Maximum likelihood tree (− ln = 4017.25) based on partial sequences of the 60 kDa glycoprotein gene of Cryptosporidium ubiquitum, Cryptosporidium apodemus genotype I and II and Cryptosporidium chipmunk genotype I, including sequences obtained in this study from naturally infected hosts (red circles and bolded). Tamura’s 3-parameter model was applied, using invariant sites. The robustness of the phylogeny was tested with 1000 bootstrap pseudoreplicates and numbers at the nodes represent the bootstrap values > 50%. The scale-bar indicates the number of substitutions per site. Sequences obtained in this study are identified by isolate number (e.g. 43201)
