Document Summary

Any deviation from normal health in which there are marked changes in the body: physiological e. g. body temperature, intake, anatomical e. g. leg problems, chemical e. g. elevated stress hormones. Mechanical wounds (route for pathogenic invasion) Toxins chemicals (lead, nitrates), plants (hemlock, nightshade) Virus reproduces inside living cells of host; lacks cytoplasm and thus uses metabolic action of host to replicate; usually host and tissue specific; may pass directly or via vector. Bacteria microscopic; single celled; causes damage via production of toxins. Protozoa single celled; microscopic cells; larger than bacteria. Fungi single or multiple celled low order plants. Helminths: ticks biting pathway for other organisms, mites burrow into skin, worms tapeworms, roundworms, flukes infect liver. Metabolic: ketosis (hyperketonemia, azoturia (paralytic myoglobinuria) Nutritional deficiencies: se, fe, vit a. Morbidity: measurement of illness; number of individuals in a group that become ill, largest problem and cost in animal production. Record keeping is important to herd health management. Know when to treat again booster shots.
