[PD] dsp lowest frequency?

Hi all!

Maybe it's a stupid question but I was reading this 
http://www.dspdimension.com/PDF/DftAPied.pdf and it confused me a bit. 
Theoretically, if we have a sample rate at 1000Hz, the highest possible 
pitch will be 500Hz. But is there an opposite limit? Is there a "lowest 
possible pitch" for different sample rates? Is DC always there no matter 
what SR is or the lowest frequency boundary is moving also?
