Case Study: Legionella by JESSICA LASKE https://padlet.com/laskej/tri31a1iel5rjc5i en-us 2023-09-06 02:18:03 UTC 2023-10-13 12:13:21 UTC hello@padlet.com 1. Patients signs and symptoms laskej https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685857597 -Severe pneumonia for 4 days
-Is currently being treated for multiple myeloma (immune system impaired=more susceptible for illness/virus).
-Found to have respiratory, renal and bone marrow failure.

(Information collected from case study slides)

These signs and symptoms are accurate to the Virus Legionellosis. These signs and symptoms include:
  • high temperature, feverishness and chills;
  • cough.
  • muscle pains.
  • headache
  • pneumonia, very occasionally.
  • diarrhea and signs of mental confusion.

The microbiology tests that were ordered, explained. laskej https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685858471 Due to the patients symptoms, lab techs were able to do the proper tests with the proper technique in order to confirm that the bacteria that invaded their patient was in fact legionella! These tests included: 
-3 days of moderate incubation, a fastidious bacterium grew.

-L-cysteine is necessary for development (auxotroph) only when grown on certain media (Buffered Charcoal Yeast Extract, or BCYE).

-The colony shape was observed under a dissecting scope to be opal-like with a speckled blue-green or pinkish-white tint.

The treatments that were prescribed. laskej https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685860366 The treatment was prescribed by patients doctor of Levofloxacin, a fluoroquinolone antimicrobial agent. So that this can stop the DNA synthesis of this particular bacteria and eventually cure the patient. The fluoroquinolone antimicrobial agents usually fight off gram-negative bacteria, so once the laboratory results came back that this was Legionella, a gram-negative bacteria, she was put on levofloxacin right away.

-Patient recovered. 

-The clinician could not have diagnosed this patient’s illness without the assistance of the clinical microbiologist.

When looking at Legionella under a microscope one would find it to look like this: laskej https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685861325 Here we see Legionella under a microscope, the staining technique that was used here was a gram stain using safranin to stain the gram negative stain pink. ]]> 2023-09-06 02:21:04 UTC https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685861325 2. The typical shape and arrangement of legionella. laskej https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685862201 This is what the arrangement of legionella looks like! This bacteria is a rod shaped.]]> 2023-09-06 02:21:34 UTC https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685862201 4. Unique features that may be seen with light microscopy of the bacilli: laskej https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685862854 Legionella cells are small, Gram-negative bacilli that range in size from 2 to 20 m. After growing on the surface of agar, specifically, long, filamentous forms may arise. Typically this growth happens within three days of incubation.

Staining techniques that were used to characterize the bacterium in this case study. laskej https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2685863581 The Legionella bacterium is a tiny, gram-negative, waterborne, aerobic, nonmotile, and oxidase and catalase positive bacillus. The finicky Legionella bacterium won't grow anaerobically on a common media. the staining technique that you would want to use would be, Colony Gram stain: pleomorphic Gram-negative rods.

How did the health care team use the test results to make a diagnosis? laskej https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2691681634 Legionellosis can be clinically suspected, but only laboratory testing can confirm the diagnosis. Culturing on special charcoal-containing agar is the favored technique. It also can be identified as legionellosis because growth time during incubation period is 3-14 days and this happened to grow within three days. The growth also presented an Opalescent, speckled blue-green color and was able to grow only in the presence of L-cysteine in the media.

I thoroughly enjoyed doing this case study because it really did just prove how I love researching different types of bacteria and viruses and how they spread as well as how to stop the spread, because as a nurse it is very important to know how to prevent or stop the spread of bacteria and viruses so we can keep our patients happy and healthy!]]> 2023-09-09 15:51:33 UTC https://padlet.com/laskej/tri31a1iel5rjc5i/wish/2691704864
