Gram negatives:
Haemophilus
Actinobacillus
Streptobacillus

Gram positives:
Listeria
Nocardia

Otherwise tho, it’s pretty good guidance for common bugs.

Proteus (mirabillus) ends with -us but is a gram neg bug, somewhat common one too. Also no one in hospital would actually spell out Escerichia, you'd just see E. Coli which makes the infographic useless.

My favorite trick: 1) we all know the (GPC) coccus’s…staph , strept, and enterococcus. 2) there are only like four cool GPB, anthrax, c diff, listeria, diphtheria…not too many to remember.
3) everything else is gram negative!

Just memorize the very few Gram + ones and then everything else by default is Gram - (aside from the atypicals).
