A review of the current status of Cryptosporidium in fish.

In addition, more than 70 genotypes have been described in different hosts (Ryan I et al i ., 2014; Chalmers I et al. i , 2018; Holubová I et al. i , 2020; Jezková I et al. i , 2021; Zahedi I et al. i , 2021). Other studies have identified different I C. parvum i subtypes in both freshwater and marine fish, including subtypes IIaA13G1R1, IIaA14G2R1, IIaA15G2R1, IIaA16G2R1, IIaA17G2R1, IIaA18G3R1 and IIaA19G4R1 (see Table 3) (Reid I et al i ., 2010; Koinari I et al. i , 2013; Certad I et al. i , 2015, 2019; Couso-Pérez I et al. i , 2019). A lower diversity of I Cryptosporidium i species/genotypes (including I C. molnari i , piscine genotype 10 and I C. parvum i ), although with higher overall prevalences (40.0%; 0.2 and 20.0-100%, respectively), has been identified by molecular methods in freshwater fish from lake Leman (France), Papua New Guinea and Galicia (NW Spain) (see Tables 1 and 2) (Koinari I et al. i , 2013; Certad I et al. i , 2015; Couso-Pérez I et al. i , 2019).
