“…Los microorganismos más frecuentemente aislados de la bolsa periodontal han sido muy estudiados en Norte América (7,11,(14)(15)(16)(17)(18)(19) y Europa (20)(21)(22)(23). Sin embargo, el perfil microbiológico de la periodontitis en poblaciones de Asia (24)(25)(26)(27), África (12,(28)(29)(30), Centro (31) y Sur América (32-37) parece diferir en frecuencia y composición debido, en parte, al frecuente hallazgo de microflora no usual. Por ejemplo, los bacilos entéricos de las familias Enterobacteriaceae y Pseudomonadaceae producen factores de virulencia que podrían afectar el comportamiento clínico de la periodontitis, así como su control y tratamiento.…”

Introducción. Los microorganismos involucrados en la periodontitis varían en cada región dependiendo de diferentes factores. Por ello cada país debe establecer su propio perfil microbiológico con el objeto de proponer esquemas adecuados de prevención y tratamiento. Objetivo. Investigar la presencia y concentración subgingival de Porphyromonas gingivalis, Tannerella forsythia, Actinobacillus actinomycetemcomitans, Prevotella intermedia/Prevotella nigrescens, Eikenella corrodens, Campylobacter rectus, Micromonas micros, Fusobacterium spp, Dialister pneumosintes y bacilos entéricos en pacientes con periodontitis en una población colombiana considerando edad, género y nivel socioeconómico. Materiales y métodos. Participaron 183 pacientes: 84 con periodontitis crónica, 59 con periodontitis agresiva y 40 individuos sanos. De cada paciente se obtuvo un grupo de muestras de los seis sitios con mayor profundidad de bolsa que se procesaron por cultivo para el aislamiento e identificación de las bacterias. Resultados. En periodontitis crónica y agresiva se detectaron con alta y similar frecuencia P. gingivalis, T. forsythia, P. intermedia/P. nigrescens, C. rectus, Fusobacterium spp y E. corrodens y con menor y similar frecuencia, M. micros, A. actinomycetemcomitans, D. pneumosintes y bacilos entéricos, principalmente de la tribu Klebsielleae. En los sujetos sanos se encontraron con frecuencia elevada P. intermedia/P. nigrescens, C. rectus y Fusobacterium spp y con frecuencia moderada, M. micros y E. corrodens. Conclusión. Los resultados indican que P. gingivalis, T. forsythia, P. intermedia/P. nigrescens, C. rectus, Fusobacterium spp y E. corrodens constituyen parte importante del perfil microbiológico de las periodontitis en la población colombiana. En la periodontitis agresiva, P. gingivalis se encontró más frecuentemente que A. actinomycetemcomitans.Palabras clave: periodontitis/epidemiología, Porphyromonas gingivalis, bacterias anaerobias, Enterobacteriaceae, Pseudomonadaceae.Subgingival microbiota in chronic and aggressive periodontitis in Bogotá, Colombia: an epidemiological approach Introduction. Periodontitis-associated microbiotas differ in regions around the world and vary with a variety of factors. This suggests that each country must establish its own dental microbiobiotic profile in order to formulate adequate prevention measures and more specific treatments. Objective. The prevalence and proportions of the following microorganisms were investigated: Porphyromonas gingivalis, Tannerella forsythia, Actinobacillus actinomycetemcomitans, Prevotella intermedia/Prevotella nigrescens, Eikenella corrodens, Campylobacter rectus, Micromonas micros, Fusobacterium spp, Dialister pneumosintes and enteric rods. The patients selected had been diagnosed with chronic periodontitis and aggressive periodontitis from clinical populations in Bogotá, Colombia. The variables of age, gender and socioeconomic level were included in the comparisons. Materials and methods. 183 patients were classified in two groups, chronic periodontit...

“…were isolated frequently among patients with GAgP. In GAgP, the occurrence of identification of P. gingivalis varied between 62% and 100% in different populaces (Takeuchi et al, 2003;Gajardo et al, 2005). Comparably, this microorganism was the most frequently found (67.5%) in the currently studied population.…”

“…Examples include the observation of Streptococcus mutans, Actinomyces sp., and Lactobacillus sp. in caries (3,5,21,36), and that of Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola in periodontitis (8,32,34). Taken together, these data suggest an alternative way to simplify microbiota compositional measurement, namely the characterization of a 'subset' bacterial profiles composed of a set of discriminating bacterial species.…”

<b>PCR-dipstick DNA chromatography for profiling of a subgroup of cariesassociated bacterial species in plaque from healthy coronal surfaces and periodontal </b><b>pockets </b>

The onset of plaque-mediated disease, including dental caries and periodontal diseases, is highly associated with compositional change of the resident microflora from the ecological perspective. As specific bacterial profiles have been linked to different disease stages, microbial compositional measurements might therefore have great value for clinical diagnosis. Previously we have reported a dry-reagent strip biosensor-PCR-dipstick DNA chromatography, which utilized molecular recognition of oligonucleotides and biotin-streptavidin, and the optical property of colored microspheres, for semiquantifying a five-membered subgroup of caries-associated bacterial species in supragingival plaque from healthy coronal surfaces of teeth. The present study aimed to evaluate this technique's ability to differentiate microflora by comparing the subset profiles. Sixteen subgingival plaque specimens were pooled from periodontal pockets and analyzed for the composition of Streptococcus mutans, Streptococcus sobrinus, Scardovia wiggsiae, Actinomyces sp. and Veillonella parvula. Detection frequencies, relative abundance of each bacterial species, and the five-membered bacterial profiles were compared between supra-and subgingival groups. The supragingival plaque harbored significantly more of the tested species and higher amount of Actinomyces sp. and V. parvula. In subgingival plaque, the predominance was obscured, since several highly overlapped profiles were found at comparable frequencies. Thus, PCR-dipstick DNA chromatography using the same plaque sample enabled simultaneous profiling of multiple species at species level and facilitated discrimination between anticipated different microflora, making this technique a promising chair-side microbiota profiling method.The ecological plaque hypothesis (18) has revolutionized our view of the etiology of the most prevalent oral diseases, including caries and periodontal diseases. Contrary to the classical medical model, which ascribes an infection to a single microbial pathogene, the new hypothesis suggests that a dysbiosis of the resident oral microflora, driven by an ecological perturbation, leads to plaque-mediated disease. During the transition from oral health to disease state, a dynamic interaction between the resident microflora and the habitat has been evidenced, with numerous bacterial species being implicated (2,3,22,31). A substantial change of the environmental determinants could disrupt the homeostasis of the resident microflora, thereby inducing the prolifera-
