Heat map of NELoc-1, -2, and -3 gene distribution among 54 poultry and nine nonpoultry C. perfringens isolates. Microarray CGH results for the genes found in the three NE-associated loci are shown. Each column represents a different strain, and each row represents a different microarray probe. Gene probes called absent are colored blue, green, or red, and undetectable probes are colored gray. The colors indicate nonpoultry strains (blue), netB-negative isolates (green), and netB-positive isolates (red). The nonpoultry strains (from left to right) are SM101, NCTC 8239, F4969, ATCC 3626, JGS1495, JGS1721, JGS1987, ATCC 13124, and Str13. The host disease statuses of the isolate sources are given at the top. Probes are ordered according to the draft CP4 genome sequence, with the start of the genome at the top. See Table S3 in the supplemental material for details on the variable regions.
