Extra-Intestinal Blastocystis Infection in Duck

Veterinary researchers from Cambridgeshire, UK have reported a case of extra-intestinal Blastocystis infection observed in a duck.  Although Blastocystis is often thought to occur exclusively in the gastrointestinal tract, samples taken from a facial swelling of the duck in question were found ro bear a morphological similarity to Blastocystis.  Subsequent PCR testing showed that the subtype was consistent with Blastocystis sp. subtype 7.    The full study was published in the Journal of Veterinary Diagnostic Investigation.
