Method Primary source abstract: "The status of anaerobic zoosporic (Chytridiomycota) fungi along the entire digestive tract of sheep was assessed both analytically and microscopically. Digest samples were taken from different segments of the digestive tracts of three newly killed sheep that previously had been used in experimental dietary studies. These digest samples were tested for the presence of rumen fungi by assessing the recovery of live fungi from the samples, direct observation of digested plant remains under the scanning electron microscope (SEM), and using a chitin assay as an estimation of fungal biomass. Live anaerobic fungi were recovered from the abomasum, small and large intestine, caecum and faeces of sheep, but not from the digest samples of rumen and omasum."
Comments P.9 right column bottom paragraph: "Fungi represent 10–20% of the rumen microbiota (primary source), [investigators] found that the great majority of the fungal species (81.9%) belonged to anaerobic fungi (Neocallimastigomycota) including most of the genera described so far in ruminants (BNID 117090)." Probably refers to 10%-20% of dry mass
