Vaccination elicits a prominent acute phase response in horses.

European and American guidelines for vaccination against tetanus and influenza in horses recommend annual and annual/semi-annual vaccinations, respectively, against the two pathogens. Too-frequent vaccination may, however, have adverse effects, among other things because an inflammatory response is elicited with subsequent alterations in homeostasis. The objective of the study was to compare the acute phase response (APR) in 10 horses following administration of two different types of vaccines, namely, an inactivated Immune Stimulating COMplex (ISCOM) vaccine and a live recombinant vector vaccine.

Colour doppler ultrasonography and sclerosing therapy in diagnosis and treatment of tendinopathy in horses-a research model for human medicine.

Sclerosing therapy has in recent studies showed promising results in patients with clinically and ultrasonographically diagnosed tendinosis in Achilles and patellar tendons. The aim of this investigation was to study the presence of intratendinous colour Doppler (CD) flow in horses with clinically diagnosed chronic tendinopathy and to test if experience from human studies could be extrapolated to horses. Special interest was focused on the treatment with sclerosing therapy and whether we could obtain the same successful peroperative findings as in humans.

Risk factors for the hazard of lameness in Danish Standardbred trotters.

A follow-up study focusing on health problems interfering with optimal training of Danish Standardbred trotters was conducted with the participation of seven professional trainers. Our aim was to estimate the incidence of health problems that cause interruptions of optimal training, and to identify associations between the hazard of lameness and selected risk factors. The study population was dynamic and contained data of 265 Standardbred trotters monitored during 5 months in 1997 and 1998.
