Veterinary Medical Applications Lesson Title: Zoonotic Diseases TEKS Addressed in Lesson: 130.6. (c)(8)(D) Lesson Objectives: Students Will: Define zoonotic Classify conditions/diseases into one of four groups of zoonotic diseases Compare and contrast the effects of parasitic, viral, fungal and bacterial diseases Identify the factors that cause a particular disease as well as treatments and cures Conduct research using the Internet and print materials regarding a disease topic Write an integrated 3 page report regarding the disease topic Conduct an interview with a person who has specific knowledge of a disease Integrate anatomy and physiology of the body using artistically pleasing and anatomically correct diagrams Integrate mathematics concepts by graphing current disease statistics Create a proper bibliography for their report Understand how contagious diseases spread rapidly Key Terms/Vocabulary Alternative Therapy - A treatment used instead of a conventional treatment Infectious- likely to be transmitted to people, organisms, etc., through the environment. Direct Transmission- a transmission mechanism in which the infectious agent is transferred directly into the body via touching or biting or kissing or sexual intercourse or by droplets entering the eye or nose or mouth Indirect Transmission- a transmission mechanism in which the infectious agent is transferred to the person by a fomite of vector Chronic- persisting for a long time or constantly recurring. Vector- an organism, typically a biting insect or tick, that transmits a disease or parasite from one animal or plant to another Fomite- any inanimate object (veterinary tools, books, pens, etc) that can transmit infectious agents from one person to another Interest Approach/Anticipatory Set -Review traits of a healthy animal and an unhealthy animal. This will assist students in drawing conclusions upon animal illnesses. List 12 diseases on the board, these should be diseases that the students are somewhat familiar with. Then have students classify these diseases into either bacterial, fungal, viral or parasitic. How are these diseases alike? How do they differ? Are they treated the same? Are they contagious? What does zoonotic mean? Are all diseases zoonotic? What are some examples of diseases that are not zoonotic? Teaching Plan and Strategy Presentation of New Material Students should fill in their copy of the teacher presentation Principles of Diseases PowerPoint. - - Healthy vs. Unhealthy Animals Characteristics of infectious/zoonotic diseases Types of Zoonotic Disease o Symptoms o Transmission o Diagnosis o Treatment o Prevention Personal Safety Preventative Measures Activity/Application/Student Engagement/Laboratory Students should be assigned at least one zoonotic disease. Some diseases should be associated with small animals and some with livestock. Students should research the following information and create a presentation to share with the class. (Make sure to assign students their diseases so the same disease isn’t presentation twice. (Research should take no more than 1.5 hours) Suggested Disease Topics: Leptospirosis Foot and Mouth Brucellosis Encephalitis Heart Worm Ring Worm Black Leg Bot Fly Round Worm Liver Fluke Tape Worm Kennel Cough Parvovirus Coronavirus Distemper Upon completion of research and completing their presentation, students should present to the class. Peers should follow along and answer the following questions about each of the diseases Infectious Disease Research Assignment You will be assigned 1 disease to research for this project. - - You will have one day in the computer lab to research the disease You will have one day in class to create your brochure o Must have 6 complete sections o Sources must be cited You must be able to present information to the class without reading directly from the brochure. Know your information don’t just copy and paste it into your brochure. Be able to answer 2 peer questions on this topic. Your brochure must include: o o o o o o o o o o o o o Title Picture associated with disease What is the causative agent of the disease? Is it a bacterium, a virus, a fungus or parasite o If it is a virus, what are its characteristics (DNA, positive-strand RNA, negativestrand\RNA, or retrovirus? enveloped or naked? how large is it? does it form a provirus? Any unique characteristics of its multiplication cycle?). If it is eukaryote, is it a fungus, an alga, a protozoan, a platyhelminth, or a nematode? Is it multicellular or unicellular? What is its life cycle? B. History: How long have we known about this disease? o Describe the changes in our knowledge and attitudes toward this disease throughout history. Epidemiology: Describe the prevalence and transmission of this disease. o Where (in the world) is the disease prevalent? How many people are currently infected? What is (are) the reservoir(s) of the pathogen? What is (are) the mode(s) of transmission? o Pathology: Describe the pathogenic effects on cells, tissues, and organ systems. Where in the body (what tissues/organs/cells) does the pathogen affect? What damage does the pathogen inflict? How is this damage inflicted (is there direct mechanical damage? is a toxin produced? does the immune response cause damage?)? What is the time sequence of the disease What are the major signs and symptoms? Response and Treatment o What types of medical treatments exist? Describe how these treatments affect the progression of the disease. Describe measures that can be taken to limit the risk of infection.
