Topic:Disease Prevention
Disease prevention in horses encompasses strategies and practices aimed at minimizing the occurrence and spread of infectious and non-infectious diseases within equine populations. These practices include vaccination programs, biosecurity measures, and regular health monitoring. Vaccination helps to stimulate the horse's immune system to protect against specific pathogens, while biosecurity measures, such as quarantine and sanitation, reduce the risk of disease transmission. Regular health monitoring, including physical examinations and diagnostic testing, aids in early detection and management of potential health issues. This page compiles peer-reviewed research studies and scholarly articles that explore various methods and their effectiveness in preventing diseases in horses, as well as the development and implementation of prevention programs in different equine settings.
Efficacy of Japanese encephalitis vaccine in horses. The efficacy of Japanese encephalitis vaccine in horses has been described from the effect of mass vaccination on the local prevalence of the disease in horses in each district of Hokkaido, Japan.
A practical health programme for prevention of parasitic and infectious diseases in horses and ponies. A scheme of combined anthelmintic treatment and vaccination is described. The seasonal veterinary activities are as follows: March (all horses); parasitological examination of faeces, anthelmintic treatment, immunization against influenza and tetanus (booster dose). June: parasitological faeces examination of foals, anthelmintic treatment of all horses, immunization of foals against tetanus (1st dose). August: anthelmintic treatment of all horses and immunization of foals against influenza (1st dose) and tetanus (2nd dose). October: parasitological faeces examination and anthelmintic treatment...
Experience of the efficacy of equine influenza vaccinations. In 1974, a very extensive influenza/A/equi 2 epidemic broke out in the Finnish horse population. To study the efficacy of influenza vaccinations a questionnaire was sent after the epidemic to all Finnish veterinarians. The answer material was selected to contain only stables which had had clinically typical cases. The material consisted 234 unvaccinated and 629 vaccinated horses. In the latter group 466 horses were vaccinated adequately. The results of the study showed that of the unvaccinated horses 212 (91%) and of the adequately vaccinated horses only 42 (9.4%) contracted clinically typical...
Equine viral encephalitis. The most important neurotropic viral infections of the horse are the arthropod-borne encephalitides. These include Venezuelan encephalitis (VE), eastern encephalitis (EE) and western encephalitis (WE), which are found in the Americas, and Japanese B encephalitis which occurs in the Far East. All the viruses cause encephalitis in man. Between 1969 and 1972 an epidemic of VE occurred in Central America. In 1971 the disease was reported in Texas, where it was brought under control by the vaccination of susceptible horses with an attenuated live virus vaccine and by the reduction of the mosquito p...
Practical aspects of equine virus abortion in the United Kingdom. The current knowledge of the clinical signs, epidemiology and pathogenesis of abortion due to the equid herpesvirus (EHV 1) is reviewed. The relationship between the respiratory and abortigenic forms of the disease is discussed as well as the low incidence of virus abortion in the UK compared to some other parts of the world. Some practical aspects of the disease as they affect stud management are considered including methods of diagnosis, prophylaxis and the necessary action to be taken to prevent spread of infection.
The pregnancy protecting effect of progesterone against human chorionic gonadotrophin challenge in mares. 14 pregnant Welsh Mountain Pony mares were treated with progesterone in an effort to prevent pregnancy failure induced by administration of human chorionic gonadotropin (GCG). 13 of the 14 mares were treated with progesterone by injection or implant before the 38th day of pregnancy. HCG was given in 3 doses on alternate days at a dose rate of 2000 imc/day. The remaining mare was treated with HCG toward the end of the experiments to demonstrate the abortifacient property of HCG. 3 mares aborted and 1 of these was anovulatory thereafter. Further research is needed to determine the effective prog...
Transmission of equine infectious anemia virus by Tabanus fuscicostatus. The mechanical transmission of equine infectious anemia (EIA) virus by Tabanus fuscicostatus was investigated. In 1 of 7 transmission trials, a single horsefly transmitted EIA virus from an acutely infected pony to a susceptible pony. Groups of horseflies isolated for 3, 10, or 30 minutes before refeeding transmitted EIA virus, whereas those isolated for 4 or 24 hours did not. Data from field studies indicate that the home range or flight distance of horseflies may exceed 4 miles. That information together with our observations suggest that segregation of infected horses (usually defined as at...
Vaccination by the non-parenteral route of virus disease in the veterinary field. After a brief reference to the importance of the non-parenteral route of vaccination of domestic animals in general, the author deals, for each animal species separately, with the most important vaccines utilised by this method of administration. On the basis of bibliographical data, he describes the history of this use, discusses the results of the application in the field and draws the relative conclusions.
Immunization of man and animals against influenza by oral and intranasal routes. Live human and equine influenza virus strains modified by serial passage on allantois-on-shell system (AOS) in the presence of normal horse serum were administered orally or intranasally to volunteers or horses. Mostly mild clinical short-lasting reactions, replication in nasal mucosae, transmission to placebo recipients and significant local or circulating antibody rises were observed following administration to volunteers of strains modified by five or less serial passages on AOS in the presence of normal horse serum (NHS). Milder clinical reactions, no replication, no viral transmission and...
Immunity to Streptococcus equi. Using the long chain test, and in some cases the bactericidal test, to measure antibody, the development of the immune response in horses to Str. equi has been followed. Long chain indices in excess of 5.0, accompanied by strong bactericidal capacity, were recorded in serums after the full 3-dose immunisation course with a commercial vaccine. The full course elicited the most satisfactory antibody titres declined within the 12 month post-vaccination period, thus providing support for the recommendation that yearly booster doses should be administered. The immune response in horses during 2 str...
A field study of persistence of antibodies in California horses vaccinated against western, eastern, and Venezuelan equine encephalomyelitis. As a result of the continuing threat of Venezuelan equine encephalomyelitis (VEE), a study was made to determine if revaccination against VEE (TC-83 vaccine) was feasible and if revaccination could be incorporated into other routine vaccination practices. Of the horses given annual vaccination with bivalent western equine encephalomyelitis (WEE) and eastern equine encephalomyelitis (EEE) vaccine, 57% retained detectable serum-neutralizing (SN) antiboyd titers for VEE 18 months after the initial VEE vaccination was given. Of horses with no record of WEE-EEE vacinnation, 100% retained detectable...
Babesiosis in the newborn foal. A short account is given of babesiosis (equine biliary fever) caused by the tick-borne protozoan Babesia equi and B. caballi, endemic in the Cape Province of South Africa. The clinical picture, diagnosis and treatment are described. In the absence of any prophylactic measures, prognosis is poor; control of the parasites in the tick-infested areas is essential.
