Ensembl refined their pipeline that imports data on host-pathogen interactions from PHI-base, improving the specificity. These data map PHI-base terms to genes, indicating how these genes are linked to phenotypes such as loss of pathogenicity or chemical sensitivity, which are involved in how the pathogen interacts with its host. We have PHI-base terms attached to genes in thousands of species in Ensembl Bacteria, Fungi and Protists. You can search for PHI-base terms in Ensembl, find them on genes and use them in BioMart.
