text: When Angelo received the report from the CDC, he pored over it for over an hour, analyzing the data and considering their implications. In addition to the information Carlson had summarized by phone, there were over a dozen electron micrographs. These showed pictures of the virus in various feline tissue samples.
  
  "Merda!" The damned thing is a sphere. Aah! Carlson added a size marker. The inside seems to be about 125 nanometers across. Hmmm... typical of many retroviruses. What are these things sticking out? He saw that each viral sphere possessed one or more huge, partially curled filaments measuring about eighty nanometers in diameter and up to a micron in length. Some had as many as six such appendages, each of which appeared to Angelo like a tiny question mark attached to the sphere by its straight section. Angelo realized he'd never seen a virus like this, although the filaments remind him of Ebola virus.
