Yes. Aspiration pneumonia is any pneumonia caused by aspirating fluids or solids. Anaerobic pneumonia is pneumonia caused by an infection of anaerobic bacteria.
I do not know of any anaerobic pneumonia that is not brought on by aspirating something, but there definitely are aspiration pneumonias that aren’t anaerobic pneumonias, such as the vomit example I gave in my above comment.
Is there a difference between aspiration pneumonia and anerobic pneumonia?
