Document Summary
Similar to humoural but without the antibodies: humoural/antibody production (extracellular) Antibodies stick to pathogen and attract immune cells. Antibodies can"t contact the pathogen if it is inside a cell. Respiratory - cilia, mucous layer, coughing: gi tract - acidity, mucins, vomiting/diarrhea. Pamps - what the immune system responds to. 5 signs: heat (calor, redness (rubor) o o o. Self vs non-self (autoimmunity, allergic reaction, disease tolerance) Eukaryotes - fungi, yeast, (protozoa), worms, arthropods: acellular - viruses, prions. Classification of bacteria: microscopic characteristics, macroscopic characteristics, molecular and genetic characteristics. Eukaryotes; range from facultative anaerobic to aerobic; chemotrophic. Developments in mycology - more susceptible population today than historically. Protozoa - coccidiosis (includes toxoplasmosis) - food poisoning. Helminths - have intermediate hosts o o o. Early veterinary medicine - founded on zoonoses o o. Access management: designate distinct zones - boundaries, single access point. Restricted access zones - greatest biosecurity risk o o o. Control traffic on and off farm, truck washes.
