Identificación de microbiota bucal en caninos en estado de abandono / Identification of Bucal Microbiota in Canines in State of Abandonment

Resumen Objetivo. Describir la microbiota que se encuentra en la cavidad bucal de caninos en condición de abandono de la Fundación Razas Únicas en el municipio de Chía -Cundinamarca. Métodos. Para el estudio se tomaron 29 muestras orales con escobillón a 23 caninos de la Fundación Razas Únicas del municipio de Chía - Cundinamarca. 23 muestras se recolectaron para identificación de bacterias aerobias y anaerobias facultativas, las cuales se transportaron en medio líquido tripticasa soya y 6 muestras para recuperación de bacterias anaerobias estrictas transportadas en medio VMGA-III. El aislamiento de los microorganismos se realizó en medios selectivos y la identificación con el sistema BD BBL™ Crystal™. Resultados. De las 29 muestras analizadas se aislaron 59 bacterias, entre ellas 15 géneros y 15 especies diferentes como; Escherichia coli, Proteus mirabilis, Citrobacter freundii, Enterobacter sakazakii, Enterobacter cloacae, Enterococcus durans, Enterococcus faecalis, Eikenella corrodens, Porphyromonas endodontalis, Fusobacterium spp y Capnocytophaga spp. De acuerdo con la revisión de la literatura, las bacterias anaerobias encontradas están principalmente relacionadas con enfermedad periodontal y las enterobacterias con contaminación oro-fecal.

Abstract Objective. To describe the microbiota found in the oral cavity of canines in condition of abandonment of the Razas Únicas Foundation in the municipality of Chía - Cundinamarca. Methods. For the study, 29 oral samples were taken with a brush from 23 canines from the Razas Únicas Foundation of the municipality of Chía - Cundinamarca. 23 samples were collected for identification of facultative aerobic and anaerobic bacteria, which were transported in soybean tripticase liquid medium and 6 samples for recovery of strict anaerobic bacteria transported in VMGA-III medium. The isolation of the microorganisms was carried out in selective media and identification with the BD BBL™ Crystal™ system. Results. From the 29 samples analyzed, 59 bacteria were isolated, including 15 genera and 15 different species such as Escherichia coli, Proteus mirabilis, Citrobacter freundii, Enterobacter sakazakii, Enterobacter cloacae, Enterococcus durans, Enterococcus faecalis, Eikenella corrodens, Porphyromonas endodontalis, Fusobacterium spp and Capnocytophaga spp. According to the review of the literature, the anaerobic bacteria found are mainly related to periodontal disease and the enterobacteria with oral-fecal contamination.

Microorganismos inusuales en placa subgingival de pacientes con periodontitis crónica / Unusual microorganisms in subgingival plaque of patients with chronic periodontitis

Fundamento: en ambientes subgingivales de pacientes con periodontitis crónica se han encontrado microorganismos inusuales que incluyen bacilos entéricos gramnegativos y levaduras. En estos pacientes la terapia mecánica o antimicrobiana puede ser ineficiente para tratar o controlar la enfermedad periodontal. La característica que comparten los microorganismos inusuales es la de ser patógenos oportunistas, ya que aprovechan las condiciones de inmunodepresión para originar o agravar una enfermedad. Objetivo: presentar la prevalencia de microorganismos inusuales en placa subgingival de pacientes con periodontitis crónica en una población colombiana. Método: se evaluaron 76 pacientes sistémicamente sanos que asistieron a las clínicas odontológicas de la Facultad de Odontología de la Universidad de Antioquia. Las muestras subgingivales se procesaron mediante cultivo. Resultados: se observaron bacilos entéricos gramnegativos en 20 (26.31 %) pacientes y levaduras en 10 (13.2 %). Conclusiones: estos hallazgos tienen implicaciones terapéuticas importantes que deben tenerse en cuenta para el manejo de los pacientes con enfermedades periodontales.

Background: subgingival environment of patients with chronic periodontitis have been found unusual microorganisms including Gram-negative enteric bacilli and yeasts. Mechanical or antimicrobial therapy in these patients may be inefficient to treat or to control periodontal disease. The common feature unusual microorganisms share is to be opportunistic pathogens, taking advantage of immunosuppression conditions to cause or aggravate the disease. Objective: to present the prevalence of unusual microorganisms in subgingival plaque of patients with chronic periodontitis in a Colombian population. Method: 76 systemically healthy patients who were presented in the dental clinic at the Dental School of Antioquia University were evaluated. Subgingival samples were processed by cultivation. Results: enteric Gram-negative bacilli in 20 patients and yeasts in 10 were observed. Conclusions: these findings have important therapeutic implications that must be taken into account for patients management with periodontal diseases.

Achados bacterianos encontrados na secreção da otite média cronica: estudo comparativo entre o colesteatoma (OMCC) e a otite média cronica simples (OMCS) / Bacterial findings found in the chronic otitis media secretion: comparative study between cholesteatoma (OMCC) and simple chronic otitis media (SCOM)

Introdução: Foi feita uma comparação na frequencia com que os patogenos infectantes foram detectados na supuração causada pelo colesteatoma e pela otite crônica simples no período de 2006 a 2008. Objetivo: Fazer um estudo comparativo entre os achados bacterianos encontrados na secreção da otite crônica simples e a colesteatomatosa. Método: Foram estudados a bacterioscopia de 83 pacientes (125 orelhas) portadores de otite média crônica, sendo 43 (52 orelhas) com colesteatoma e 40 (73 orelhas) com otite crônica simples, com predominância de idade dos 16 aos 20 anos. A duração da otorreia variou entre 2 meses e 10 anos. Para a colheita do material utilizamos um equipamento bastante pratico com caldo de tioglicolato dentro e fora enviados ao laboratório por um período máximo de até 18 horas. Resultados: O S. aureus foi mais frequente na otite crônica simples, enquanto que os anaeróbios foram mais frequentes no colesteatoma. A P. aeruginosa foi mais frequente na otite crônica simples e o Corynebacterium sp. apresentou maior frequencia no colesteatoma. o S. epidermidis apareceu com frequencias iguais em ambas as doenças otológicas. Conclusão: Não encontramos mudanças notáveis na bacteriologia dessas duas doenças. Na otite crônica simples os achados mais frequentes foram S. aureus, Pseudomonas sp. e fungos. No colesteatoma os achados mais frequentes foram os Anaeróbios e o Corynibacterium sp. A frequencia de aparecimento para S. epidermidis, Klebisiela sp. e Streptococcus sp. foi igual em nosso estudo.

Introduction: This study carried out a comparison in the frequency with which the infecting pathogens were detected in the suppuration caused by cholesteatoma and simple chronic otitis media in the period from 2006 to 2008. Objective: To carry out a comparative study between the bacterial findings found in the simple and cholesteatomatous chronic otitis media secretion. Method: We studied the bacterioscopy of 83 patients (125 ears) with chronic otitis media, 43 (52 ears) with cholesteatoma and 40 (73 ears) with simple chronic otitis, and age prevalence from 16 to 20 years. The duration of otorrhea ranged between 2 months and 10 years. For collection of the material we used very practical instrument with tioglicolate broth inside and outside sent to the laboratory for a maximum period of until 18 hours. Results: The S. aureus was more frequent in the simple chronic otitis, and the anaerobic were more frequent in the cholesteatoma. The P. aeruginosa was more frequent in the simple chronic otitis and the Corynebacterium sp. presented a higher frequency in cholesteatoma. The S. epidermidis appeared with the same frequencies in both otologic diseases. Conclusion: We did not find any critical changes in the bacteriology of either disease. In the simple chronic otitis, the most frequent findings were S. aureus, Pseudomonas sp. and fungi. In the cholesteatoma, the most frequent findings were the Anaerobios and Corynibacterium sp. The frequency of S. epidermidis, Klebisiela sp. and Streptococcus sp. was the same in our study.
