In the context of the great diversity of oral microflora, including over 600 species, we highlight the educational value of electron micrographs and images of dental plaque cultures in dental models made with culture media, showing the bacterial colonies in the anatomic sites of the teeth that were most abundantly colonized. Such images allow for an easy understanding of the magnitude of the or...

The detection of infective endocarditis (IE) of oral origin has been previously discussed. However, there are few reports confirming this infection using molecular biological techniques. We herein describe the case of a 67-year-old man who developed IE. Blood culture samples and strains obtained from the gingival and buccal mucosa showed 100% identity to Enterococcus faecalis JCM 5803 on sequen...
