Cysticercosis is an infection caused by the larvae of the parasite Taenia solium . This infection occurs after a person swallows tapeworm eggs. The larvae get into tissues such as muscle and brain, and form cysts there (these are called cysticerci). When cysts are found in the brain, the condition is called neurocysticercosis.Correct sampling and identification of nematode populations helps determine the best management practices. Use thresholds mostly as a guide and determine the best course of action by evaluating the entire situation. Sometimes reducing stressors can be enough to manage nematode infestations. If not, small-scale treatments can confirm whether nematodes are causing an issue and which products are ...Due to their high ecological relevance in freshwater, marine, and terrestrial habitats, nematodes are of strong potential interest as environmental indicators (Wilson and Kakouli-Duarte, 2009).Two symposia on "Nematodes as Environmental Bioindicators" 2007 in Edinburgh (United Kingdom) and 2012 in Gent (Belgium) helped to open avenues of communication between various scientists and ...Scalp biopsies are occasionally obtained in children as well, because they may be useful diagnostically in both congenital and acquired alopecias.
