Classification of parasites divided into three main groups: A Protozoa single-celled organism, multiply in human host, All protozoans have 2 important stages of life: Trophozoite and Cyst 1 1- -Sarco a-subphylum: Sarcodina b-subPhylum:mastigophora 2- Phylum: Ciliophora 3- Phylum: Sporozoa B-Helminthes (worms) multicellular worms, do not normally multiply in human host 1- Phylum: platyhelminthes 2- Phylum: Nematoda 3- Phylum: Acanthocephala C-Arthropoda multicellular, do not normally multiply in human host 1- Phylum: insecta 2- Phylum: Archneida Trophozoite and Cyst Sarcomastigophora
Schistosoma is a genus of trematodes, commonly known as blood flukes. They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis Kingdom: Animalia Phylum: Platyhelminthes Class: Trematoda Order: Diplostomida Family: Schistosomatidae Genus: Schistosoma The three main species infecting humans are Schistosoma haematobium Schistosoma japonicum Schistosoma mansoni Schistosomiasis is diagnosed through the detection of parasite eggs in stool or urine specimens. Antibodies and/or antigens detected in blood or urine samples are also indications of infection
Phylum: Nematoda Nematodes that commonly parasites humans includeforv examples ascarids (Ascaris). Ascaris is a genus of parasitic nematode worms known as the "small intestinal roundworms", which is a type of parasitic worm. One species, Ascaris lumbricoides, affects humans and causes the disease ascariasis. Kingdom: Animalia Phylum: Nematoda Class: Chromadorea Order: Ascaridida Family: Ascarididae Genus: Ascaris Species: Ascaris lumbricoides
The standard method for diagnosing ascariasis is by identifying Ascaris eggs in a stool sample using a microscope.
