Fig. 3 in Molecular identification and phylogenetic analysis of Cryptosporidium, Hepatozoon and Spirometra in snakes from central China

Fig. 3. Maximum likelihood phylogenetic tree of Spirometra based on the cox1 gene. The tree was constructed with the cox1 sequences (444bp) by using the Kimura 2-parameter model with MEGA 7.0; we calculated bootstrap values with 1000 replicates. The representative sequence of Spirometra spagarnas isolated from snakes in this study are in bold print and marked by circles. Scale bar indicates nucleotide substitutions per site.
