For those studying at home, this is what an asthmatic airway looks like under the microscope. Trust me, it is yikers. That middle lumen should be clear, but it is filled with mucus which is being produced by too many goblet cells in the epithelium. #HistoPath

This slide is a highly magnified sample of brainstem from a rabid bobcat. Ihas a single neuron with branched axon at one end and a large nucleus with a prominent nucleolus at the other end. The cytoplasm has been stained brown by an immunohistochemistry stain specific for the rabies virus. Another process extends from a point adjacent to the bifurcated axon. The unstained nucleolus and the processes give the distinct appearance of a fish.

A new kind of box #fish? Nope! It's much more interesting. This fishy cell has been stained with an antibody specific for rabies. They don't call it neurotropic for nothing! Antigen fills the cytoplasm but spares the nucleus creating a stark contrast betw the two.🧪

Lovely uremic pneumonitis lesions in a dog.

(Lovely for me, not for the dog)
