Could there be more types of pathogens in the universe?

Would it be possible that other planets, or even other random celestial bodies, contain different types of pathogens? According to Wikipedia, the known types of pathogens are: virus, bacterium, prion, a fungus, algal or eukaryotic organisms. So, is the universe limited to these types of pathogens, or is it possible that somewhere out there, there exist another, or multiple other types of, pathogens? If so, how many types could there be?

If nature fails to deliver, could a hypothetical, very advanced, civilisation create new types of pathogens?

The goal is to affect life on earth, by for example, storing the pathogen inside a comet that is on a collision course with earth. Other suggestions concerning the delivery method are welcome as well.
