Document Summary
Blastocystis (stramenopiles motile by cilia, heterocont cilia; 1989 patterson; most incidences: pathology: Animal host (fecal); ingested and passed through fecal material. Four commonly described forms are the vacuolar (otherwise known as central body), granular, amoeboid, and cyst forms. The appearance of the organism is largely dependent upon environmental conditions as it is extremely sensitive to oxygen: diagnosis: Antiprotozoal medications, such as paromomycin, or nitazoxanide: genome: Mitochondria like organelle (mlo): 29,270 bp for mitochondrial genome with. Rare incidences, ciliated with an oral fecal route. Found in almost all other large organisms (fish, insects, mammals, etc. ) Primarily is found in the lumen of the large intestines. It can penetrate into the mucosa layer of the large intestine and start to cause ulcers. If stomach is ph 5, the cyst will survive and mutate to trophozoit in small intestine. Contractile vacuoles rare to have these in other organisms. Stool microscopy, sigmoidoscopy (inspection of rectum/sigmoid colon), and tissue biopsy: therapy:
