What is the gram stain for the west nile virus?

Answer 1

There is no Gram stain for the rabies virus - it does not pick up either the stain or the counter-stain and has no official Gram stain status like bacteria do. When scientists are looking at slides of brains to see if an animal was infected with rabies, they use a special immunofluorescent stain made of antibodies against the rabies virus linked to either a vividly colored pigment or a fluorescent pigment. If the rabies virus is present, the antibodies in the stain adhere to the viral particles and then the pigment becomes fixed to the tissue as well, allowing the pathologist to "see" the virus (actually just that the virus is present and approximately where it is at - the virus is too small to see with a standard light microscope).
