RT Journal Article T1 A review of the current status of Cryptosporidium in fish A1 Couso Pérez, Seila A1 Ares Mazás, María Elvira A1 Gómez Couso, Hipólito K1 Cryptosporidium K1 Fish K1 Life cycle K1 Species K1 Gentypes K1 Zoonotic implication AB Species of the genus Cryptosporidium (phylum Apicomplexa) infect the epithelium of the gastrointestinal tract of several vertebrate hosts, including humans and domestic and wild animals. In the past 20 years, several studies have focused on Cryptosporidium in fish. To date, a total of four piscine-host-specific species (Cryptosporidium molnari, Cryptosporidium huwi, Cryptosporidium bollandi and Cryptosporidium abrahamseni), nine piscine genotypes and more than 29 unnamed genotypes have been described in fish hosts. In addition, Cryptosporidium species and genotypes typical of other groups of vertebrates have also been identified. This review summarizes the history, biology, pathology and clinical manifestations, as well as the transmission, prevalence and molecular epidemiology of Cryptosporidium in wild, cultured and ornamental fish from both marine and freshwater environments. Finally, the potential role of piscine hosts as a reservoir of zoonotic Cryptosporidium species is also discussed PB Cambridge University Press SN 0031-1820 YR 2022 FD 2022 LK http://hdl.handle.net/10347/29286 UL http://hdl.handle.net/10347/29286 LA eng NO Couso-Pérez, S., Ares-Mazás, E., & Gómez-Couso, H.
