GUILARTE, C.  and  PERRONE, M.. Detección  de especies de bacilos anaerobios gram negativos en pacientes con periodontitis crónica.. Acta odontol. venez [online]. 2007, vol.45, n.1, pp.06-13. ISSN 0001-6365.

The objective of this study was to determine the presence of Gram Negative rods anaerobic species in patients with chronic periodontitis. The periodontal pocket samples the patients with periodontitis were taken by means of paper cones and transported in pre-reduced Thioglycolate Broth and them were streaked on blood agar Schaedler base in order isolate anaerobic bacteria. The identification was carried out by RAPID ID 32A enzymatic system. Prevotella intermedia (36,66%), Prevotella melaninogenica (6,66%), Prevotella loescheii (16,66%), Porphyromonas gingivalis (30,99%), Fusobacterium nucleatum (3,33%) y Bacteriodes sp. (3,33%) were the species identificated in this studied.
