The primary aim of this monocentric study is to populate the first national microbioma biobank with biological samples (fecal, salivary, urinary and vaginsl samples) subjects suffering from selected disease disease and healthy volunteers. The secondary aim is the characterization of microorganisms of the biobank and study of the microbiota-pathology relationship using meta-omics, in vitro and in vivo approaches, The study plans to enrol 100 subjects at Policlinic of Bari, according to the inclusion/exclusion criteria. The study participation is voluntary, and the subjects have the right to withdraw from the study at any time and for any reason. During the study, 3 visits are planned: Visit 0 (V0), including description of the objectives and procedures study, signature written informed consent, inclusion/exclusion criteria evaluation, medical examination (blood pressure measurement, abdominal and thoracic physical examination), filling in of the anamnestic questionnaire, delivery of kits for the collection of fecal, salivary and urinary material to be reported at Visit 1 and delivery of a 3-day food diary, to be completed autonomously in the days preceding the Visit 1. Visit 1 (V1) - at least 4 days after V0, including delivery of the of the collected biological material (feces, saliva, urine), and of a 3-day food diary, filling in of the new signs and symptoms anamnestic questionnaire and collection of the vaginal swab by medical staff. Telephone evaluation: administration of a "Food Frequency Questionnaire" to assess the subjects' alimentary habits. Standard Operative Procedures (SOP) for samples storing, transport and processing will be adopted to ensure samples stability and grant results validity and quality. Following collections, samples will be processed in different aliquots that will be used for: routine screening; storage in the first Italian human microbiote biobank (I.R.C.C.S. - Istituto Tumori "Giovanni Paolo II", Bari); evaluation of the proteomic, metascriptomic, metabolomic, metagenomic, and metagenetic profile. Furthermore, molecular characterization of pathogenic microorganisms and pathogenic biotypes (pathovars) of commensal species of subjects with selected pathologies will be conducted. Part of the biological material will be used for animal studies on the physiopathological role of the human intestinal microbiota transplanted into mouse models of pathology and Germ-free mouse models (specific animal study protocol developed). The study foresees no more than minimal risk associated with blood sampling procedures. All the necessary measures to avoid any risks / inconveniences resulting from participation of the subject under study will be taken. The study is compliant with Good Clinical Practice. Study protocol and all related documents have been approved by approved by the Independent Ethics Committees (IEC) of the involved clinical sites. To ensure the protection and confidentiality of the participants' data, all study activities will be carried out in accordance with the European General Data Protection Regulation, Regulation (EU) 2016/679, which repeals Directive 95/46/EC.
