Genetic characterisation of in dairy cattle and calves during the early stages of a calving season.

is a causative agent of cryptosporidiosis, an infectious gastroenteritis in neonatal ruminants, which can be fatal in severe cases. The aim of this study was to determine the prevalence of infections in dairy cattle/calves during the early stages of a calving season and the species/genotypes of the present. Faecal samples collected from pre- and post-partum dams ( = 224) as well as calves from age ∼1 day onwards ( = 312) were examined.
