Viral proteases are an important target of antivirals. Which of the following viruses make a single polyprotein that is post-translationally cleaved by proteases, into separate proteins?

A group of cigar smoking men aged 60 – 85 yo, met for a conference in a cold city in the winter. Soon after their conference, they all became ill with pneumonia, which was determined to be caused by Legionella pneumophila. What was the source of their infection?

A 25 yo man arrives at the UF Health ED where he is unresponsive to moderate shaking. He was at a party where he was consuming alcohol and recreational drugs. Breathing room air, ABG data are as follows; pH = 7.14, PaCO2 = 78 mm Hg, PaO2 = 50 mm Hg, HCO3- = 26 mEq/L, and SpO2 = 86%. From these clinical data, you conclude that the A/a gradient of this patient is

A 21 yo male college student has been studying hard for exams and has become rundown. He develops a severe sore throat followed by a hacking, dry cough. The cough is so severe that he is having trouble studying. He denies myalgias (muscle aches). On exam, he has a fever of 38.5°C, a respiratory rate of 16 (within normal limits), and on lung exam you note fine inspiratory rales in both lower lobes. His CXR reveals bilateral patchy infiltrates in a bronchopneumonia pattern. What is the most likely organism to be causing his pneumonia?
