Isolation of Pyogenic Microorganisms from Infected Wounds in the General Surgery and Orthopedic & Traumatology Departments of the Near East University Hospital: A Retrospective Study

Abstract

BACKGROUND/AIMS: Wound infection is characterized as the presence of a wound environment characterized by microorganisms in adequately large numbers, or of adequate virulence to aggregate an immune response locally and/or systemically. The aim of this study, conducted in a university hospital in North Cyprus, was to determine the microorganisms that cause pus formation in wound infections.MATERIALS AND METHODS: One hundred and eighty-five samples were analyzed for this study from the period of September, 2015 to August, 2019. The samples were analyzed in the Near East University Hospital Microbiology Laboratory, North Cyprus. The samples were collected from two different departments. The sensitivity pattern of the organisms was determined by the BD Phoenix instrument. The SPSS version 22 was used for statistical analysis.RESULTS: The orthopedic unit had a total of 123 patient samples while the general surgery unit had a total of 62 patient samples. Culture was positive in 56 (45.5%) of the 123 samples taken from the orthopedic clinic. There was no significant difference between gender and wound infection in the samples taken from the orthopedic clinic (p=0.640). The total number of outpatients was 15 (12.2%) and the number of inpatients was 108 (87.8%) in the orthopedic department. In the general surgery department, there were a total of 62 patient samples and a total of 41 (66.1%) were culture positive. The most commonly seen bacteria was Escherichia coli (22.6%).CONCLUSION: With the aim to determine a summarized analysis of wound microbiology, and the current opinions and controversies regarding wound treatment, this retrospective study attempted to assess the microbiological aspects which are important to the administration of microorganisms in wounds.
