“…Most studies on piscine Cryptosporidium have involved ornamental fish, including about 70 species collected from various aquariums and pet shops in Perth (Western Australia) (Zanguee et al , 2010 ; Morine et al , 2012 ; Yang et al , 2015 , 2016 ; Palermo, 2016 ; Bolland et al , 2020 ; Zahedi et al , 2021 ) and in different cities in Iran (Nematollahi et al , 2016 ; Shahbazi et al , 2020 ). Cryptosporidium was detected by molecular methods in a total of 12 and 16 species of marine and freshwater ornamental fish, respectively, with prevalences in the range of 9.1–100% in marine fish and 0.9–100% in freshwater species (Zanguee et al , 2010 ; Morine et al , 2012 ; Yang et al , 2015 , 2016 ; Palermo, 2016 ; Bolland et al , 2020 ; Shahbazi et al , 2020 ; Zahedi et al , 2021 ).…”
