Abstract

Pseudomonas aeruginosa is an opportunistic pathogen that can cause different infections such as nosocomial bacterial infection, Urinary tract infection, Meningitis, Eye infection, Otitis Media, Respiratory infections, and Pneumonia, especially in people with Cystic fibrosis, Bone and joints infection, gastrointestinal infection, Skin infection and soft tissue inflammation.  Resistance of P. aeruginosa to antibiotics and disinfectants is a major problem all over the world due to the random and unrestricted use of antibiotics. This resistance is also likely to occur due to several reasons, including the production of beta-lactamase enzymes and the lack of permeability of their cell wall, possibility of it containing resistance genes and the occurrence of genetic mutations leading to the development of resistance to antiseptics and causing failure in treating infections that caused by P. aeruginosa. This study aims to detect and sequence analysis of qacE gene in P. aeruginosa that responds to the resistance of Quaternary ammonium compounds and detect the mutations in this sequence and detection protein synthesis in this gene.  A hundred swabs were collected from patients with burns and wounds infection from many Hospital in Baghdad including Al- Kindi Teaching Hospital, Al-Yarmouk Teaching Hospital, Baghdad Teaching Hospital, National Centre for Educational Laboratories, Al-Shahid Ghazi Hariri Specialist Specialized Burns Centre (Medical City), and Al-Zaafarania General Hospital during the period October 2017 for the end of December 2017.The current study detected 69 isolates of P. aeruginosa from wound 68.6% (24/35) and burn samples 69.2% (45/65). The study was investigated QacE gene in 97.1% that responses of P. aeruginosa resistance to Quaternary ammonium compounds. The sequencing analysis for QacE genes were determined and the results appeared multiple mutations including Missense mutations, insertion mutations and several silent mutations, some mutations effected in the translation of protein while others not affected. This study also included the analysis of phylogenetic tree of QacE gene and the results showed that the tree consisted of only one species which is P. aeruginosa, and the isolates in this study did not deviate of this bacteria even if their mutations were more than 22.
