so kaplan micro mentions that in kleb pneumonia you get the currant jelly sputum that we all know, but says its not foul smelling, compared to aspiration pneumonia which is foul smelling. Other books including FA say that in kleb pneumo the pneumonia occurs bc of aspiration in debililated patients. so im a little confused here

KLUM. Atypical pneumonias

aspiration pneuomnia will present as foul smelling grrenish/yellowish sputum that will eventually create a lung abscess. However i would not be worried so much about distinguishing between foul smelling and it not being foul smelling. The take home message is that aspiration pneumonia is mainly caused by anaerobic bacteria actinobacter, peptostreptococcus, and so forth. just know gram - anaerobic bugs or strep pnuemo for gram positive. mc tested is anaerobic bugs. And also that itis mc in pts with loss of consciousness so classically alcoholics, epileptics, and etc. Klebsiella MAY cause aspiration pneumonia, BUT it is more common in pts who have poor immune systems/respiratory systems ie diabetics/alcoholics. You will rarely see kleb pneumonia presented for aspiration pneuomia on practice q's. Also why are you doing kaplan for micro, it's a huuuge time sink. FA and uworld is way more than enough then what you need.

not actinobacter, i mean bacteriodes for anaerobic.

As mentioned above, the foul smell in aspiration is due to the action of anaerobic bacteria - they produce short chain fatty acids that have a foul smell. This is a feature of aspiration pneumonia due to the causative organism. Your association that's leading to the confusion is spurious because you're leaving out this link. If one really did have aspiration pneumonia caused solely by Klebsiella, it would not have foul smelling sputum. Fortunately for you though it's extremely unlikely for a patient to develop non-polymicrobial aspiration pneumonia simply because of oral flora.

The real associations therefore are:
Klebsiella - non foul smelling
Anaerobes - foul smelling
Aspiration pneumonia - polymicrobial, including anaerobes

just doing it once over to connect the missing dots FA has, and the videos sort of MAKE me go through micro, otherwise just doing them from FA hyperplasia's my ADD lmao
