Gram positive bacteria have a thicker layer of peptidoglycan outside the cell membrane than gram negative bacteria. GN: Salmonella, GP: Listeria moncytogenes

1. Name three ways in which a cohort study differs from a case-control study.
2. Give two examples of artificially acquired active immunity that don't include a vaccine.
3. What are nutritional causes for a disease?
4. What is a choropleth?
5. What is the ATSDR?
6. Which bacteria can be transmitted by contaminated poultry, milk and other dairy products or salad greens? It's often spread due to poor sanitary practices.
7. What is the difference between the mortality rate and the morbidity rate?

1. Cohort studies are enrolled based on exposure status, while case-control studies are enrolled based on disease status. Cohort studies can be either prospective or retrospective, while case-control studies are only retrospective. Cohort studies test well for rare exposures, while case-control studies test well for rare diseases.
2. Toxoids and Immunoglobin? Wasn't too sure about this one.
3. Nutritional causes for a disease are excesses or deficiencies in the body that cause illness. Vitamin deficiency, high iron, etc.
4. A map which is shaded to show the density of a disease geographically.
5. Agency for Toxic Substances and Disease Registry
6. Campylobacter jejuni
7. Morbidity Rate is the rate at which a disease is present in a population, while mortality rate is the rate of death in a population.

1. Correct!
2. I asked a really bad question...sorry I'm just going to not count this one. :oops:
3. Correct!
4. Correct!
5. Correct!
6. I was looking for Shingella, althoughy campylobacter jejuni has really similar modes of transmission.
7. Correct!
Your turn!

Neonatal Mortality Rate: ratio that expresses the number of deaths among children from birth up to 28 days of age(exclusive) divided by the number of live births during a given time period, generally per 1,000 live births
Post-neonatal Mortality Rate: ratio that expresses the number of deaths among children from 28 days of age to 1 year(exclusive) divided by the number of live births during a given time period, generally per 1,000 live births
Infant Mortality Rate: ratio that expresses the number of deaths among children under 1 year of age reported during a given time period divided by the number of live births in the same time period, generally per 1,000 live births

I'll post a few questions, I hope Knyte_Xjn doesn't mind.

1. What is a serotype? Give two examples.
2. Describe the natural history of disease timeline.
