Brief Summary
The aim of the present study is to characterize the bacterial composition (microbiota) colonizing to the human body in different physio - pathological conditions (lifestyle, motor activity, surgical operations, probiotic and prebiotic consumption, antibiotic therapies, chemotherapeutic therapies), nervous and musculoskeletal diseases, gastrointestinal and metabolic disorders , oral and vaginal diseases, etc.). In particular, they will be investigate:
- the changes in the bacterial abundance
- the potential microbial interactions with the human host
- the microbial networks describing on the bacterial interactions within a specific composition of the human microbiota

Outcome Measures
Primary Outcomes (1)
Bacterial abundances calculated by mean of Operational Taxonomic Unit (OTU) count
It is a measure of the bacterial amount
Up to 24 weeks
Secondary Outcomes (4)
Chao's indices estimated on the total OTU amount
Up to 24 weeks
Simpson's index (D) estimated on the total OTU amount
Up to 24 weeks
Shannon's index estimated on the total OTU amount
Up to 24 weeks
The OTU abundances will be used to calculate an adjacency matrix based on the Spearman's correlation coefficient (rs) among different bacterial genus
up to 24 weeks
Study Arms (7)
Neurological and behavioral disorders
Subjects with neurological or behavioral disorders such as Tourette syndrome are enrolled.
Subjects affected by bone diseases
Subjects affected by bone diseases such as infective osteomyelitis or osteoporosis are enrolled.
Dysmetabolic and/or endocrine disorders
Patients with endocrine disorders, such as thyroid disfunctions, or with metabolic disorders, including diabetes mellitus,are enrolled.
Subjects performing agonistic activity
Subjects performing physical activity at agonistic level are enrolled.
Gastroenteric disorders
Subjects affected by gastric and/or enteric disorders are enrolled.
Prolonged antibiotic therapy
Patients subjected to prolonged antibiotic therapies and undergone a variety of surgical procedures are enrolled.
Healthy subjects
Subjects without any known ongoing disease are enrolled.
Interventions
To evaluate the effects of a specific event (i.e. surgical operation) or therapy (i.e antibiotic treatment) over time;
Eligibility Criteria
For each cohoort 15 healthy subjects will be enrolled (controls), for a total of 90 subjects. The study involves the recruitment of 180 subjects (90 pathological and 90 healthy and recruited
