Donor screening for fecal microbiota transplantation with a direct stool testing-based strategy: a prospective cohort study.

Fecal microbiota transplantation (FMT) is effective against recurrent Clostridioides difficile infection (rCDI), but its safety is jeopardized by the potential transmission of pathogens, so international guidelines recommend either a quarantine or a direct stool testing. Whereas reports of the quarantine-based approach are emerging, data on the direct testing-based approach are not available. Our aim is to report outcomes of a donor screening framework for FMT including direct stool testing.

Fecal Microbiota Transplantation and Other Gut Microbiota Manipulation Strategies.

The gut microbiota is composed of bacteria, archaea, phages, and protozoa. It is now well known that their mutual interactions and metabolism influence host organism pathophysiology. Over the years, there has been growing interest in the composition of the gut microbiota and intervention strategies in order to modulate it.

"Bacterial Consortium": A Potential Evolution of Fecal Microbiota Transplantation for the Treatment of Infection.

Fecal microbiota transplantation (FMT) consists of infusion of feces from a donor to a recipient patient in order to restore the resident microbial population. FMT has shown to be a valid clinical option for infections (CDI). However, this approach shows several criticalities, such as the recruiting and screening of voluntary donors.

Rummeliibacillus suwonensis: First Time Isolation from Human Feces by Culturomics.

Gut microbiota is a complex ecosystem composed by trillions of microorganisms that are crucial for human health or disease status. Currently, there are two methodological options to explore its complexity: metagenomics and culturomics. Culturomics is an approach that uses multiple culture conditions (days of incubation, enrichment factors and growth temperature) and MALDI-TOF mass spectrometry for the identification of bacterial species and sequencing when this method fails.
