The Primary and Only Reservoir of Salmonella Typhi Case Study

The man’s wife indicated that he had recently returned from a business trip to
Southeast Asia, and that upon his return he started to run a fever, and
developed a headache, cough and general malaise. His fever rose to
approximately 104 degrees F, and he developed rose colored spots on his
lower chest and abdomen. He began to have diarrhea, 6-8 times per day,
with the stool comparable to pea soup in color and consistency. At this point
the wife insisted that he see a doctor. What is the most likely source of his
illness?  

• identify the disease name (including correct pronunciation), means of transmission and usual
reservoirs  
• etiologic agent (including correct pronunciation of the name of the agent), its
general characteristics and key tests for isolation and identification (be specific
for this microbe!)  
• historical information to include when and who isolated the microbe and any
significance of its name  
• signs and symptoms of the disease; body system(s) usually affected ; how did
you decide that this was the disease?
• microbial virulence mechanisms contributing to the disease process  
• treatment for the disease  
• prevention, particularly current research about a vaccine or other means of
control/prevention  
• minimum five reliable Internet references, plus any other references used.
Sources of photos used in the presentation should be documented in the
reference list.  

When selecting online references, remember that not all information on the WWW is
reliable. Always try to use journal articles or governmental documents as the “authority,”
and not rely on commercial sites (.com) unless the same information appears in multiple
references. Two references with the same URL except for the last part will be
considered the same reference, like different pages in a book. Include all sources used;
reference books and periodicals by a standard format.  
Be VERY careful when referencing online sites. Each underscore, period, or capital
letter must be exact, or we will not be able to find the site. Always check your references
before reporting them by using the OPEN feature on your browser. If your reference will
not open, it will not be counted toward your grade.  
To report your sources, prepare a bibliography on the last slide of your PowerPoint
presentation and number all references used. Then in the body of your report, give the
number of the reference you used for information. This is called end notes, which you
have probably used for other research papers. As with any report, be sure to paraphrase
the information you use. If you choose to use direct quotes from the article, you must
use quotation marks. I will be checking the references, so be sure NOT to plagiarize!!  
There are five required parts of an Internet reference:  
• the author of the article, if available.  
• title of the article  
• the date written/updated  
• Internet address (URL). For example,
http://www2.austin.cc.tx.us/microbio/2704/syllabus.html is the URL or reference
for this page, which should show in your browser heading. An easy way to get
this reference is to copy it from your browser and paste into your word
processing program, so typos will not be made.  
• the date you visited the site.
