clinical microbiology ridiculously simple Errata?

[hmm...]

My microbio prof just said not to study first aid 08 or microbio made rid simple with our course because of serious errors that we would not recognize as wrong. They are good just for review. I would like to use the books I have already bought. I know there is an official and also unofficial errata for First Aid, but is there one for the MicroBio made ridiculous simple?

I used MMRS along with our micro course and I didn't run across any "serious errors." There were a few minor flubs but nothing that would've screwed with my ability to understand the big concepts (or miss any questions on the exams).

I would use the course notes as the primary study source. If you know those real well, then any aberration in MMRS should be very obvious.

Bumping this since I think I noticed one on page 75 under Klebsiella pneumoniae it mentions that it's encapsulated but then calls the capsule antigen O antigen when only a few pages before it explains that O antigen is the O antigen of LPS and K antigen is the capsule antigen...pretty sure this is a typo. Obviously it has O antigen but that's because it has LPS.

Of course I'm not really sure then whether the O antigen is why the jelly is red or if that's the K antigen. Doubt this is going to come up on boards (whether it's red because of O or K), but I'm kinda curious lol. I think maybe they just phrased it weird and meant the K antigen since it's the capsule around the O antigen?

I think its red because it is blood and inflammatory cells along with the very thick mucoid capsule of klebsiella. I am not using MMRS so i cant help ya there

I thought the red would be from the blood and lung tissue breakdown as well but MMRS says it's the capsule itself that makes it the currant jelly. I think they meant K antigen when they wrote O antigen capsule.

Oh here's another one, on page 94 for Gardnerella vaginalis it explains clue cells as vaginal epithelial cells with "baceteria within the cytoplasm". Pretty sure this should be epithelial cells with fuzzy borders because they're covered with bacteria-they're not necessarily in the cytoplasm, and more importantly you would identify them by the fuzzy borders from being covered in bacteria. No other source I could find seems to mention them actually going inside, although this might be true.

I think most of the errata are just silly little things that won't really matter, plus first aid got this one right anyway.

One error that was pointed out that isn't just in CMMRS or First aid is the fact that everyone believes Listeria Monocytogenes produces endotoxin. You can find this error in even some of the big microbio text books, its insane.

The truth is that no G+ bacteria make endotoxin components. This error stems from a study done in 1979. No one has been able to reproduce the results and it was refuted by another study in 1986.

I am not sure what we are expected to know about this for the boards, so if anyone can chime in, I would appreciate this.
