Fig. 2From: Population genetics of Cryptosporidium parvum subtypes in cattle in Poland: the geographical change of strain prevalence and circulation over timeThe phylogenetic maximum likelihood tree constructed using the nucleotide sequences (294Â bp) of the GP60 gene fragment of C. parvum strains detected in cattle. C. hominis was used as an outgroup to root the tree. C. parvum strains detected in cattle from Poland before 2014 are marked by black diamondsBack to article page
