Summary

This episode of Side Door follows the dramatic rescue of Lin Mai, a baby Asian elephant at the Smithsonian’s National Zoo who was rejected by her mother and developed a life-threatening gut infection. Host Lizzie Peabody joins zoo staff as they battle the crisis by hand-feeding the calf and performing a fecal microbiota transplant using healthy baby elephant poop sourced from the Columbus Zoo. The story highlights the critical role of gut bacteria in digestion and immunity, culminating in Lin Mai’s recovery and successful bonding with a surrogate mother elephant named Swarna.
