Protozoan infection: Protozoan infections are parasitic diseases caused by organisms formerly classified in the Kingdom Protozoa. They include organisms classified in Amoebozoa, Excavata, and Chromalveolata.Intestinal parasiteEffects of parasitic worms on the immune system: The effects of parasitic worms, or helminths, on the immune system is a recently emerging topic of study among immunologists and other biologists. Experiments have involved a wide range of parasites, diseases, and hosts.Soil-transmitted helminthiasis: Soil-transmitted helminthiasis (STH) is a type of helminth infections (helminthiasis) caused by different species of roundworms. It is caused specifically by those worms which are transmitted through soil contaminated with faecal matter and are therefore called soil-transmitted helminths.Small nucleolar RNA-derived microRNA: In molecular biology, small nucleolar RNA derived microRNAs are microRNAs (miRNA) derived from small nucleolar RNA (snoRNA). MicroRNAs are usually derived from precursors known as pre-miRNAs, these pre-miRNAs are recognised and cleaved from a pri-miRNA precursor by the Pasha and Drosha proteins.List of birds of Yemen: This is a list of the bird species recorded in Yemen. The avifauna of Yemen include a total of 432 species, of which thirteen are endemic, two have been introduced by humans and twenty-five are rare or accidental.Free-living Amoebozoa infectionEntamoeba histolytica: Entamoeba histolytica is an anaerobic parasitic protozoan, part of the genus Entamoeba. Predominantly infecting humans and other primates, E.Giardia: Giardia ( or ) is a genus of anaerobic flagellated protozoan parasites of the phylum Sarcomastigophora that colonise and reproduce in the small intestines of several vertebrates, causing giardiasis. Their life cycle alternates between an actively swimming trophozoite and an infective, resistant cyst.Oxymonad: The Oxymonads are a group of flagellated protozoa found exclusively in the intestines of termites and other wood-eating insects. Along with the similar parabasalid flagellates, they harbor the symbiotic bacteria that are responsible for breaking down cellulose.CryptosporidiosisKudoa thyrsites: Kudoa thyrsites is a myxosporean parasite of marine fishes. It has a worldwide distribution, and infects a wide range of host species.Microneme: Micronemes are cellular organs, or organelles, possessed by Apicomplexa protozoans that are restricted to the apical third of the protozoan body. They are surrounded by a typical unit membrane.Blepharisma japonicum: Blepharisma japonicum is a species of protozoans, that can be found either in water or soilHabitat of Japan.PlasmoDB: PlasmoDB is a biological database for the genus Plasmodium. The database is a member of the EuPathDB project.
