Shahla Najim Abed Al-Azzawi 1 , Rana Mujahid Abdullah 2 1,2 Department of Biology, College of Education for Pure Science (Ibn Al-Haitham), University of Baghdad, Baghdad, Iraq. 1 shahlanajim33@gmail.com, 2 dr.rana_alshwaikh@yahoo.com Abstract A total of 69 isolates of Pseudomonas aeruginosa were obtained from different clinical samples including wounds 24 (35%) and burns 67 (65%)، the genes that responsible for Pseudomonas aeruginosa resistance isolates was detected, the results showed that quaternary ammonium compound delta 1 (qacE∆1) gene was 97.1% in Pseudomonas aeruginosa isolation. 24 (35%) in the wounds and 63 (62.31%) in burns, the size of the gene showed 285 bp, the results of the qacE∆1 analysis showed a single mutation of the mutation type. The results of genetic analysis tree were showed after comparing presence of genetic variations of the qacE∆1 gene with their relatives from the nucleotide sequences as containing variations occurring at one distance and equally in Pseudomonas aeruginosa and other bacterial species. Keywords: Pseudomonas aeruginosa, qacE∆1, Sequencing analysis. DOI: http://doi.org/10.32894/kujss.2019.14.3.2
