Protozoa and periodontal disease

[John Bohmfalk]

In my parasit class, we just talked about both T. tenax and E.
gingivalis.  Since both organisms feed on bacteria, my students were
wondering whether people infected with either or both organisms might have
a reduced incidence of periodontal disease.  I haven't been able to find
any references in this regard.  Do any of you have any information, ideas,
suggestions or references?

Thanks.
