| Sumario: | The neotropical otter (Lontra longicaudis) is considered a flagship
species for the conservation of the ecosystems in which it resides
and is currently in a vulnerable state. As a conservation strategy for
this species, rehabilitation, breeding, and reintroduction programs of
captive individuals have been proposed. However, it is likely that the
environment and feeding conditions in captivity result in gut microbial
communities that differ from those in wild animals. Gut microbial
communities have an important role in the physiological performance of
an animal. To determine differences between gut microbial communities
of otters in wild and captive living conditions, the structure and diversity
of their gut bacterial communities were determined using 16S rDNA
molecular markers. Total DNA was isolated from fecal samples of wild
animals from the La Vieja River basin and from captive animals in the
Cali Zoo. As expected, the gut bacterial communities of captive animals
converged to a more similar structure, and their bacterial diversity was
significantly lower than that found in wild animals. |
