Dynamic changes in intestinal microbiota in young forest musk deer during weaningOriginal paper
Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease, four years before the first published case study.

Researchers examined how the intestinal microbiota of young forest musk deer changes across the weaning transition. They compared 15 deer sampled 10 days before and 10 days after weaning.
How was it studied?
The team used high throughput 16S rRNA gene sequencing on fecal samples from the pre-weaning and post-weaning periods. Linear discriminant analysis effect size (LefSe) identified taxa that differed most between the two groups.
What did they find?
Microbiota diversity was significantly higher after weaning than before. Firmicutes, Bacteroidetes and Verrucomicrobia dominated both periods, but post-weaning deer had more Actinobacteria, Spirochaetes, Ruminococcaceae_UCG-005, Treponema and Prevotella, while Bacteroidetes was relatively more abundant before weaning.
Why it matters
The findings establish a baseline for how gut microbiota shifts during weaning in this endangered species. This may help inform husbandry and health monitoring during a known stress period for young forest musk deer.
