MICROBIOLOGY PRSENTATION Topic: streptococcus pneumonia Presentation title: you should think of a creative title for your presentation
Format: PowerPoint presentation Visual Aids: tables, figures, diagrams, graphs, photos, maps, etc… (you should have a good balance of word & figures throughout the presentation) – if you would like to use a figure from the textbook email me, and I will provide it for you. You must request the image no later than 2 days before your presentation What you will cover: 1. Pathogen / type of microbe a. Is your pathogen a virus or bacterium? b. Scientific name of the pathogen i. For a virus give the family of viruses your specific virus belongs to ii. For a bacteria give the genus and species name c. For bacteria: i. Is it Gram-positive or Gram-negative? ii. What is the morphology? iii. What are the oxygen requirements (aerobic, anaerobic, etc…) iiii. Does your bacterium have any special structural features? (capsule, flagella, endospore, etc…) v. What type of cell or tissue does it infect/colonize? d. For viruses: i. What type of genome does it have? (DNA or RNA) ii. Is it enveloped or naked? iii. Does it have any proteins associated with the virion? iiii. What type of cell does the virus infect? v. What are the host cell receptors? 2. Diseases – list any disease(s) your pathogen causes 3. Epidemiology – (do not spend a lot of time on this portion of the talk) a. What regions locations is pathogen typically found? (widespread or only found in a certain area?) b. What is the mortality rate? With or without treatment? c. Is there a particular population that is more susceptible to the pathogen? 4. Transmission a. How is the disease transmitted? b. Are there multiple modes of transmission? c. What is the common reservoir for the pathogen? d. Is transmission seasonal? 5. Symptoms a. What are the major symptoms associated with the primary disease caused by the pathogen? b. Explain any medical terms c. Are any symptoms unique to the pathogen or disease? d. Does the pathogen cause a chronic or acute illness? e. What is the incubation period? (how long before symptoms show up) 6. Diagnosis a. Are any clinical symptoms diagnostic for the pathogen/disease? b. How is the disease/infection commonly diagnosed? c. Are there any special lab tests? If so, what do they detect? DNA, protein, etc..? 7. Treatment & Prevention a. What common drugs or therapies are used to treat the disease/infection? b. Is drug resistance common in your pathogen? c. Are there any actions or drugs that can be used to prevent infection or spread? 8. Major virulence factor(s) - does your pathogen have any specific proteins, structures, features, or mechanisms that it uses to cause disease? If so, state them and give a brief explanation, as time allows. 9. References – list all references used to gather information. You do not need to present the references. Just list them on the last slide of your presentation. Information sources: Your textbook will serve as your primary reference. However, you will most likely need additional references to gather all of the required information. A couple of acceptable sources are listed below: Centers for Disease Control and Prevention: https://www.cdc.gov/ World Health Organization: http://www.who.int/en/ MicrobeWiki: https://microbewiki.kenyon.edu/index.php/MicrobeWiki WIKIPEDIA IS NOT AN ACCEPTABLE SOURCE!!!! You may use a source other than the two listed above if it is another textbook or a reputable scientific website. You can ask me if you are unsure!
Additional Considerations: • The font used in your presentation should be block print. No cursive or script fonts.

Explanation / Answer

1. a. bacteria

b. Streptococcus pneumonia, Genus- Streptococcus , Species-pneumoniae

Gram positive, cocci in shape, facultative anaerobes.

Special polysaccharide capsule.

Common sites of infections- bloodstream, lung tissue,meninges of brain, middle ear in children.

Uncommon sites- Skin and soft tissues .

2. Pneumonia, meningitis , middle ear infection in children.

3. Epidemiology- most prevalant in children under 2 years , and adukts above the age of 65 years.

  Locations- high crowded areas such as prison, military camps,homeless shelters.

Mortality rate - 5-35% depending on the age , race , geographical area.

4. Mode of transmisson - direct person to person contact and through saliva and mucus.

Reserviour - nasopharynx of asymptomatic person, no animal or insect reserviour.

Infection increases during the winter.

5.Symptoms -fever, cough, shortness of breath, chest pain, stiff neck, confusion and disorientation, sensitivity to light, joint pain, chills, ear pain, sleeplessness, and irritability.

Both acute and chronic infections are possible.

Incubation period- from 1 to 3 days.

diagnosed from sputum sampling and blood tests, meningial infection is detected by lumbar puncture.

7. Treat ment with broad spectrum antibiotics .

Prevention- vacines are avialable for strep. nowadays

8. Virulene Factors-

Polysaccharide capsule- saves it from the phagocytes.

pneumolysin- actual toxin which inhibits antibody synthesis and lymphocyte proliferation.

Apologies, i cant make ppt here, hope this helps.
