To determine:
How a microbiologist could determine that the fungal infection in a patient’s lung was ascomycete instead of a basidiomycete. Why aspergillosis is emerging as a new disease. Why a powerful drug like voriconazole is effective against fungi and comparatively harmless to humans.
Case summary:
The patient was not in a good shape. He had nothing to do with his physique or to spend time at the gym but had to do with the ball of
Unfortunately, the disease has not peaked yet for the patient. The fungus Aspergillus invaded his blood and even progressed toward his brain. The symptoms and signs of invasive aspergillosis would be an excessive weakness, extreme tiredness, severe headaches, and delirium which were found to be his daily companion. One side of his body might also be paralyzed.
The patient spent four weeks in the hospital. The brain was being pierced by thin hyphal threads. His personality was almost worsened and he can’t able to get hold of himself. At any time, he would lapse into unconsciousness.
A new antifungal drug (voriconazole) brought the patient back to life. A medical miracle happened with the help of this drug, and the invasive mold was defeated.

To explain:
Why aspergillosis is emerging as a “new” disease.
Case summary:
The patient was not in a good shape. He had nothing to do with his physique or to spend time at the gym but had to do with the ball of fungus that is present in his right lung. Aspergilloma is a fungal sphere that occurred by the single spore of Aspergillus (an ascomycete fungus). The mold had formed by the fungal hyphae mass that invades his lung airways and killing him slowly. This kind of bronchopulmonary aspergillosis is a rare but frequently increasing pathogen in immunocompromised people. Apart from difficulty in fever, chest pain, and breathing, the patient hated the most was coughing up of bloody mucus. He coughed up his lung pieces out.

Question: In a tabular form, compare and contrast cyst from trophozoite stages of the protozoa.arrow_forwardTJ Porter was a 15 year old high school student with a new summer job working with a gardening crew. His main job activity was spreading bark mulch in garden beds. Last August he rapidly developed severe shortness of breath, a persistent cough, and chest pains. On admittance to the hospital, radiological examination revealed large “cotton ball” densities in both of his lungs. Culture of his lung aspirate grew Aspergillus fumigatus. TJ was given IV amphotericin B and assisted mechanical ventilation via a tracheotomy. He slowly improved in the hospital, but also contracted 2 other respiratory infections with Pseudomonas aeruginosa and Strep. faecalis. These infections were treated with appropriate antibiotics.TJ had 4 sisters and 2 brothers. One of his brothers had a perirectal abscess in infancy but otherwise has been well.TJ’s white blood cell count was in the normal range, with ~65% neutrophils, 30% lymphocytes, and ~5% monocytes. Serum IgG and IgM levels were in the normal-to-high…arrow_forward

Question: In a tabular form, compare and contrast cyst from trophozoite stages of the protozoa.arrow_forwardA 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.
