species or protozoa, Babesia equi and Babesia caballi, are present in 90% of the world inhabited by horses. Only Canada, USA, Australia, Japan, England and Ireland are not considered to be endemic areas.

Pigeon Fever is infecting horses in several Utah locations and is expected to spread. The disease was first recognized in the Uintah Basin about the middle of June 2003 and appeared at several locations within a few days.

EPM is a disease that affects the nervous system of horses. Although many horses are exposed to the causative agent, Sarcocystis falcatula, clinical signs result from the migration of this agent into the central nervous system. These clinical signs vary from mild gait abnormalities or behavioral changes to severe seizures and paralysis.

A Novel Morbillivirus Pneumonia of Horses and its Transmission to Humans. On September 22 and 23, 1994, veterinary authorities in Queensland and at the CSIRO Australian Animal Health Laboratory were advised of an outbreak of acute respiratory disease in horses at a stable in the Brisbane suburb of Hendra.

This page provides background information about infectious agents that are important in outbreaks of upper respiratory tract disease among populations of horses. Infectious respiratory disease is a very common problem in many species including horses. This is particularly true for performance horses because disease can interfere with athletic activity. In a survey of horse producers in Michigan, respiratory disease was ranked as the most common medical problem of horses, and only colic was considered to be more important.

Potomac Horse Fever (PHF) or Equine Monocytic Ehrlichiosis is an infectious diarrheal disease seen most frequently in the late summer through early fall months. It was originally reported near the Potomac River in Maryland and Virginia, but today it can be found throughout the United States.

Haylage is one of the alternative methods of preserving hay when weather conditions prevent the drying of hay below 14% moisture content. Unfortunately, haylage is not recommended when feeding horses due to the danger of botulism.
