Cool cAMP inducers Mnemonic

Mnemonic for cAMP inducers (in bacteriology):
C- Cholera (Vibrio) causing rice water diarrhea
A- Anthrax (Bacillus Anthrax),its edema factor is an adenylate cyclase.
M- eNterotoxigenic Ecoli causing watery diarrhea
P- Pertussis causing whooping cough and lymphocytosis.

Another one for ADP ribosylating A-B toxins (most of which are also cAMP inducers)...

ABCDE

Anthrax
Bordetella pertussis
Cholera
Diphtheria
E. coli

All of them are also cAMP inducers except for diphtheria... and you should know that that one targets EF-2.

I imagine that they induce cAMP by ribosylating ADP, thereby decreasing the ADP substrate supply for cAMP. I don't know if that's right, but it's how I remember it.

This works for me...

C- Cholera (Vibrio) causing rice water diarrhea
A- Anthrax (Bacillus Anthrax),its edema factor is an adenylate cyclase.
M- Moctezuma revenge (traveler's diarrhea) Enterotoxigenic E coli causing watery diarrhea
P- Pertussis causing whooping cough and lymphocytosis

Default Camp pye

I would also add Yersinia and Pseudomona

C-Cholera, Vibrio
A-Anthracis, Bacillus
M-
P-Pertussis, Bordetella

P-Pseudomona aeruginosa
Y-Yersinia Pestis
E-E.coli Enterotoxigenic Heat Labile Toxin

ADP Ribosylatin A-B toxins just means that pentose sugar + ADP are added to some protein, transcription factor, secondary messenger and provoque and undesire respone. Bordetella, E.coli and vibrio cholera do this. E.coli LT and cholera CT do this by stimulating Gs protein, Pertussis does this by Inhibiting Gi protein

ABCDE mnemonic works well but you have to add B.cereus, C.botulinum, Pseudomona Exo S as they ribosylate small GTP binding proteins

Adenylate cyclase toxins are toxins that enter intracellularly and are activated by some messenger protein (calmodulin) and induce a CAMP increase.

Only four have adenylate cyclase toxin ability, Bordetella, Yersinia, Pseudomona Exo Y and Bacillus Anthracis.
