Abstract

Ngaingan virus (NGAV) was isolated from a pool of biting midges that were collected in the tropics of northern Australia. Reported here is the full-length sequence of the NGAV genome, which, at over 15.7 kb, is the largest in any rhabdovirus described to date and contains 13 genes, the highest number of genes observed in any (-) ssRNA virus. Seven of these putative genes show no significant homology to known proteins. Like viruses in the genus Ephemerovirus, NGAV possesses a second glycoprotein gene (G(NS)). Phylogenetic analyses, however, place NGAV within the yet to be classified "Hart Park" group containing Wongabel and Flanders viruses, which do not contain a second glycoprotein gene. Screening of various animal sera from northern Australia has indicated that NGAV is currently circulating in macropods (wallabies, wallaroos and kangaroos), highlighting the need for further studies to determine its potential to cause disease in these species.
