The organisms are as follows:

  • Neisseria sicca – the only gram-negative coccus considered inBacteriology 102.
  • Pseudomonas fluorescens – a non-fermentative rod.
  • Three enteric-like organisms: Vibrio cholerae, Photobacterium phosphoreum and Plesiomonas shigelloides.
  • Three relatively obscure enterics: our new organism (shown by initials"AH" as I am not inclined toward saying much about it until it is published),  Budvicia aquatica and Edwardsiella tarda.
  • Escherichia coli – the archetypal enteric – with twoclosely-related species, Shigella dysenteriae and Escherichiahermannii.
