The famous mnemonic in every book

Some Killers Have Pretty Nice Capsules

Streptococcus pneumoniae
Klebsiella pneumoniae
Haemophilus inlflenzae
Pseudomonas aeroginosa
Neisseria meningitidis
Cryptococcus neoformans

But also worth remembering

  • Bacillus anthracis as it has a sepcial poly D glutamte capsule unlike all others which is polysaccharide capsule
  • Neisseria meningitis type B and Steptococcus pyogenes have non-immunogenic capsules therefor no vaccine
  • Neisseria gonorrhoeae has no capsule and therefore no vaccine
  • Bordetella pertussis has a capsule also
  • All capsular agents will show a positive Quellung reaction
