Phylogenetic reconstruction of subfamily Orthoparamyxovirinae viruses in study of NiV shedding in urine from fruit bats, Sri Lanka, 2018–2019. The alignment is based on the partial large gene (7,977 nt) coding for the RNA-dependent RNA polymerase. Calculation was done using a MrBayes Markov chain Monte Carlo approach of molecular clock reconstruction based on the general time reversible model with the parameters set at 1 million replicates, 4 chains, and burn-in at 10%. Blue shading and green shading indicate distinct genera of paramyxoviruses. Red shading highlights the novel strains from Sri Lanka. Node numbers indicate posterior probability. We used a simian orthorubulavirus as an outgroup. Scale bar indicates branch length. NiV, Nipah virus; P. medius, Pteropus medius.
