Becca Harris Writing 101 Position Paper Eliminating Genetically Modified Food at PLU What comes to mind when reading the words genetic modification or Bacillus thurigiensis (abbreviated Bt)? I envision laboratories and science experiments‚ when in reality these words are related to the food we eat every day. What most Americans do not know is the threat that genetically modified food presents to our communities. PLU should do everything in its power to ensure that its students and faculty

Ch. 2: Fundamentals of Epidemiology Causality: determining the cause of a disease Screening test: test given to people who have no symptoms to check for the presence of a particular disease Natural History of Disease: the course of disease if left untreated Latency period: time from start of disease process until signs/symptoms appear (Incubation period: time b/w infection & clinical disease) Nonclinical stage: no signs/symptoms present – pathologic changes occur Preclinical – sings/symptoms

Clostridium difficile There are many microbes that live in the human digestive tract. Most keep us regular and healthy. Some of these organisms keep others in check. When the balance of these good and bad organisms is disrupted‚ we can become sick. Clostridium difficile (C.diff or C.difficile) can grow out of control if this happens. This happens when a person is on antibiotics for another reason and the normal flora of the gut is eradicated. Clostridium difficile is typically found in hospitals
