Restoring
microorganisms in the gut to a youthful age was linked to improved
stroke recovery in old mice, according to a new study presented at the
American Stroke Association’s International Stroke Conference 2016.
Noting that different bacteria present in the gut change with age,
researchers from the University of Connecticut in Mansfield,
Connecticut, used fecal transplants to deliver a “young” set of bacteria
to mice that were 18 to 20 months old as well as to mice just 3 or 4
months old, while another group of mice received an “aged” set of
bacteria in each of those two age groups. The mice were first given an
antibiotic to suppress their own microbial makeups and allow the new
sets of gut bacteria to flourish. Follow–up behavioral and neurological
tests showed that older mice with “young” sets of bacteria recovered
from the induced stroke better than their peers with “aged” bacteria.
Meanwhile, death rates after the stroke were particularly high —
exceeding 50 percent — in young mice with “aged” bacterial makeups,
researchers said.
