Detection of the some dominant aerobic microorganisms in burn injury and testing their susceptibility for different antibiotics in Najaf

Abstract

Burn injury and wound is a pig problem that assists the pathogens to grow and cause infection. 149 burn injury swabs were taken from different site of the patients’ body ages (11-53 years old). All samples were tested to isolate the sigificant microorganisms that found in burn injury. Antibiotics test was performed by using disc diffusion way that stated by Kirby-Baucer. Results appeared that the most frequent pathogen in burn injury was Pseudomonas aeruginosa 33(22.14%) and followed by E.coli 31(20.8%), Staphylococcus aureus 28(18.79%), Proteus vulgaris 26(17.48%), Coagulase-negative Staphylococci 12(8.05%), Proteus mirabilis 10(6.71%), Klebsiella pneumonia 5(3.35%) and Candida spp. 4(2.68%) respectively. Antibiotic test showed that Staphylococcus aureus was a high resistance against Gentamycin and ciprofloxacin, but it was sensitive to Vancomycin and Imipenem. Coagulase negative Staphylococci showed a resistance to Gentamicin, Ciprofloxacin and Ceftazidime, but it was sensitive to Amikacin, Oxacillin, Cefotaxim, Vancomycin, Imipenem and Cefepime. P. aeruginosa showed resistance against Cefotaxime, Aztreonam, Gentamicin and Ceftazidime. Whlist it showed a high sensitivity against Imipenem, Cefepime and Tobramycin. E.coli showed a high resistance against Ceftriaxone, Ciprofloxacin and Cephalothin. whilst it showed a high sensitivity against Ticarcillin/clavulanic acid, Imipenem, Cefepime and Tobramycin. Proteus vulgaris showed a high resistance against Ceftriaxone, Ceftazidime, Amikacin, Cephalothin and Gentamicin. Whilst it showed a high sensitivity against Cefotaxime, Aztreonam, Ticarcillin/clavulanic acid and Imipenem. Proteus mirabilis showed resistance against Amikacin, Ciprofloxacin, Ceftriaxone, Gentamicin and Cephalothin. Whilst it showed a high sensitivity against Ceftazidime, Cefotaxime, Aztreonam, Ticarcillin/clavulanic acid, Imipenem, Cefepime and Tobramycin. Klebsiella pneumonia showed resistance against Ciprofloxacin, Ceftazidime, Cefotaxime and Aztreonam. whilst it showed a high sensitivity against Ceftriaxone, Amikacin, Gentamicin, Cephalothin, Ticarcillin/clavulanic acid, Imipenem, Cefepime and Tobramycin. The current study was aimed to determine the most frequent pathogens in burn injury and test their antibiotics susceptibility in hospitalize patients in Najaf city.
