Pathogenic clostridium species (non difficile): what causes an increase?

[helen1]

I'm a little distressed - okay freaked out - by my latest organic acids results showing a dramatic increase in 'other pathogenic clostridium species' , as in 'other' than c. diff. which were low. The marker for this, HPHPA, went from 132 a year ago, to 785 now. I can't find any information on what would cause such an increase. The reference range is under 208.

Any brainstorming ideas or actual info would be great. Thanks.
