Results of microarray-based comparative genomic analyses of four non-O1, non-O139 strains with the O1 El Tor sequenced strain used for array constriction, N16961. Representation of absent (white) and present (black) genes was based on fluorescence intensity ratios compiled from multiple slides from each strain, and was included alongside previously published data for O1 classical, environmental, and O139 strains for comparison.
