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.
Equine plasma banking: collection by exsanguination. A procedure was developed for the collection, preparation, storage, and administration of equine plasma. The technique involved exsanguination of anesthetized donor horses via carotid artery catheterization with a large-bore cannula. Blood was collected into plastic bags, allowed to settle by gravity, then transferred into storage bags and frozen. These were quickly thawed when needed.
Control of cyathostome infections in mares treated at parturition with ivermectin. Six mares were treated on the day of parturition with an intramuscular injection of 0.2 mg kg-1 ivermectin and placed in a pasture free of equine parasites as soon as possible after foaling. The mares and their foals were compared with a similar group of untreated mares and foals on an adjoining pasture. The experimental data was derived from mare and foal fecal egg counts, foal necropsies and pasture larval counts. Ivermectin administered to mares on the day of parturition, when combined with movement to parasite-free pastures, significantly lowered the cyathostome (small strongyle) egg produ...
Research needs on internal parasites of horses. The importance of the horse industry to the economy of the United States and the impact of parasitic infections on the industry are well documented. However, contemporary research activity on internal parasites of horses has not kept pace with growth of the horse population. Parasitic infections are a major facet of enteritis and colic in horses. Parasites are also associated with poor growth and development, respiratory tract disease, dermatitis, and CNS lesions. Babesia infections remain a threat to horses imported from some regions of the world. Most research activity has dealt with the dev...
Serratia spp infection in 21 horses. Twenty-three isolations of Serratia spp were made from 21 horses at the University of Florida Veterinary Medical Teaching Hospital between Jan 1, 1979 and July 1, 1983. Three Serratia spp were involved in single-organism and mixed infections of various tissues. Eight horses of this group died. All horses that died had massive, mixed, gram-negative infection. The other 13 responded to treatment, including systemic antibiotic therapy. Most of these horses were stressed and under antibiotic therapy prior to the time of culture. Possible nosocomial infection, variable antibiotic sensitivity, and a...
Inhibitory substances in horse sera used in the preparation of microbiological culture media. The failure of N. gonorrhoeae to grow on isolation media was found to be due to inhibitory substances present in commercially available horse sera. Subsequent investigations indicated that the inhibitory action of the horse serum may have been due to antibodies to N. gonorrhoeae, H. influenzae, H. parainfluenzae and beta hemolytic streptococci. This experience highlights the need for media quality control programmes in laboratories which prepare microbiological culture media.
Antimicrobial drug susceptibility of bacteria isolated from disease processes in cattle, horses, dogs and cats. Results are presented of antimicrobial disc diffusion susceptibility testing on commonly isolated bacterial pathogens made at the Ontario Veterinary College Diagnostic Bacteriology Laboratory in 1981 and 1982. Nearly 2 000 isolates from horses, cattle, dogs and cats were tested. Comparison of resistance in the same bacterial species isolated from different animal species showed significant differences between some of the same antibiotics.
Some nutritional aspects of colic in horses. Consistency of exercise and diet are important in colic prevention. Water should be offered before and after feeding. Fast-growing foals suckling heavily lactating mares may overeat grain at weaning. Creep feeding to accustom the foal to eating grain and gradually increasing the grain intake after weaning are helpful in preventing colic in foals. Stallions may overeat grain when taken off pasture in hot weather. Feeding hay initially and grain later helps avoid colic in these stallions. Type-D Clostridium perfringens may cause enterotoxemia in foals. Corn should be fed in moderation. High-Mg d...
Vertical migration of infective larvae of equine strongyles in sandy clay loam. The migration of infective strongyle larvae through sandy clay loam soil was determined by evaluating the burial of horse dung as a method of reducing parasitism in horses. Equine feces containing 325 strongyle eggs/g of feces were buried at depths of 2.5, 5.0, 7.5, 10.0, 12.5, 15.0, 20.0, and 30.0 cm below the pasture surface in sandy clay loam soil. Herbage samples were taken periodically from above the buried feces and were analyzed to determine the maximum vertical migration of infective larvae. The greatest distance of migration was 20 cm which occurred 31 days after the feces were buried...
Standardization of the equine infectious anemia immunodiffusion test and its application to the control of the disease in the United States. In 1972 the US Department of Agriculture (USDA) established requirements that horses which had immunodiffusion antibody against equine infectious anemia could not be transported interstate. Forty-two states had regulations requiring that horses have a negative equine infectious anemia immunodiffusion test before movement. In order to standardize immunodiffusion testing, it was stipulated in the 1972 regulations that tests must be performed in approved laboratories. The approved laboratories were required to have personnel trained in the immunodiffusion test procedure, to follow the standard pr...
Cadmium and selenium levels in kidneys from Danish horses. The content of cadmium and selenium in horse kidneys from Jutland , Denmark, in relation to age, local geographical variation and possible relationship between the two elements has been investigated. During the winter of 1982-1983 kidneys from 50 horses were sampled and analysed for cadmium and selenium. The cadmium content of the horse kidneys was recorded in connection with the age of the horses. The cadmium level increases until the animal has reached approximately 7 years of age. At this age the cadmium concentration levels off. A significant regional difference was shown. The cadmium cont...
