⭕Characteristics: Considered non-pathogenic (does not cause disease) and is commonly found in the large intestine.
⭕Lifespan: Unknown.
▪Cyclospora cayetanensis (protozoa)
⭕Transmission: Commonly spread through fecal-contaminated food or water. Does not spread from person to person, except through fecal exposure. Often found on imported produce.
⭕Lifespan: Information not available.
▪Dientamoeba fragilis (protozoa)
⭕Transmission: The exact method of transmission is not well understood, but experts speculate it spreads through fecal-contaminated food or water.
⭕Lifespan: Unknown.
▪Endolimax nana (protozoa)
⭕Transmission: Commonly spread through fecal-contaminated food or water.
⭕Lifespan: Unknown.
▪Entameoba coli (protozoa)
⭕Transmission: Not to be confused with E. coli, this organism is commonly transmitted through fecal-contaminated food or water and is considered non-pathogenic.
⭕Lifespan: Inside the host, it survives for days to weeks, although its larvae can live up to 3-4 months outside the host. Mature Entamoeba coli will not survive outside its host.
▪Pentatrichomonas hominis (protozoa)
⭕Transmission: Commonly spread through fecal-contaminated food or water and carried by cats and dogs.
⭕Lifespan: Unknown within the human body, but outside the host, this parasite can survive for several days.
▪Ancylostoma duodenale and Necatur americanus (hookworms)
⭕Transmission: Spread through skin contact with or ingestion of contaminated soil. Can also be transmitted by cats and dogs.
⭕Lifespan: Ancylostoma duodenale can survive inside humans for up to 1 year, while Necator americanus typically survives up to 5 years in humans, though it has been recorded to live up to 15 years.
▪Ascaris lumbricoides (roundworm)
⭕Transmission: Commonly spread through fecal-contaminated food or water.
⭕Lifespan: 1-2 years in humans.
▪Trichuris trichiura (whipworm)
⭕Commonly transmitted through fecal-contaminated produce, and person-to-person contact.
⭕Lifespan: 1-2 years in humans.
▪Taenia species (tapeworm)
⭕Transmission: Commonly spread through fecal-contaminated and undercooked pork (Taenia solium) and beef (Taenia saginata).
⭕Lifespan: Taenia solium can survive in humans for 10-20 years, while Taenia saginata can live up to 25 years!
