I would say CMMRS and FA are enough.
I took notes on CMMRS and combined it with notes from Problem-Based Micro and FA mnemonics. I found it helped quite a bit: all the salient points with any clarifications from textbooks and Wikipedia that you need, in your own words, organized in a way that makes sense to you. If you have the time to do it, make a study guide and study fom that. It'll come much easier. Mine looked something like:
Adenovirus – naked ds linear DNA virus; fever and pharyngitis, with various serotypes also causing conjunctivitis (especially by waterborne route), lower respiratory syndromes (especially by aerosolized droplet route), gastroenteritis (in daycare infants, fecal-oral route; serotypes 40 and 41), and hemorrhagic cystitis. Ad14 is emerging lethal serotype. No Tx.
or
E. coli O157:H7(enterohemorrhagic) – Gram – rods; indole-positive, lactose-positive, sorbitol-nonfermenting, and + for agglutination of O157-specific antibodies. Associated with ground beef and unpasteurized milk. Attach to and efface brush border of intestine by producing phage-encoded Shiga toxins, lethal to colonic (and renal endothelial) cells. Not invasive. Presents as severe cramping followed by bloody diarrhea, but afebrile. Complications include hemolytic uremic syndrome (triad of anemia, thrombocytopenia and acute renal failure), occurring in the very young and very old, due to Shiga toxin binding to endothelial cells in kidney> swelling causing mechanical hemolysis, and endothelial damage consuming platelets . Tx: self-limiting; fluid and electrolyte replacement; abx contraindicated.
And so forth.
Know N. meningitidis and meningococcemia very well for the test. I had 3-4 questions on it.
