Table 1.

Several differentially abundant taxa were associated with the ruminant-associated and dog-associated fecal genetic marker abundance in household soil/dust. The taxa that were more abundant with the microbial source tracking (MST) marker gene (top row) are differentiated from those that were less abundant with the MST gene (bottom row). An asterisk (*) indicates significance identified via Microbiome Multivariable Associations with Linear Models (MaAsLin2) testing, which was used for continuous variables. Those taxa that are not marked were identified via linear discriminant analysis effect size (LEfSe), using 2 groups, presence or absence of the marker gene

	Ruminant-associate fecal marker	Dog-associated fecal marker
Taxa abundance increased with MST gene	Clostridium perfringens*, Streptococcus infantarius*, Campylobacter jejuni*, Anaerostipes, Anaerostipes hadrus, Bacteroides salanitronis, Bacteroides cellulosilyticus, Bacteroides helcogenes, Clostridium bolteae, Campylobacterales, Unspecified Bacteria	Barnesiella viscericola*
Taxa abundance decreased with MST gene	NA	Parabacteroides distasonis, Parabacteroides, Lachnoclostridium phocaeense
