Cryptosporidium nasorum among mugil cephalus and tilapia zillii from three different localities in Egypt

In order to add data on fish cryptosporidiosis in Egypt, the present work was conducted on 213 fish [Mugil cephalus and Tilapia zillii] collected from Mediterranean Sea [Port Said], Suez Canal [Ismailia] and Fayoum [Lake Quarun] during the period from June to November 1996. Cryptosporidium nasorum was recorded from 27.23% of them. Crosstransmission of this pathogen to chicken host failed. Furthermore, the present work confirmed the impossible transmission of C. parvum to the lower vertebrates [fish]
