Y1 - 2022 N1 - T2 - Maxcy-Rosenau-Last Public Health & Preventive Medicine, 16e AB - Hydatid disease (echinococcosis) is the infection of humans by the larval stages of taeniid cestodes of the genus Echinococcus. Humans are incidental intermediate hosts for several Echinococcus species, which cause various forms of “hydatid disease,” including cystic echinococcosis (CE), alveolar echinococcosis (AE), and neotropical echinococcosis [which includes polycystic (PE) and unicystic echinococcosis (UE)]. Four species/complexes of Echinococcus are currently recognized, of which three cause distinctive forms of human disease: Echinococcus granulosus sensu lato with cystic echinococcosis (CE), Echinococcus multilocularis with alveolar echinococcosis (AE), and Echinococcus vogeli with polycystic echinococcosis (PE). The fourth species, E. oligarthrus, has only rarely been identified in humans and is associated with unicystic echinococcosis (UE).1 Diverse subpopulations of E. granulosus, distinguished by genetic, morphologic, and biologic characteristics, have long been recognized; the taxonomic significance of these differences remain unresolved and controversial.1 However, recent demonstration of consistent genetic differences has prompted calls for splitting this species. A cause of high morbidity and with capacity for considerable pathology, Echinococcus spp. are collectively some of the most important zoonotic cestodes from a public health standpoint.1,2 SN - PB - McGraw Hill CY - New York, NY Y2 - 2024/03/28 UR - accessmedicine.mhmedical.com/content.aspx?aid=1182666416 ER -
