 Neocallimastigomycota have also been found in humans.These fungi reproduce in the rumen of ruminants through the formation of zoospores which are released from sporangia.These zoospores bear a kinetosome but lack the nonflagellated centriole known in most chytrids, and have been known to utilize horizontal gene transfer in their development of xylanase (from bacteria) and other glucanases.
