Bacterial Infections of Second-Degree Burns and their Antibiotic Resistance Patterns with Residence Time in Al-Hilla General Teaching Hospital, Iraq

Abstract

A healthy skin barrier  is substantial to protect from infection, maintain body liquid balance and regulate heat. A burn lesion damages the external barrier and allows bacterial infection, thus delaynig the  healing of burn's wound. The aim of this study  is to characterize the bacterial flora in second degree burns in  a time period of 4 weeks and testing the sensitivity of  the isolated bacteria to antibiotics .  Samples were collected from burned patients in Al-Hilla General Teaching Hospital over a four-month period from June 2020 to September 2020. The colonization of bacteria to burns wounds was noticed weekly from the time of entry until the fourth week of hospitalization. Periodic swabs  from burns were collected in the first, second, third and fourth weeks of hospital stay. Through the four months of the potential study, a total of 25 patients with a new burn accident at the burn department were investigated . The Enterobacter sp. and Pseudomonas aerugionsa accounted for 33% and 22% respectively of bacteria isolated from burn wounds followed by Klebseilla sp. 12% and Bacillus sp. 38 (17.7%). It was observed that Pseudomonas aeruginosa was predominant among the bacterial isolates in both single and mixed infections  during the examined time. Pseudomonas aeruginosa was the dominant bacteria throughout the study period in particular and most of them were resistant to antibiotics. Amikacin was the selected antibiotic for almost bacteria and was present to have an effectiveness against almost of the isolated bacteria. Current research appears to be useful in supplying beneficial advice for selecting an efficient antibiotics against bacterial isolated from patients with burns
