My assignment for Module 1 SLP was to read the background information on; A Multistate Outbreak of E. coli 0157:H7 and answer the following questions: 1. What could account for the increase in cases? 2. Compare the DNA fingerprints in Figure 2 from seven of the E. coli O157:H7 cases. Each isolate has its own vertical lane (i.e., column). Controls appear in lanes #1, 5, and 10. Which isolates appear similar? In your opinion was DNA typing necessary in this case? Why?

The reading also discussed the first outbreak in the United States in 1982 when someone who ate some contaminated meat had a bloody stool and when tested is was detected as E. coli O157:H7. What could account for the increase in cases? It is my opinion that cases of E. coli O157:H7 the increase in the outbreak was a result of inadequate diagnostic and limited resources. The symptoms even though common aren’t routinely checked by healthcare providers which may allow the bacteria to spread to another person of the person isn’t aware that they are infected. The bacteria may also spread from one contaminated meats from the farm to the grocery store and then consumed by the consumer. Travelers or tourists from other countries who have consumed contaminated meats who enter the US may spread the bacteria because they may have had the symptoms but were unaware. The outbreak cases in June and July of 1997 may have been from the increase of hamburger meat consumption during the summer months because of under cook meats on barbeque grills and improper meat temperature storage. The prevention of spreading the bacteria: * After contact with cattle or their manure (feces)
