Case study # 5
November 1,2012

1. What evidence suggests that the young graduate student has contracted what disease? Ans: The signs and symptoms the young graduate student presented, show evidence of Lyme disease.

2. What is the environmental pathway for the vector of this disease? Ans: The environmental pathway for the vector of this disease would be a forested habitat. The black-legged tick or the deer tick is the principle vector of this disease (Lyme disease), and they’re always found in forested habitat like the Pinelands. They actively transmit the pathogen from an infected reservoir host animal to another individual. 3. How did the student come in contact with this organism?

Ans: The student came in contact with this organism during her deer population study and walking miles through the Pinelands; which is a forested habitat and the home to deers.Ticks from these deer usually attaches to the clothes and later travel onto the skin. 4. What is the blood test that would confirm the presence of this pathogen in the student’s blood? Ans: The blood test that would confirm the presence of this pathogen in the student’s blood stream would be an enzyme immunoassay (EIA) or Immonofluorescent assay (IFA) .Specimens yielding positive or equivocal results should be tested further by using a standardized western blot assay. Specimens that are negative by a sensitive EIA or IFA do not need further testing. 5: What are the characteristics of this pathogen.(Morphology,biochemistry,and pathogenicity).How do the possible pathogens in the case study differ? Ans: Borrelia burgdorferi is a spirochete. Spirochetes are a group of phylogenetically-distinct bacteria that have a unique mode of motility by means of axial filaments. (endoflagella).Spirochetes are widespread in viscous environment, they also have a unique cell surface which accompanies their unique type of mortility.The endoflagella are contained within the periplasmic space...
