Candida pararugosa isolation from the oral cavity of an Italian denture wearer
2004
Candida pararugosa was first isolated from human feces, but after the initial description no further recovery from humans has been reported. During a study on oral Candida colonization in denture wearers living in Palermo (Italy), we isolated C. pararugosa from a 61-year-old woman without signs of oral candidosis. This constitutes, to the authors' knowledge, the first isolation of C. pararugosa from the oral cavity. After six months, colonization by C. pararugosa persisted, suggesting that this species could be a component of the normal oral microbiota. The identification procedure we used could be useful in elucidating the epidemiology of C. pararugosa and for establishing its clinical sig…
DYSMICROBISM, INFLAMMATORY BOWEL DISEASE AND THYROIDITIS: ANALYSIS OF THE LITERATURE
2015
The human body is colonized by a large number of microbes that are collectively referred to as the microbiota. They interact with the hosting organism and some do contribute to the physiological maintenance of the general good health thru regulation of some metabolic processes while some others are essential for the synthesis of vitamins and short-chain fatty acids. The abnormal variation, in the quality and/or quantity of individual bacterial species residing in the gastro-intestinal tract, is called dysmicrobism. The immune system of the host will respond to these changes at the intestinal mucosa level which could lead to Inflammatory Bowel Diseases (IBD). This inflammatory immune respo…
COLON MICROBIAL COMPOSITION IS CORRELATED WITH THE SEVERITY OF COLITIS INDUCED BY 2,4,6-TRINITROBENZESULFONIC ACID IN MICE.
2016
The objective of this study was to evaluate the changes in some bacterial species of colonic microbiota, the clinical signs and the intestinal changes in mice with 2,4,6-trinitrobenzenesulfonic acid (TNBS) induced colitis. CD-1 male mice were randomly divided into three groups and inoculated intrarectally with saline ethanol or TNBS solutions. ethanol and TNBS treatments induced weight loss accompained by mild and severe inflammation of the colon mucosa, respectively. however, TNBS-treated mice displayed significant differences compared to the saline group in terms of disease activity index and histological scoring. Both ethanol and TNBS groups showed an increased prevalence of escherichia …
THE FINGERPRINT OF THE HUMAN GASTROINTESTINAL TRACT MICROBIOTA: A HYPOTHESIS OF MOLECULAR MAPPING
2017
The precise etiology of Inflammatory Bowel Disease (IDB) remains unclear and several factors are believed to play a role in its development and progression, including the composition of microbial communities resident in the gastrointestinal tract. Human intestinal microbiota are extensive with at least 15,000-36,000 bacterial species. However, thanks to the new development in sequencing and molecular taxonomic methodologies, our understanding of the microbiota population composition, dynamics, and ecology has greatly increased. Intestinal microbiota play a critical role in the maintenance of the host intestinal barrier homeostasis, while dysbiosis, which involves reduction in the microbiome…
THE IMPORTANCE OF INTESTINAL MICROBIAL FLORA (MICROBIOTA) AND ROLE OF DIET
2017
In this article we want to analyze the function of the intestinal microbial flora. In the intestinal environment microorganism "good" microrganisms coexist with "bad". The coexistence between good and bad bacteria is balanced by a mutual action of contrast that has the purpose of maintaining the intestinal microbiota flora in a state of equilibrium. This condition is referred eubiosis. This article will attempt to analyze the beneficial role carried out by eubiotic microbial flora showing the negative effects of dysbiosis.

TARGETED THERAPIES FOR INFLAMMATORY BOWEL DISEASES AND COLORECTAL CANCER: AN INCREASING NEED FOR MICROBIOTA-INTESTINAL MUTUALISM
2015
The involvement of intestinal microbiota and dysbiosis in the pathogenesis for inflammatory bowel disease (IBD) and colorectal cancer (CRC) is a well-established factto be taken into real consideration when developing targeted therapies. This review aims to depict how advances in our understanding of the role of intestinal flora in the pathogenesis of IBD and CRC are shaping up the therapeutic protocols of their management. It is demonstrated of their management. It is demostrated that there is a circadian regulation of colocyte gene expression in response to microbiota. Dysbiosis leading to a decrease in microbiome biodiversity is also described in IBD patients in IBD patients whereby thic…
