a217 Cryptosporidium-positive animals, but the total number of Cryptosporidium-positive samples is 223 because of five samples with both C. parvum-like species and C. andersoni at microscopy and one sample positive for C. andersoni at microscopy, but for C. bovis, at DNA analysis, are counted twice
bSamples with C. parvum-like oocysts of unknown species (not used for DNA analysis or DNA analysis failed)
cSamples were not analysed for presence of rotavirus, coronavirus or E. coli F5+
dMicroscope analysis, could not be confirmed by DNA analysis
eOne sample positive for C. bovis at DNA analysis, but only a few C. andersoni oocysts detected by microscopy
