Phylogenetic analysis of a frog virus 3-like ranavirus found at a site with recurrent mortality and morbidity events in southeastern Ontario, Canada: partial major capsid protein sequence alone is not sufficient for fine-scale differentiation.

Ranaviruses are emerging pathogens of amphibians. We examined the phylogenetic relationship of ranaviruses from infected Lithobates sylvaticus tadpoles 2001-2004 from Oliver Pond, Ontario, Canada. The isolates sequenced are primarily frog virus 3-like, but because of sequence convergence, finer-scale analysis based on the major capsid protein was uninformative.
