Figure 4From: Molecular analysis of subtilase cytotoxin genes of food-borne Shiga toxin-producing Escherichia coli reveals a new allelic subAB variantSequence analysis and phylogenetic distribution of subA alleles from different genomic loci. Phylogenetic analyses were performed after sequencing and sequence analysis by the software Mega 5.1 using the UPGMA algorithm [28]. Results of the phylogenetic analysis demonstrate clustering of all subA genes according to their genomic loci with exception of subA 2-2 of strain LM27564 which is located in the region between subA 2-1 and subA 2-2 .Back to article page
