Infections caused by a Sphaerospora sp. resembling S. chinensis are reported for the first time in goldfish (Carassius auratus) from North America. The myxosporean was found in the respiratory epithelium of the gill of pond-reared fish. Spores from stained tissue sections were spherical with an equal mean length and width of 6.3 microns. Spore valves were thickened at the suture which lies in a plane perpendicular to two prominent pyriform polar capsules. The polar capsules were 4.0 x 2.8 microns in length and width. Both monosporous and disporous development within a surrounding "pseudoplasmodium" was detected. Infections caused moderate hyperplasia and occasional necrosis of the respiratory epithelial cells of the gill.

D056890	Eukaryota	One of the three domains of life (the others being BACTERIA and ARCHAEA), also called Eukarya. These are organisms whose cells are enclosed in membranes and possess a nucleus. They comprise almost all multicellular and many unicellular organisms, and are traditionally divided into groups (sometimes called kingdoms) including ANIMALS; PLANTS; FUNGI; and various algae and other taxa that were previously part of the old kingdom Protista.
