Abstract

In   this  study  eight  hundred  sample  of  (wound,  burn,  cystic  fibrosis)  were  collected  from  patients  admitted  to  Emergency hospital,  Hawler  teaching hospital,  Pediatric hospital  and  private  laboratory in Erbil  during  the  period  of  February  2011  to September   2011.  One hundred isolates of  Pseudomonas aeruginosa  were  identified  by using  cultural,  morphological   characteristics,  biochemical  test  and  Api  20NE  system  in  addition  to  vitek  machine. Results of pigments production revealed the ability of P.  aeruginosa to produce various pigments including blue / green, yellow/ green , and brown/ blue .    The  susceptibility of P.  aeruginosa isolates  to  different  antibiotics  was  examined.  Impenim  was  the  most  effective  antimicrobial  agents   against  P. aerugionsa  isolates  and  most   of  isolates  showed  high  resistance  degree  to  doxycycline 100%,  Tetracycline  100%, Vancomycin 100%, Rifampcin 96%, Ampicillin 95%, Chloramphenicol 94%,  Trimethoprim 83%,  Amoxacillin 81%,  Streptomycin 76%, Ceftriaxone  73%, Amikacin 67%,  Cefotaxime 62%,  Gentamycin  54%, and  Ciprofloxacillin 40%.  Due  to  the  resistance  of  the  isolates  to  these  antibiotics  they  were  classified  into   twenty  five  groups that  showed  the  sensitivity  variation  in  their  resistance  to  these  antibiotics. All  P. aerugionsa  isolates  were  screened  for  their  ability  to  produce  B- lactamase  &  Extended  spectrum  Beta  lactamase  out  of  69  of   P. aeruginosa isolates  69%  were  found  to  produce  β-lactamase   using   rapid  iodometric    method  ,  while  48%  of  the   isolates    were   found  to  produce   ESBL. The  plasmid   profile  for  nine  P. aerugimosa isolates  which  showed   the  highest  antibiotic  resistance  were  conducted  and  the  results  revealed   that  all  isolates  except   p6,  and  p8  contain  one  band  with  molecular  weight  more  than  10kb  using  Agarose  gel  electrophoresis  technique.  The  ability  of  P. aerugionsa  to  produce  biofilm  were  studied ,  and  the  results  showed  that  An  among  97%  of  the  isolates  71%  were  strongly  biofilm  producer,  20%  were  moderately biofilm  producer, and  6%  were  weakly  produce  biofilm  while  3%  were  non  biofilm  producer
