            of different bacteria had high homology, we found differences among Escherichia coli, Pseudomonas aeruginosa, Paenalkaligenes sp., and Stenotrophomonas
            sp. The difference in position with the E. coli gene was indicated by black stars. The bacterial name was known from NCBI BLASTN (National Institutes of
            Health, USA) with derived sequences (not shown here) 14
