Characterization of Nipah Virus from Naturally Infected Pteropus vampyrus Bats, Malaysia
Figure 2. Partial nucleocapsid gene (358 bp) maximum-likelihood tree for all available Nipah virus (NiV) sequences (seqs) in GenBank, showing a high level of NiV sequence diversity in Pteropus lylei bat isolates from Thailand. NiV P. vampyrus (box) is most closely related to AY858110 from P. lylei bats and forms a large clade that includes other P. lylei bat isolates and all NiV sequences from Malaysia. GenBank accession numbers are given for NiV isolates from pigs in Malaysia (AJ627196, Tambun; AJ564621, Sg. Buloh; and AJ564622, Seremban), humans in Malaysia (AJ564623, AF212302, AY029767, and AY029768), humans in Bangladesh (AY988601), P. hypomelanus bats in Malaysia (AF376747), P. lylei bats in Cambodia (nucleocapsid gene-AY858110, DQ061851–58, EF070182–90, EU603724–58, EU620498, and EU624735–37), and Hendra virus from Australia (AF017149).
