Reaction result is expressed as the smallest amount of antigen which causes complete inhibition of hemagglutination.Trichlorfon: An organochlorophosphate cholinesterase inhibitor that is used as an insecticide for the control of flies and roaches. It is also used in anthelmintic compositions for animals. (From Merck, 11th ed)Performance-Enhancing Substances: Agents that improve the ability to carry out activities such as athletics, mental endurance, work, and resistance to stress. The substances can include PRESCRIPTION DRUGS; DIETARY SUPPLEMENTS; phytochemicals; and ILLICIT DRUGS.Equine-Assisted Therapy: Therapy assisted by the use of a horse and/or its movement, including equine-assisted psychotherapy, horseback riding, and hippotherapy.Herpesviridae: A family of enveloped, linear, double-stranded DNA viruses infecting a wide variety of animals. Subfamilies, based on biological characteristics, include: ALPHAHERPESVIRINAE; BETAHERPESVIRINAE; and GAMMAHERPESVIRINAE.Endophytes: An endosymbiont that is either a bacterium or fungus living part of its life in a plant. Endophytes can benefit host plants by preventing pathogenic organisms from colonizing them.Spectrophotometry: The art or process of comparing photometrically the relative intensities of the light in different parts of the spectrum.Gait: Manner or style of walking.Actinobacillus equuli: A genus of gram-negative bacteria in the genus ACTINOBACILLUS, which is pathogenic for HORSES and PIGS.Amino Acids: Organic compounds that generally contain an amino (-NH2) and a carboxyl (-COOH) group. Twenty alpha-amino acids are the subunits which are polymerized to form proteins.Nematode Infections: Infections by nematodes, general or unspecified.Sodium Acetate: The trihydrate sodium salt of acetic acid, which is used as a source of sodium ions in solutions for dialysis and as a systemic and urinary alkalizer, diuretic, and expectorant.Diet: Regular course of eating and drinking adopted by a person or animal.Liver: A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.Muscular Diseases: Acquired, familial, and congenital disorders of SKELETAL MUSCLE and SMOOTH MUSCLE.Locomotion: Movement or the ability to move from one place or another. It can refer to humans, vertebrate or invertebrate animals, and microorganisms.Muscle, Skeletal: A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.Tripelennamine: A histamine H1 antagonist with low sedative action but frequent gastrointestinal irritation. It is used to treat ASTHMA; HAY FEVER; URTICARIA; and RHINITIS; and also in veterinary applications. Tripelennamine is administered by various routes, including topically.
