>bacteria: Staphylococcus aureus is the best, but P. aeruginosa is very beautiful and "voluptuous". Rickettsia are cute. Clostridium tetani is a chad
>viruses: Flaviviridae, Retroviridae and Bunyavirales are really good. HCV is my favourite though
>fungi: Cryptococcus neoformans, Aspergillus Flavus. C. immitis is good even if I don't like dimorphism.
>protists: Naegleria Fowleri, Toxoplasma gondii. Leishmania donovani would be really nice but she is an asshole and kills dogs.
>worms: I don't respect them at all. all disgusting. Onchocerca volvulus and Dracunculus are funny at least

Overall favourite: all Aspergillus. Otitis, keratitis, pneumonia, encephalitis. these moldy chads got the whole package and are ready to make the local immunocompromised cuck seethe. Cherry on the cake: their toxins, all of them.
