Microbial DNA isolation from WBC with Chelex 100?

[Mikhail]

I am looking for a method of microbial DNA extraction from white cell
fraction of blood using the Chelex 100 resine.
I am particularly interested in isolation of C.pneumoniae DNA with
Chelex 100 for subsequent detection by PCR. However, I would appreciate
any reply from those who use Chelex for processing PCR blood samples.

Sincerely,

Michael Edelstein.
