Blastocystis are parasites naturally found living in the gastrointestinal tracts of species as diverse as humans, farm animals, birds, rodents, reptiles, amphibians, fish, and even cockroaches. Infection caused by Blastocystic species causes blastocystosis in humans. Transference occurs when infected fecal matter is ingested so transmission of this parasite is strictly via the fecal-oral route.

Symptoms associated with the infection are diarrhea, nausea, abdominal cramps, bloating, excessive gas, and anal itching. Most cases of the infection are often incorrectly diagnosed as irritable bowel syndrome.

  • Always wash your hands after using the bathroom or playing with your pets/animals.
  • Do not allow pets to lick your face.
