This basically tells us that certain members of the Bacteroidetes family seem to be more aggressive when compared to different members of
the microbiota of obese mice.

Separate groups
of germfree
mice were colonized with uncultured fecal
microbiota from each member
of four twin pairs discordant for obesity or with culture collections from an
obese (Ob) or lean (Ln) co-twin.
Cohousing
mice harboring an
obese twin's
microbiota (Ob) with
mice containing the lean co-twin's
microbiota (Ln) prevented the development
of increased body mass and obesity - associated metabolic phenotypes in Ob cage mates.
Moreover,
obese - phenotype
mice were invaded by members
of the Bacteroidales from the lean
mice, but, happily, the lean animals resisted invasion by the
obese microbiota.
As a result, these researchers found that one strain
of mice which were genetically prone to become
obese became resistant to excess weight gain after their populations
of gut
microbiota were transformed simply by an sharing an environment with other
mice.

Their procedure involved infecting
mice without
microbiota with either
microbiota of obese or lean
mice.
In a later step
of this study,
microbiota from
obese mice fed with a western diet were transferred to the
microbiota - free
mice.
