The intestinal disease cyclosporiasis is caused by the protozoan Cyclospora cayetanensis. It is endemic to tropical and subtropical regions and therefore uncommon in the United States, although there have been outbreaks associated with contaminated produce imported from regions where the protozoan is more common.

Giardia duodenalis, also known as Giardia intestinalis and Giardia lamblia, is a flagellated parasitic microorganism, that colonizes and reproduces in the small intestine, causing a diarrheal condition known as giardiasis. The parasite attaches to the epithelium by a ventral adhesive disc or sucker, and reproduces via binary fission. Giardiasis does not spread via the bloodstream, nor does it. Intestinal worms, or parasitic worms, are simple organisms that feed off the human body. Many people recognize the more common varieties, such .
Human intestinal parasites are those that host themselves in the intestinal tract of the human body. According to the University of Maryland Medical Center, there are two types of intestinal parasites 1. Helminths, such as tapeworms, pinworms and roundworms, are worm-like and large enough to be visualized without the use of special equipment. Gastrointestinal parasitism is a common problem in cats, with prevalence rates as high as 45 percent. The parasites can be wormlike (e.g., stomach worms, roundworms, hookworms, tapeworms) or one-celled (e.g., Isospora, Giardia, Toxoplasma) organisms. The signs associated with parasite infections are fairly nonspecific, such as a dull haircoat, coughing, vomiting, diarrhea.

It is the most frequent protozoan intestinal disease in the US and the most common identified cause of water-borne disease associated with breakdown of water purification systems, drinking from contaminated streams, travel to endemic areas (Russia, India.
Giardia, Trichomonas, Chilomastix and Dientamoeba are classified as flagellates; Balantidium coli is a ciliate, and Isospora and Cryptosporidium are coccidians. All are intestinal parasites that are transmitted by the fecal-oral route, except for T vaginalis, which is usually spread by sexual contact.
The intestinal protozoa of humans belong to four groups: Amoeba, Flagellates, ciliates, and coccidian. Most and almost all protozoa are small in size means they are microscopic.
They varies from 5 - micrometers, depending on species, among the many species of intestinal protozoa. on taxonomy) is a protozoan parasite that colonizes the upper portions of the small intestine. It has a worldwide distribution and is the most common protozoan isolated from human stools.
The incidence is estimated at million clinical cases per year. In fact, it. Humans harbor several species of commensal protozoans, that colonize in the intestinal tract such as Entamoeba dispar, Entamoeba hartmanni, Entamoeba moshkovskii, Entamoeba polecki, Endolimax nana, Iodomoeba butschlii (Ortega, ).
•Parasitism: in which one of the participants, the parasite, either harms or lives at the expense of the host. Intestinal protozoa are spread by the fecal-oral route, so infections are widespread in areas with inadequate sanitation and water treatment.
They are also common in the US in settings where fecal incontinence and poor hygiene prevail, as may occur in mental institutions and day care centers. This section describes the usefulness of patient symptoms and history, as well as laboratory findings, in the diagnosis of infection with an intestinal protozoan.
Pathogenic intestinal protozoa discussed in the section include amebae, flagellates, ciliates, coccidia, and microsporidia. Entamoeba histolytica, which may cause amebic dysentery, is the most pathogenic of the intestinal amebae and.

The examination of a single sample of the faeces of 1, patients at the Institut Pasteur of Lille has shown the presence of all the common intestinal protozoa of man.
Of the persons with Entamoeba histolytica infections, it was noted that 65 per cent. had at one time or another lived in the colonies. The contrary was the case with the giardia infections; per cent. had never left France.
In the introduction it is pointed out that the paper serves as an explanation of the accompanying plate, which represents various appearances of the cysts of the commoner known protozoa found in the human intestine. The author made most of his drawings from specimens mounted in Weigert's iodine solution (=iodine 1, potassium iodide 2, distilled water ).
Cestodes. The life cycle of Echinococcus is shown above. Tapeworms are long, segmented worms of the class Cestoda, which includes the genera Taenia, Diphyllobothrium, Hymenolepis, Dipylidium, Echinococcus, and Spirometra.
[1,2] Adult tapeworms lack an intestinal tract and absorb all nutrients through their integument. The adults have a head (termed a scolex), a neck, and a segmented body.

One of the interesting features of NTZ is the activity of this drug against common intestinal helminths, in addition to protozoans. Controlled trials conducted in Peru demonstrated that the standard three-day course of NTZ in children produces cure rates comparable to a mg single dose of albendazole in ascariasis and to a single dose of
