A case of intestinal cryptosporidiosis was diagnosed in 3 to 30 days old goat kids in northern Taiwan. The main signs were watery diarrhea, depression, weakness, inability to stand, and anorexia. Acid-fast staining on fecal samples revealed numerous 4 μm pink or red organisms compatible with ”Cryptosporidium” spp.. Light microscopy detected many cryptosporidial organisms primmarily attaching to the surface of intestinal epithelium. Electron microscopy demonstrated trophozoite, schizonts, and oocysts of cryptosporidia. Fifteen of 30 affected goat kids died despite intensive treatment.
