The Role of Human Microbiota in Myasthenia Gravis: A Narrative Review
2023
Myasthenia gravis (MG) is an autoimmune neuromuscular disease characterized by fluctuating weakness of the skeletal muscles. Although antibodies against the neuromuscular junction components are recognized, the MG pathogenesis remains unclear, even if with a well-known multifactorial character. However, the perturbations of human microbiota have been recently suggested to contribute to MG pathogenesis and clinical course. Accordingly, some products derived from commensal flora have been demonstrated to have anti-inflammatory effects, while other have been shown to possess pro-inflammatory properties. In addition, patients with MG when compared with age-matched controls showed a distinctive …
Study of oral microbiota and diet as casual factors of Black Stains in the pediatric patient
2019
The aim of the following study is to identify and quantify microorganisms in the saliva of black stain patients using species-specific probes for Actinomyces israelii, Actinomyces naeslundii, Streptococcus mutans and Lactobacillus spp, as well as a universal probe for bacterial 16S rDNA, to obtain the figure of the total bacterial counts (for test and control group). This study represents a first phase of the research line on extrinsic tooth pigmentation on developmental age patients. Materials and methods. The selected sample is composed of 20 subjects aged between 2 and 15 years and in good general and oral health among the patients included in a dental examination trial at the Department…
ORAL MICROBIOTA: CHARACTERISTICS, RELATED PATHOLOGIES AND FUTURE PROSPECTS
2020
The oral microbiota is represented by the set of bacteria and microrganisms that reside in the oral cavity. It is formed from bird and stabilizes during the period of permanent dentition. The oral microbiota poresents from 500 to 700 bacterial species, belonging to six main phyla, Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria, Spirochaetes and Fusobacteria. These bacteria partecipate in the formation of dental plaque, a sort of biofilm that deposits on the rigid surfaces of the oral cavity, and contributes to the healthy maintenance of the oral cavity. An alteration of the oral microbiota contributes to the pathogenesis of periodontitis, caries, gingivitis and also of systemic d…
