Isolation and Identification of Some Bacteria Contemn in Burn Wounds in Misan, Iraq

The current study aimed to isolate and identify the bacteria associated with burn wounds and investigate the antimicrobial susceptibility pattern against a group of most commonly prescribed antibiotics. In total, 105 burn wound swabs were collected from burn patients admitted to the burn unit of Al-Sadr Teaching Hospital in Misan City, Iraq. The swabs had been cultured on different media; the colonies were diagnosed based on the phenotypic and culture characteristics. The bacteria were identified through cultural characters and Gram staining diagnosed by VITEK^® 2 Compact Automated Systems. In total, there were nine distinct bacterial isolations, of which, Pseudomonas aeruginosa was the most common pathogen [20%] followed by Staphylococcus aureus [17.14%], Enterobacter spp.[16.19%], Proteus vulgaris [13.33%], Proteus mirabilis [10.47%], Escherichia coli [7.6%], Klebsiella pneumoniae [6.6%], and at last, Staphylococcus lentus and Aeromonas sobria, which had the same percentage [4.7%]. Most isolates showed high resistance to Tobramycin, Trimethoprim, Cephalothin, and Imipenem while isolates mostly had high susceptibility to Amikacin, Cefotaxime, and Ciprofloxacin. Wound burn infection still represents a serious problem for burn patients with many bacteria developing different degrees of resistance to most known antibiotics.
