Prevalence Of Multidrug-Resistant Bacteria Isolated From Burn Wounds In Algeria

We conducted a thirty-four-month retrospective study in the Burns Center from June 2015 to 30 April 2018. A total of 1585 burn wound swabs were taken from 258 admitted patients, of both sex and average age from 2 to 84 years old. Out of the 1585 burn wound swabs, 79.12% were positive for bacterial growth. Gram-negative bacteria were the most common bacteria isolated from burn wound swabs (68.95%), followed by cocci gram positive (28.62%), which were represented mainly by Staphylococcus spp. and Enterococcus spp. species, and then other species such as candida spp. (2.41%). Staphylococcus aureus was found to be the most common isolate (of the 70 Staphylococcus aureus, 52 were methicillino-resistant MRSA) followed by Pseudomonas aeruginosa (n=58; 25.71%), Klebsiella pneumoniae (n=43; 20.15%), Acinetobacter baumannii (n=18; 18.70%), Proteus spp. (n=17; 7.91%), Escherichia coli (n=14; 5,75%), Enterobacter spp. (n=8; 3.22%), Candida spp. (n=6, 2.41%), Stenotrophomonas maltophilia (n=2; 1.73%), and lastly Enterococcus spp. and Citrobacter freundii (n=1; 1.73%). P. aeruginosa was the most frequent Gram-negative bacteria isolated (33.91%). Most of the species isolated were multidrug-resistant (MDR). Knowledge of the bacteria responsible for infectious complications and their antibiotic susceptibilities is a prerequisite for treating burn patients.
