Fig. 3From: More than just a gut feeling: constraint-based genome-scale metabolic models for predicting functions of human intestinal microbesModes of interspecies interactions as modeled before. Pairwise interactions only account for two species to share metabolites. Multispecies models allow sharing of metabolites between more than two species. Microbiota-host interaction models lump all the microbial species into one meta-model and model the interaction with the host. Microbe-microbe and microbiota-host interactions are multilevel models that take into account microbial interactions and interactions with the hostBack to article page
