Phylogenetic tree of faecal coliform bacteria isolated from river water (blue) and riverbed sediment (red) constructed using MEGA 6 with the Neighbor-Joining method-distance Kimura 2, for a 1500Â bp fragment of the 16S rRNA coding region of the Faecal coliform bacteria. Numbers above branches show bootstrap values expressed as percentages of 100 replications and distribution of the genetic profiles isolated from different sites of the Apies River
