Technical Abstract: Traditional microscopy techniques are insufficient for identifying species and/or genotypes of Cryptosporidium, and molecular tools such as the polymerase chain reaction (PCR) and gene sequencing are required. Currently, with the help of molecular tools a large number of species and genotypes have been described. In cattle, molecular epidemiology has shown that mainly 4 species of Cryptosporidium infect cattle, C. parvum, C. bovis, C. ryanae, and C. andersoni, each species presenting a different prevalence pattern relative to the age of the cattle. In sheep and pigs, molecular epidemiology has shown 2 species of Cryptosporidium are mainly responsible from most infections, C. xiaoi and C. ubiquitum in sheep, and C. suis and pig genotype II in pigs. The need to precisely identify Cryptosporidium species/genotypes as well as the risk of zoonotic transmission of Cryptosporidium will be discussed in greater detail.
