Eukaryotic Diversity in Wild Baboon Gut Microbiomes
Eukaryotic organisms, including fungi, protists, and helminths, play crucial roles in the gut microbiomes of mammals. In wild baboons from the Amboseli ecosystem, shotgun metagenomic sequencing revealed the presence of various eukaryotic taxa, primarily from the kingdoms Protista, Chromista, and Fungi. Notably, 90.7% of analyzed samples contained protists, while 46.7% showed evidence of Chromista, and 20.3% of samples had fungal presence (Chege et al., 2025). This study identified the most prevalent species, including Entamoeba coli, Enteromonas hominis, and Blastocystis subtypes, which suggest a complex interaction between these microorganisms and their host.
The methods used to analyze gut eukaryotic diversity were comprehensive, utilizing both EukDetect and gutprotist-search pipelines, which provided robust frameworks for identifying and characterizing the eukaryotic communities present in the baboons’ gut microbiomes.
| Eukaryotic Taxon | Prevalence (%) |
|---|---|
| Entamoeba coli | 74.66 |
| Enteromonas hominis | 53.33 |
| Blastocystis subtype 3 | 38.66 |
| Iodamoeba sp. | 36.00 |
| Chilomastix mensnili | 34.70 |
Impact of Social Groups on Gut Microbial Composition
Social structures significantly influence the composition of gut microbiomes in wild baboons. In a study analyzing the gut eukaryotic diversity between two social groups, it was found that social group membership explained 11.2% of the global diversity in gut eukaryotic species composition. Baboons in larger social groups exhibited greater eukaryotic diversity than those in smaller groups (Chege et al., 2025). This finding indicates that social interactions and group dynamics may play a critical role in shaping gut microbiota, likely through mechanisms such as grooming, shared foraging, and social transmission of microorganisms.
Seasonal Changes Affecting Gut Eukaryotic Communities
While the influence of social group dynamics is profound, seasonal changes also play a role in the composition of gut eukaryotic communities. However, in contrast to bacterial communities, which have shown significant seasonal variation, eukaryotic community composition in wild baboons did not exhibit substantial differences between the wet and dry seasons in this study (Chege et al., 2025). This observation suggests that eukaryotic communities may be more stable in the face of seasonal environmental changes compared to their bacterial counterparts.
Predominant Eukaryotic Species in Wild Baboons
The predominant eukaryotic species in the baboon gut microbiome have important health implications. The presence of Entamoeba coli and various Blastocystis subtypes has been commonly associated with both commensal and pathogenic roles in primates (Chege et al., 2025). Understanding the abundance and diversity of these eukaryotic taxa can provide insights into the health status of the baboons, as certain species may influence immune responses and susceptibility to diseases.
Implications for Primate Health and Microbiome Research
The findings from studies investigating the gut eukaryotic diversity in wild baboons underscore the importance of considering eukaryotic members alongside bacterial communities in microbiome research. As these microorganisms can impact host health, understanding their roles and interactions is crucial for developing effective conservation and management strategies for wild primate populations. Furthermore, these insights contribute to the broader field of microbiome research, highlighting the need for a more comprehensive approach to studying the complex interactions within host-associated microbiomes.
