Within a country, parasites find a home in contaminated municipal and rural water supplies and in household pets, not to mention in farm animals. Finally, the increase of daycare centers has proven to be a transmission place. The word parasites comes from the Greek para , meaning beside, and sitos , meaning food. This means an animal or plant that lives on or in another organism from which it obtains nutrients. Parasites are larger than bacteria and viruses but usually so small that you cannot see them without a microscope.
Bacteria can also be parasitic.
The parasites are often harmful. Any number of them can infect your gastrointestinal tract. Most parasites produce similar symptoms. According to Ann Louise Gittleman, a certified nutritionist who has worked with parasite patients, a parasite infection can be manifested by any number of signs. These include constipation, diarrhea, gas and bloating, irritable bowel syndrome, joint and muscle aches and pains, anemia, allergies, skin conditions, nervousness, sleep disturbances, teeth grinding, and chronic fatigue.
