Figure 1 in Hepatozoon spp. in stray cats from the metropolitan area of Rio de Janeiro, Brazil
Figure 1. Phylogenetic tree showing relationships between isolates obtained in the present study and sequences used in the recent evolutionary analysis on Hepatozoon felis (Panda et al., 2024 [46]). The evolutionary history was inferred by using the Maximum Likelihood method and Hasegawa-Kishino-Yano model. The tree with the highest log likelihood (—783.89) is shown. The percentage of trees in which the associated taxa clustered together is shown above the branches. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. This analysis involved 58 nucleotide sequences, and there was a total of 184 positions in the final dataset.
