Australian National Genomic Information Service (ANGIS), including the database of BioManager, has been maintained for a long time by Peter Reeves, a professor at the University of Sydney.
Professor Reeves is internationally renowned for his genetic analysis of enteric bacteria. He determined the genetic basis of the enormous variation in O antigens. There can be more than an I00 form within a species and little overlap between related species. This variation is due to the reassortment of genes between O antigen genes and other gene clusters and the transfer of gene clusters between species. He showed that the 7th pandemic clone of Vibrio cholerae did not arise directly from the 6th pandemic clone, suggesting it arose from an environmental strain, with implications for the origins of this significant human pathogen.
