Ranaviruses are rapidly emerging pathogens of ectothermic vertebrates. They have caused morbidity and mortality events around the globe for animals in both captivity and the wild. These viruses have been implicated in the decline and local extinctions of several species and are known to affect several endangered species. Therefore, it is important to analyze the phylogenetic relationships between the different species of Ranavirus to best address the threat that each may pose in certain circumstances. In this study we compare phylogenetic trees built using both the eukaryotic initiation factor 2 homologue (eIF2-α) and the putative tyrosine kinase protein to trees built using the major capsid protein (MCP) and whole genome sequences of 18 different ranaviruses. It was found that trees built using the putative tyrosine kinase protein and the eIF2-α homologue should not be used as alternatives to trees built using the MCP, because the phylogenetic relationships conveyed in the MCP tree are better supported. However, the putative tyrosine kinase and the eIF2-α homologue trees may still provide novel evolutionary information if used in more specific studies. These trees do show a few greatly supported branches, and therefore, could be used select studies and perhaps in conjunction with other genes.
