Obesity represents one of the major problematic health issues worldwide. Recent evidences suggest that obesity is related with the alteration of the oral microbiome. The aim of this study was to measure the salivary bacterial Selenomonas noxia in Duhok population. A total of 155 saliva samples were collected from individuals (aged between 19-35 years) of both genders (86 females and 69 males). The individuals were divided into three groups (obese, overweight, and normal weight) based on their body mass index. Bacterial genomic DNA was extracted from saliva samples. Molecular detections of Selenomonas noxia were performed by the polymerase chain reaction. Among the 155 participants, 34.1% were obese, 26.4% overweight and 39.3% normal weight individuals. The prevalence rate of oral S. noxia among all people was 82.6%. The highest rate of S. noxia was in obese people (86.8%), followed by overweight (85.4%) and normal weight people (77%). The prevalence of S. noxia in overweight people was statistically significant in compare with the normal weight people (p<0.0001). Moreover, the oral carriage of S. noxia was highest among the overweight females (94.5%) followed by obese females (88.9%). However, no significant difference was found compared to males. The result revealed that it is possible to assume that the expansion of S. noxia in saliva is due to obesity. Moreover, the composition of salivary microbiome may lead to the risk that the overweight group is at risk of future obesity. However, further investigations are required with larger sample and participants with different socioeconomic status in order to address the exact link between obesity and oral bacteria. This could lead to a new and promising therapeutic way for improving human's health.

Abstract Background: Both supragingival plaque and saliva are commonly sampled for analysis of microbial communities. However, it remains unclear whether saliva can replace supragingival plaque for microbial studies of caries. There are limited studies on whether the microbiota of healthy first permanent molar (FPM) differs in different caries statuses of deciduous teeth. Herein, the PacBio Sequel platform was used to identify microbiome between three types of oral samples. Additionally, we compared the microbia between children with caries and healthy children in the same kind of microhabitat.Methods: In total, 30 children (aged 7–9 years) were enrolled in this study; 15 of them had dental caries. DNA was extracted from supragingival plaques of deciduous molars, supragingival plaques of maxillary FPMs, and saliva, and the v1–v9 regions of 16S rRNA was amplified. Additionally, PacBio sequencing and bioinformatic analyses were performed.Results: The salivary microbial alpha diversity were lower than that of the supragingival plaque on the teeth, but three was no difference between deciduous teeth and FPMs. Nonmetric multidimensional scaling analysis showed that the saliva samples were mainly scattered in the left side, whereas most plaque samples were distributed on the right. In the same microhabitat , there was no difference in microbial alpha and beta diverty between children with caries and healthy children. For the samples of the deciduous teeth, Streptococcus mutans, Propionibacterium acidifaciens, and Veillonella dispar were more abundant in the children with caries than healthy children, and the first two bacteria showed a positive correlation. For the samples of the FPMs, Selenomonas noxia was more abundant in healthy children than children with caries. But no differentially abundant microorganism were identified between the saliva subgroups. Conclusion:The microbial composition and struction of supragingival plaque was different from that of saliva, and supragingival plaque was found to be the best candidate for studying caries etiology. Streptococcus mutans, Veillonella dispar, and Propionibacterium acidifaciens are highly associated with the existence of deciduous caries. The microbia of the supragingival plaque on the healthy FPMs resemble when the caries status of the deciduous teeth was different, except for the abundance of Selenomonas noxia.

Introduction: Selenomonas noxia (SN) is an important periodontal pathogen, associated with gingivitis and periodontitis. Many studies have found associations between SN and indicators of poor health outcomes, such as smoking, low socioeconomic status and obesity. However, less is known about the prevalence of this organism and more specifically about other oral site-specific locations that may harbor this organism. Methods: Using an existing patient repository (n = 47) of DNA isolated from saliva and other oral sites (n = 235), including the dorsum of the tongue, lower lingual incisor, upper buccal molar and gingival crevicular fluid (GCF), molecular screening for SN was performed. Screening results were analyzed for associations between demographic variables (age, sex, race/ethnicity) and clinical information (body mass index or BMI, presence of orthodontic brackets, primary/mixed/permanent dentition). Results: qPCR screening revealed a total of n = 62/235 sites or 26.3% harboring SN with saliva and GCF (either alone or in combination with one or more sites) most often observed (Saliva, n = 23/27 or 85.18%, GCF, n = 14/27 or 51%). Analysis of site-specific data revealed most positive results were found among saliva and GCF alone or in combination, with fewer positive results observed among the tongue (33.3%), lower lingual incisor (29.6%), and upper buccal molar (25.9%). No significant associations were found between demographic or clinical variables and presence of SN at any site. Conclusions: These results may be among the first to describe site-specific locations of S. noxia among various additional oral biofilm sites. These data may represent a significant advancement in our understanding of the sites and locations that harbor this organism, which may be important for our understanding of the prevalence and distribution of these organisms among patients of different ages undergoing different types of oral treatments, such as orthodontic treatment or therapy.

Selenomonas Noxia

The oral microbiome may be affected by patient medications, disease conditions and systemic disorders. Selenomonas noxia is an anaerobic, motile, non spore-forming, gram-negative rod that has been repeatedly associated with periodontal disease and other disorders, including obesity. Based upon the paucity of evidence regarding oral prevalence, the objective of was to evaluate S. noxia prevalence by sampling saliva from the oral cavity to screen for this pathogen. Using an existing saliva repository, DNA was isolated and screened using quantitative real-time polymerase chain reaction (qPCR). Demographic analysis of study samples and qPCR results was also performed. Approximately half of the samples (n=96) were derived from females (51%) and the majority were from Hispanic patients (62.5%). Following DNA isolation and qPCR screening 37.5% (n=35) were found to harbor S. noxia DNA, which was more prevalent among the samples derived from adults (n=22 or 22.9%) than pediatric patients (n=13 or 13.5%). This study provides novel information regarding the oral prevalence of S. noxia among both pediatric and adult populations from a dental school population. These data are an important part of the overall epidemiologic analysis of this organism and may provide some initial information regarding the risk for periodontal or other health issues related to the presence among these populations.
