Phylogenetic tree. The 16S rRNA gene neighbor joining phylogenetic tree based on 500 bp nucleotide sequences from Escherichia coli and Shigella isolated from wildlife and domestic animals. The tree was constructed using mega 6 using 1000 bootstrap replicates as confidence interval. The color codes represent origin from the same animal species. The isolates under study were separated into two clusters namely A and B, with cluster A having only 2 isolates from wild animals (buffalo and ostrich) while cluster B was divided into minor clusters B1 and B2 with B2 further dividing into B2a and B2b and most isolates were in this cluster.
