culture media for periodontal pathogens

Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis[7–9], Tannerella forsythensis[10,11], Prevotella inte… Usually blood agar or serum has been the base for the design of selective media (11, 16, 23). By continuing you agree to the use of cookies. (A) Principal coordinates analysis (PCoA) of transcriptional profiles from four periodontal pocket samples (chronic periodontitis) and laboratory cultures on three different media. Before mechanical treatment (scaling and root planning), A. actinomycetemcomitans was detected by Dentaid-1 and TSBV in the same patients and showed similar recovery rates.

Anaerobic culture of severe early childhood caries revealed a widely diverse microbiota, comparable to that observed using cloning and sequencing. In the last few years, substantial evidence has emerged that Actinobacillus actinomycetemcomitans may be, along with Porphyromonas gingivalis, a major oral putative pathogen, as judged by this organism's rare occurrence in periodontally healthy individuals (25). These primers gave an expected amplification product of 557 bp. The classification of periodontal pathogens was tried to figure out by many researchers. Moreover, it allows for the direct detection of catalase activity on the primary isolation plate, facilitating the presumptive identification of A. actinomycetemcomitans(23). Preliminary work carried out in our laboratory indicated that BHIA by itself is an excellent nutritive base that allows for good growth of pure cultures of the bacteria. The genusActinobacillus is included in the Pasteurellaceaefamily. The human oral cavity is colonized by at least 300 different bacterial species [1,2], most of which are innocuous. Periodontal pathogens such as P. gingivalis, Tannerella forsythia, and Treponema denticola are asaccharolytic and strongly proteolytic. Dentaid-1 is a low-cost, noninhibitory formula for the improved diagnosis and monitoring of patients subgingivally infected by this important oral putative pathogen. actinomycetemcomitans. Furthermore, some strains belonging to other gram-negative species, mainly H. aphrophilus and H. paraphrophilus, were suppressed. Bacterial counts were numbered as CFU/milliliter. were developed. Additionally, 20 clinical isolates from our laboratory were included. Res. It was designed to confirm the following expectations: optimal growth of A. actinomycetemcomitans and suppression of oral flora that should be equal to or better than what is observed when using TSBV medium as the reference medium. Recent studies revealed that the effects of periodontal pathogens on the production of IL-8 from epithelial cells also vary (6, 18). The contaminant flora (rest of the flora) was quantified in positive samples. Anaerobic culture of initial periodontitis showed overlap in the microbiota with gingivitis, and added Selenomonas noxia and Filifactor alocis as putative periodontal pathogens. The mean RGSA values for A. actinomycetemcomitans on TSBV and Dentaid-1 were 0.81 (Standard deviation [SD] = 1.61) and 0.06 (SD = 0.11), respectively. Anaerobic culture is employed routinely in the primary isolation of periodontal pathogenic bacteria. Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses.Viruses that specifically infect bacteria - bacteriophages - are most common in the oral cavity. Comparison between gene expression in periodontitis and laboratory culture for Porphyromonas gingivalis. After incubation for 72 h at 37°C in a 5% CO2incubator, the plates were examined for the presence and enumeration ofA. ), and the AnaeroPack (Mitsubishi Gas Chemical America, Inc., New York, N.Y.) systems to grow … This microorganism requires nutritionally complex media for growth, and therefore the media for its primary isolation usually include blood agar or serum in their base.

The 22 strains were maintained at −85°C and subcultured three times at 48-h intervals on brain heart infusion agar (BHIA) (Difco Laboratories, Detroit, Mich.) before testing. The dominant microbiota of dental caries differs from that of periodontitis. An A. actinomycetemcomitans presumptive identification was first made on the basis of colonial morphology. In conclusion, the new proposed medium, Dentaid-1, improves the detection of A. actinomycetemcomitans inexpensively, with a noninhibitory formula, and can be of considerable aid in microbiological diagnosis and in monitoring patients subgingivally infected with this bacterium. Colonization into the subgingival plaque by certain species can lead to infection of the periodontium resulting in gingivitis and periodontitis [3,4]. Subsequently, lactose-negative colonies resembling A. actinomycetemcomitans were confirmed by using a species-specific PCR (8, 20). Detection of periodontal pathogen Porphyromonas gingivalis by loop-mediated isothermal amplification method Hiroshi Maeda Division of Periodontal Science, Department of Patho-Physiology, Okayama University Graduate School of Medicine and Dentistry, 2-5-1 Shikata-cho, Okayama 700-8525, Japan. PCR amplification was carried out in a reaction volume of 25 μl consisting of 3.2 μl of the initial sample in water for a final volume of 20.1 μl and 4.9 μl of the reaction mixture containing 1× PCR buffer [67 mM Tris-HCl, pH 8.8; 16 mM (NH4)2SO4, 0.01% Tween 20; 1.5 mM MgCl2], 0.6 U of EcoTaq DNA polymerase (ECOGEN), 0.25 mM concentrations of the deoxynucleoside triphosphates, and 80 pmol of each primer. With periodontal disease, a large number of species are identifiable in the periodontal pocket, and many more are as yet unknown because they have not been cultured. Well studied Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis.. Plates were incubated in a CO2 incubator (5% CO2) (Sanyo Electric Co., Ltd.). MATERIAL AND METHODS:Blood samples were collected from thirty-six subjects with different periodontal status (17 … Periodontal disease is a chronic inflammation of tooth-supporting tissues, and the destruction of these tissues results in tooth loss. Washington, DC 20036 Since periodontal diseases result from complex interactions of multiple microorganisms, it is essential to investigate the interactions between different periodontal bacteria and epithelial cells. Can one acquire periodontal bacteria and periodontits from a family member? Specific pathogens associated with various forms of periodontal disease are identified and antibiotic sensitivities and b-lactamase production are determined to assist the clinician in appropriate interventive strategies.
