Host species Species from which microbiome was sampled. Contact us to have more species added.
Homo sapiens
Body site Anatomical site where microbial samples were extracted from according to the Uber Anatomy Ontology
Saliva Sailva normalis,Saliva atomaris,Saliva molecularis,Salivary gland secretion,Saliva,saliva
Condition The experimental condition / phenotype studied according to the Experimental Factor Ontology
Population Population,population
Group 0 name Corresponds to the control (unexposed) group for case-control studies
Kwepe
Group 1 name Corresponds to the case (exposed) group for case-control studies
Tshwa
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Khoe-Kwadi-speaking foragers from the Tsholotsho District of western Zimbabwe. They traditionally relied on foraging but were forced to leave their hunting grounds in Hwange National Park during the early 20th century, leading to social marginalization.
Group 0 sample size Number of subjects in the control (unexposed) group

Source: Supplementary Table 4 and 5

Description: Differential abundance (FDR adjusted p_value <0.05) between populations according to DESeq2 analysis. Positive values in the log2FoldChange indicate taxa enriched in the first population of the comparison, and negative values represent taxa enriched in the second population.
