Any horse owners interested in obtaining equine rotavirus vaccine should contact their state veterinarian (http://www.TheHorse.com/ViewArticle.aspx?ID=3251) and request release of the vaccine in their state. VEE symptoms are similar to those off EEE and WEE. The statistical significance of the differences between vaccine groups was determined by a nonparametric one-way analysis of variance (Kruskal-Wallis Test) with Dunnett’s post test (GraphPad InStat, version 3.0; GraphPad Software, San Diego, Calif.). Quantitative and qualitative serological analyses. Transporting horses and ponies should always be as safe and stress free as possible and in line with rules about animal welfare during transport. Pregnant mares in high-risk areas should be receive a primary series at least four to six weeks prior to foaling to ensure transfer in colostral antibodies for the foal. However, the underlying mechanisms responsible need further investigation.

Pathogenesis of equine herpesvirus 1 and 4″ viraemia, neuropathology, cell mediated immu- nity and latency Slater JD, Slade, A, Field HJ Collaborators: Borchers K, Steinbach F, Wolfinger U, Ludwig H, Free University of Berlin. The tail is often held out straight and the horse develops an anxious expression because of facial muscle spasm. 2nd vaccination: To be given 4-6 weeks after the 1st vaccination. Management of Twin pregnancies. Comparison of in vitro (in the laboratory) antiviral activity of herpesvirus DNA polymerase inhibitors against neuropathogenic and non-neuropathogenic strains of EHV-1. Must not compete in the 7 days after receiving a vaccination. Furthermore, the method of administration of DNA vaccines (multiple sites of inoculation and multiple injections for each immunisation) is obviously impractical for veterinary practice.


Revaccination is carried out every three months to maintain immunity. Other vaccines exist for herpes, rotavirus and EVA (equine viral arteritis). Aimee Nielson is an agriculture communication specialist in the UK College of Agriculture, Food and Environment. How do I know if my horse has sweet itch? Horses and ponies that have teeth with sharp and uneven edges often develop injuries in the mouth and have difficulty chewing as well as problems accepting the bit. The symptoms and clinical signs of equine viral rhinopneumonitis are more severe in younger foals where death can occur within just one day. Another striking feature is that the recent neuronal cases of EHV-1 infection in both Virginia and Ohio occurred despite regular vaccinations in very short intervals, indicating the possibility of the circulation of EHV-1 variants that are able to break vaccine protection ( http://www.thehorse.com , article numbers # 3683, 4104, 4127 and 4272).

This is a highly contagious respiratory tract infection that spreads by direct contact between horses and ponies. Recommendations for vaccinations vary according to the data sheets from the vaccination companies, FEI guidelines (the international governing body of equestrian sports) the British Horseracing Authority Rules (formerly known as the Jockey Club) and stipulations from individual shows, e.g. Once infected, many horses become carriers which means they will shed the virus, infecting other in-contact horses. All horses that were certified as correctly vaccinated under the previous FEI Equine Influenza vaccination rule prior to 1st January 2005, do not need to start a primary course again provided that they have complied with the previous rule of primary course and annual re-vaccinations and the new rule of a booster vaccination within 6 calendar months + 21 days of the day of arrival at the FEI event. What will happen if my horse is infected with EHV? WNV vaccination should have no significant impact upon WNV surveillance studies. Depending on the brand of vaccine used, booster doses may only be needed as infrequent as every 2 years.

The study demonstrated a strong evidence of broad-based horse exposure to a variety of leptospiral variations across the United States and Ontario. Vaccination against ‘flu is often a requirement for entry into livery yards and competitions. Rotavirus is a viral infection that causes diarrhoea in foals. All horses and donkeys should be vaccinated against tetanus, which is usually a fatal condition in the horse. Excitement or stress can often cause shedding – horses travelling to events/competitions are particularly at risk. EHV occurs throughout the UK. EHV is spread from horse to horse, mainly through the infective virus being coughed into the air and inhaled by other horses close by.

However, the initial ingestion of colostrum (the mare’s antibody-rich first milk) allows for passive transfer of immunoglobulins, which provide almost immediate immunity against various infections, all dependent upon quantity and quality of the maternal antibodies. The intent of this rule is to ensure that all licensed competitions comply with the vaccination guidelines for equine influenza and rhinopneumonitis published by the American Association of Equine Practitioners (AAEP). The current drama is being produced by research involving DNA vaccines. Immune responses to vaccine antigens were measured on Day 56. Methods: Lymphocytes from 200 Thoroughbred horses were stimulated with EHV-1 in vitro, and IFNγ detected using a monoclonal antibody and indirect immunofluorescence.
