I was only in school for one day this week. In that day we discussed the things in the pond. I shared that the small crustations everyone saw were water fleas. There was also alge in the water that we could see. Nothing we could see was visable. Almost all bacterias and viruses are not visible under a microscope. We said there could still be bacteria in the water.
Next we came up with four possible bacteria for the chicken. Salmonella, staphylococcus aureus, campylobacter, and listeria monocytogenes are all found with chicken.
-Staphylococcus causes pimmples, boils, and impatego. It also causes more life threatening viruses like meningitis and pneumonia. None of these diseases relate to the symptoms the infected people described.
-Salmonella is found in eggs. It is one of the most common foodborn diseases. People expirience fever, diarrhea, abdomanal cramps, chills, nausea, and vomiting. Salmonella has all of the symptoms the middle schoolers had. This is the website I found to learn about salmonella. http://www.fsis.usda.gov/factsheets/salmonella_questions_&_answers/index.asp
-Campylobacter is one of the main cause of bacterial foodborn diseases. It causes tissue damage in the colon. None of the people absent had colon damage.
-Listeria Monocytogenes causes muscle aches, fever, and sometimes nausea and diarrhea. It can cause Menintgitis. It doesn't match at all. The disease only appears in newborns, old people, and pregnant women.
Salmonella is the one the fits the discription most. The chicken could have had a lot on it and the kids ate it.
