This document discusses a longitudinal study of the microbiome and intestinal parasites of rufous mouse lemurs in Madagascar over 2-3 years. Key findings include:
1) The nematode community was stable at the population level but variable between individuals.
2) The microbiome was stable at the population level but highly variable between individuals over time.
3) Intestinal parasite presence generally did not affect the microbiome, except in some interactions still under investigation.

9. Significant variables
- Infracommunity:
- All putative species uniformly distributed over hosts
- No effect of previous infection
- Component community:
- Prevalence higher in 2011 than in 2012
- No effect of sex or site
