NCT03460392

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
