3 Project Details Background Information & Student Requirements: Students will research one bacterial pathogen and produce a “Wanted Poster.” Students will then act as the Investigator, solving the crime of WHAT CAUSED IT ….  Determining what bacteria is responsible for their disease

4 List of Possible Pathogens and Diseases PATHOGEN(S) Bacillus anthracis Bordetella pertussis Clostridium botulinum Clostridium perfringens Clostridium tetani Corynebacterium diphtheria Mycobacterium leprae Mycobacterium tuberculosis Neisseria gonorrhoeae Rickettsia richettsii Rickettsia prowazekii Salmonella typhi Treponema pallidum Treponema pertenue Vibrio cholerae Yersinia pestis DISEASE CAUSED Anthrax Whooping Cough Botulism Gas Gangrene Tetanus Diphtheria Leprosy (Hansen’s Disease) Tuberculosis Gonorrhea Rocky Mountain Spotted Fever Typhus Typhoid Fever Syphilis Yaws Cholera Bubonic Plague

5 Project Description Information 1. “Photo" (electron micrograph or microscopic picture/diagram) 2. Description - include Gram stain 3. Organism's m.o. (police jargon) (How the organism attacks and spreads) 4. Most common victims to prey upon 5. Hide out of the culprit (where it is most likely to be found) 6. Most common injury done to victim 7. Is it considered armed and dangerous? rate the degree of damage caused 8. Number of victims (Include if men, women or children) 9. Most effective weapons against the germ 10. Any other identifying characteristics (such as tattoos) 11. How diagnosed, treated, and possible complications, etc.

6 Bordetella pertussis By F ederal D isease I nvestigators This is a stick up … $$$ 100,000 REWARD $$$ Name: Bordetella pertussis Description: the bacterium Bordetella pertussis causes Whooping Cough. B. pertussis is a very small Gram-negative aerobic coccobacillus that appears singly or in pairs. M.O: There are two stages of whooping cough. During the initial stage,an infected person has symptoms characteristic of an upper respiratory infection, including runny nose, sneezing, fever, or a mild occasional cough. It is during the second stage that patients experience a burst of rapid coughs usually accompanied by a characteristic high-pitched "whoop." Common Victims: Young infants and children, but adults can develop the disease Hide Out Spot: Lungs and airways Most Effective Treatment Method(s): Antibiotic therapy Armed and Dangerous…Approach with Extreme Caution!!!

7 Rickettsia richettsii By F ederal D isease I nvestigators I ’ m your worst nightmare $$$ 50,000 REWARD $$$ Name: Rickettsia richettsii Description: Rickettsia richettsii is the cause of Rocky Mountain spotted fever. The Rickettsiae are small, Gram-negative, aerobic, coccobacilli that are obligate intracellular parasites of eukaryotic cells. They may reside in the cytoplasm or within the nucleus of the cell they invade. M.O: Rickettsia rickettsii is found in the Americas and is transmitted to humans through the bite of infected ticks. The bacterium infects human vascular endothelial cells, producing an inflammatory response. Symptoms usually develop 2-14 days after tick bite and can include chills, fever, headache, muscle pain and trademark bulls eye rash. Common Victims: Anyone with access to the outdoors, specifically heavily wooded areas. Hide Out Spot: Anywhere on the skin (Warm snuggly places ) Most Effective Treatment Method(s): Careful removal of the tick from the skin and antibiotics to eliminate infection. Armed and Dangerous…Approach with Extreme Caution!!! Disease Vector Bacteria

8 Streptococcus pneumoniae By F ederal D isease I nvestigators Ready or not, here I come … $$$ 25,000 REWARD $$$ Name: Streptococcus pneumoniae Description: Streptococcus pneumoniae is a normal inhabitant of the human upper respiratory tract. Streptococcus pneumoniae cells are Gram-positive pairs of cocci (diplococci), but they may also occur singly and in short chains. M.O: Symptoms may include fever, chills, headache, ear pain, cough, chest pain, disorientation, shortness of breath and occasionally stiff neck. Common Victims: Although anyone can get pneumococcal disease(s), it is most common among young children, the elderly, or among people with serious underlying medical conditions. Hide Out Spot: Upper respiratory tract, specifically lungs. Most Effective Treatment Method(s): Powerful antibiotic therapy Armed and Dangerous…Approach with Extreme Caution!!!

9 Treponema pallidum By F ederal D isease I nvestigators $$$ 1,000,000 REWARD $$$ Name: Treponema pallidum Description: Treponema pallidum is a spirochete bacterium that causes syphilis. It is not seen on a Gram Stain smear because the organism is too thin. Transmission occurs by sexual contact and from mother to fetus across the placenta. M.O: The primary stage of syphilis is usually marked by the appearance of a single sore (called a chancre), but there may be multiple sores. Skin rash and mucous membrane lesions characterize the secondary stage. This stage typically starts with the development of a rash on one or more areas of the body. The rash usually does not cause itching. Common Victims: Babies (passed during birth from mother), teenagers and adults engaged in risky behavior(s) Hide Out Spot: External genitals, vagina, anus, rectum, lips or even mouth. Most Effective Treatment Method(s): Antibiotic therapy, but reoccurrence is possible Armed and Dangerous…Approach with Extreme Caution!!!
