Abstract: he study includes the collection of 70 burns and wound swabs from patients of different hospitals, in Baghdad area, for the period from November 2013 to February 2014. 2) 31 isolates characterized as Pseudomonas aeruginosa 9 (45%) from wound and 22 (78.57%) from burn swabs, depending on the characteristics of the colonies phenotypic and microscopic when grown in differential selective media, as well as biochemical tests todiagnose isolates, Then the identification of these species were confirmed by using the system (GN I Card) using Vitek 2 device complementary step.3) The study includes sensitivity test towards 16 antibiotics for each species by using the system (AST Card) using Vitek 2 device, and the isolates ware Multi drug resistance, As results all isolates were resistant by 100 % for each of Piperacillin, Ticarcillin, Ticarcillinclavoulanic acid, Cefazolin, Ceftriaxone and Tigecycline. All strains were less resistance to Ceftazidime with percentage 50%. 4) All the isolates of Pseudomonas aeruginosa with percentage %100, have ability to produce protease enzyme.5) This study was use tow methods of biofilm formations seen in P. aeruginosa, Micro - titer plate method (MTP) and Tube method (TM), Results revealed that MTP was found to be more sensitiveand specific method for biofilm detection than TM. 6) Well diffusion method revealed the inhibitory effect of bacteria Lactobacillus acidophilus, Lactobacillus rhamnosus GG and its supernatants in the growth of bacteria Staphylococcus aureus and P. aeruginosa, and was the supernatant of L. rhamnosus GG isthe largest inhibitory effect on the growth of S. aureus and P.aeruginosa with inhibition diameter 32 and 34 mm respectively, while the inhibition of growth by supernatant of L. acidophilus diameter 25 and 27 mm respectively. 7) Estimated the amount of protein in each of the biosurfactant and bacteriocine producers of L. rhamnosus GG bacteria concentration of 74, 54 Mg/mL respectively, while their concentration in bacteria L. acidophilus 44, 40 Mg / mL, respectively.8) Found that the bacteriocine product of bacteria L. rhamnosus GG and L. acidophilus GG have inhibitory effect on ability of P. aeruginosa to produce the enzyme protease, and the absence of this effect in the Biosurfactants the product of these two types.9) The biosurfactant product from L. rhamnosus GG showed inhibitory effect greater than the effect of the biosurfactant product from L. acidophilus to inhibition (production of biofilm and adhesion to epithelial cells).10) studied the suspension's effect of L. acidophilus and L. rhamnosus GG in contrived injuries wounds in mice contaminated with P. aeruginosa, Positive results have been shown to be affected by the contaminated bacteria injuries wounds.
