BIOS 242 Week 6 Discussion 2 – Make the Diagnosis Bacteria
Question
The assigned readings encompass a wide variety of diseases associated with various
... [Show More] organ systems. Using the information in your text (and any other resources you choose), give your patient one of these diseases from the organ system discussed this week, and present the history and symptoms to the class. Be creative! Be sure to offer enough information to make an educated guess, but try not to give it away too soon! Each student should present a case. Be sure to let those who respond to your case know whether they correctly diagnosed the patient. In some cases, you might offer new test results midweek if the class is stumped!
ANSWER
Hepatitis A is a viral liver disease that can cause mild to severe illness. The hepatitis A is transmitted through person to person, either by contaminated food or water. It is typically contacted through ingestion of the contaminated substance. The virus can be explosive and cause substantial economic loss. It will spread quickly, in an unsafe and untreated water and food sources. If you have this infection, you have inflammation in your liver that's caused by a virus. You don't always get symptoms, but when you do, you might have, Jaundice (yellow eyes and skin, dark urine), pain in your belly, loss of appetite, nausea, fever, diarrhea, and fatigue. You can spread the hepatitis A virus about 2 weeks before your symptoms appear and during the first week they show up, or even if you don't have any. It is normally diagnosed with a simple blood test. If you happen to contract the virus, it usually recovers fully, with lifelong immunity. However, Hep. A can be deadly if left untreated.

Q.)
Your 8-year-old child has missed several days of school due to repeated bouts of strep throat. She is sick again and you took her to the doctor, concerned that she is dehydrated because of low urine output. The doctor found that her blood pressure was high and a urine test revealed blood in her urine.
What is the most likely diagnosis for her symptoms? What has caused this condition to develop?
A.)
I believe that she might have Mononucleosis or mono or “the kissing disease”. With the diagnosis of strep and it being recurrent, also it not getting better, I feel that could be the under laying cause. Mono is caused by sharing drinks and/or sneezing in a person’s face. Mono is contagious like a common cold and can be spread as such. With Mono, you can get high fevers, recurrent strep, and dehydration; Which could cause high blood pressures and low urine output. The blood in her urine, could be caused from her kidneys over working to beat the infection. I would order a blood test to confirm and culture her urine to make sure nothing else grows. I would have an IV started for the dehydration and monitor her BP, while we wait for the results.

Q.)
Compare and contrast Rickettsia rickettsii and Chlamydia trachomatis with respect to structure, disease transmission, and pathogenesis.
A.).
Chlamydia and Rickettsia are 2 groups of Gram-negative bacteria
Both bacteria are
-obligate intracellular parasites
*they must steal host ATP to live
-Chlamydia cannot make any ATP whatsoever
-Rickettsia can make some (but not enough)
*they cannot be cultured on non-living artificial media
-instead, they are inoculated into living cells for culture.
-about the size of large viruses (i.e. quite small)
*however, they arenaviruses because they
-have both DNA and RNA
-viruses have only one or the other
*synthesize their own proteins
*Chlamydial transmission is Person-to-person while Ricettsia transmitted through arthropod vector. [Show Less]
