Several non-pathogenic protozoa inhabit the intestinal. The non-pathogenic protozoa can be divided into two groups: amebae and flagellates. Protozoa are a diverse group of unicellular eukaryotic organisms, many of which are motile. One hundred and ten fecal samples from hemodialysis patients were analyzed, as well as 86 from a community group used as control group. A result of 51.6% of intestinal parasites was observed in hemodialysis patients and 61.6% in the control group. Cryptosporidium and Blastocystis were the most common infections in patients with CRF (26.4% and 24.5%, respectively). Blastocystis was the most common infection in the control group (41.9%), however no individual was found positive for Cryptosporidium.
Prevention of the disease is by separating food and water from faeces and by proper sanitation measures. If present in tissues is treated with either metronidazole, tinidazole, nitazoxanide, dehydroemetine or chloroquine, while luminal infection is treated with diloxanide furoate or iodoquinoline. For treatment to be effective against all stages, it may require a combination of medications. Infections without symptoms do not require treament but infected individuals can spread the parasite to others and treatment can be considered. To help prevent infection:
•Avoid raw vegetables when in endemic areas, as they may have been fertilized using human feces.
•Boil water or treat with iodine tablets.
