Clonorchis sinensis under a light microscope: Notice the uterus; this species is monoecious. An adult C. sinensis is a flattened (dorsoventrally) and leaf-shaped fluke. The body is slightly elongated and slender, measuring 15–20 mm in length and 3–4 mm in width. [10]
Specific helminths can be identified through microscopic examination of their eggs (ova) found in faecal samples. The number of eggs is measured in units of eggs per gram . [ 35 ] However, it does not quantify mixed infections , and in practice, is inaccurate for quantifying the eggs of schistosomes and soil-transmitted helminths. [ 36 ]
Carcinogenic parasites are parasitic organisms that depend on other organisms (called hosts) for their survival, and cause cancer in such hosts.Three species of flukes are medically-proven carcinogenic parasites, namely the urinary blood fluke (Schistosoma haematobium), the Southeast Asian liver fluke (Opisthorchis viverrini) and the Chinese liver fluke (Clonorchis sinensis).
The technique used for testing depends on the type of sample. [42] When the helminth ova are in sludge, processes such as alkaline-post stabilization, acid treatment, and anaerobic digestion are used to reduce the amount of helminth ova in areas where there is a large amount. These methods make it possible for helminth ova to be within the ...

The metacercariae are an adapted cystic form dormant in the secondary intermediate host. The adult is the fully developed form which infects the definitive host. The first stage is the miracidium that is triangular in shape and covered by a ciliated ectoderm which is the outermost layer of the three germ layers.
SMU coach Rhett Lashlee took a moment while preparing his team for the College Football Playoff to address the ever-growing concern over the open transfer portal window. Rather, Lashlee's issue ...
O. viverrini (together with Clonorchis sinensis and Opisthorchis felineus) is one of the three most medically important species in the family Opisthorchiidae. [4] In fact O. viverrini and C. sinensis are capable of causing cancer in humans, and are classified by the International Agency for Research on Cancer as a group 1 biological carcinogen ...
