Dissemination and Molecular Characterization of 16s Rna Methylase and Aminoglycoside Modifying Enzymes- Producing P. Aeruginosa Isolated from Burn Specimens in Najaf City
Background: Pseudomonas aeruginosa is a significant species of bacteria connected with nosocomial infections involving, pneumonia, infections of urinary tract, and damage of the surgical site. Aim of the Study: The aim of this thesis is to investigate the occurrence of genes encoding clinically important 16S rRNA methylases and AMEs enzymes in aminoglycosides resistance P.aeruginosa isolates recovered from Najaf hospitals and the characteristics of these isolates. Methods: a total of 68 specimens were isolated from patients at burn center in Najaf City from the whole study period. The 24 isolates were screened for the sensitivity versus 3 various antibiotics disks of the one class by using Kirby-Bauer disk diffusion method. Results: The resistance rate of 24 isolates of XDR Pseudomonas aeruginosa against aminoglycoside groups: gentamicin, amikacin, and tobramycin were 91.6 %, 83.3 %, and 66.6 %, respectively. However, the resistance profiles of the isolates show that 22 (91.6 %) were resistant to 1 or more antibiotics of aminoglycoside. Present study show that only 3 (12.5%) of XDR isolates harbored ant(4')-IIb gene isolates and none of the XDR isolates investigated were positive for rmtA and aac(6')-IIb gene. Conclusions: This survey has showed for the initial time three isolates harbors the ant(4')-IIb aminoglycoside resistance genes in Iraq.
