Textbook Question
Chapter 12, Problem 1EDCS
Matt spent four weeks in the hospital. The worst days were those when he was aware. The sheer terror of knowing his brain was being pierced by thin hyphal threads, digesting his personality away, was almost more than Matt could stand. He looked forward to the times he would lapse into unconsciousness, even though he knew that each period of wakefulness might be his last.
A medical miracle in the form of a new antifungal drug (voriconazole) brought Matt back to life. The invasive mold was defeated, and Matt returned home grateful, aware that life is precious and hopeful that no more spores floated his way.
- 1. How could a microbiologist determine that the
fungus in Matt’s lung was an ascomycete rather than a basidiomycete? - 2. Why is aspergillosis emerging as a “new” disease?
- 3. Why is a powerful drug like voriconazole effective against fungi but relatively harmless to humans?

Some strains of Staphylococcus aureus produce exfoliative toxin, a chemical that causes portions of the entire outer layer of the skin to be sloughed off in a disease called scalded skin syndrome.Given that cells of the outer layer are going to fall off anyway, why is thisdisease dangerous?
In 2001, endospores of Bacillus anthracis, the causative agent of anthrax, were sent to government officials and news agencies via the mail. In response, the US postal service began to irradiate mail with UV light. Was this an effective strategy? Why or why not? Explain

- Bacillus anthracis (Anthrax) Shape and arrangement of your pathogen Bacillus shape and Streptobacilli arrangement Type of flagella, number and correctly named arrangement of the flagella (example: monotrichous) My pathogen is one of the few in its specie that is not motile. It contains one flagellin gene, however four essential proteins contain point mutations and frameshifts. Therefore, the flagella are nonfunctional and the organism lacks motility; Atrichous. Capsule or not (If yes, describe what is it made from) Yes. It is made of poli-y-D-glutamic acid (PGA).

- A 9 year old boy with cystic fibrosis – a genetic disease that causes a number of problems, including the build-up of thick sticky mucus in the lungs- complained of increasing fatigue, shortness of breath and worsening cough. When his mother took him to the doctor, she mentioned that his cough was a blue green color. His doctor immediately suspected a lung infection by Pseudomonas aeruginosa a common complication of cystic fibrosis. A sputum was collected and sent to the clinical laboratory. In the Clinical laboratory, the sample was plated onto Mac Conkey agar and blood gar and incubated. Mucoid colonies surrounded by bluish green color grew on both types of agar media. The colonies on Mac Conkey had no pink coloration, so the medical technologist concluded that the cells did not ferment lactose. She noted that the blue green color on the agar plates and in the sputum, knowing that P.aeruginosa makes several pigmented compounds that give rise to colors ranging from yellow to blue.

- Alexander Fleming was working with bacteria called staphylococcus, which looked like bunches of grapes under the microscope. He could grow colonies of these bacteria on petri dishes with a growth medium. When he returned from vacation, he found that several of these dishes had become contaminated with a fungus. The colonies near where the fungus was growing had been destroyed. Fleming then grew the mold and purposefully added it to a petri dish that contained bacteria colonies. The colonies exposed to the mold died. Fleming named the substance within the mold that killed bacteria "penicillin." REASONING: If mold contains a substance that kills bacteria, then ... a) bacteria exposed to mold would be destroyed b) bacteria could be grown on a growth medium c) fungus can be grown as easily as bacteriaarrow_forwardOnce these pathogens enter the host the difference in environmental conditions signals for them to germinate and turn into growing cells.

- In 1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture dishes. He noticed that a mold called Penicillium was also growing in some of the dishes. A clear area existed around the mold because all the bacteria that had grown in this area had died. In the culture dishes without the mold, no clear areas were present. Fleming hypothesized that the mold must be producing a chemical that killed the bacteria. He decided to isolate this substance and test it to see if it would kill bacteria. Fleming transferred the mold to a nutrient broth solution. This solution contained all the materials the mold needed to grow. After the mold grew, he removed it from the nutrient broth. Fleming then added the nutrient broth in which the mold had grown to a culture of bacteria. He observed that the bacteria died which was later used to develop antibiotics used to treat a variety of diseases. (Biology Corner) 1. What was the initial observation Fleming made? 2.
