    Abstract:
    Cryptosporidiosis is a worldwide-diffused protozoan disease causing important economic losses to animal husbandry and livestock production. Additionally, several species/genotypes of Cryptosporidium have a relevant zoonotic potential and ruminants may be important sources of infection for human beings. Nonetheless, in Europe, little is known of the presence of Cryptosporidium in sheep nor on the species/genotypes involved. To obtain information on the occurrence of cryptosporidiosis in lambs and the potential zoonotic role of the Cryptosporidium isolates, one hundred and forty-nine faecal samples individually collected from lambs in central Italy have been examined for the presence of Cryptosporidium. All faecal specimens were processed with a commercial ELISA kit immunoassay and all ELISA-positive samples were further analyzed genetically. Twenty-six ELISA-positive samples scored positive at the PCR and the sequences obtained displayed 100% identity with the zoonotic Cryptosporidum parvum. This work suggests for the first time that lambs in Italy may shed C. parvum, thus representing a potential public health hazard.
