Isolation of Malassezia yeasts from dogs with gastrointestinal disease undergoing duodenal endoscopy.

Based on a literature search, this is the first report of isolation of M. pachydermatis, M. sympodialis, K. slooffiae and K. telluris from the canine duodenum. Further studies are needed to determine whether these are resident or transient fungi in the canine duodenum and whether their presence has a pathogenic effect on the host.
