Infx Dz on path miniboard?

Has anyone who has taken the path miniboard recall how much micro is on it? Robbins has devoted a whole friggin chapter to infx dz, where as we didn't even cover it in path (as I suspect most schools don't, given that it's usually all covered in micro). Do I really need to spend any time re-learning micro right now? I would understand having some stuff that relates to path (infx endocarditis, pneumonia, osteomyelitis, HIV, etc), but some of this stuff is straight virology and bacteriology.
