Frequency of exofoliative toxine genes among staphylococcus aureus isolated from burn infection patients in the Specialized Centre for burns of Al – Diwaniyah city

Abstract

Background: Exfoliative toxins (ETs) of bacterium Staphylococcus aureus are the main cause of infections in skin burns. This research sought to determine the frequency of the eta(exofoliative toxine A) gene, etb(exofoliative toxine B) gene and etd(exofpliative toxine D) gene in the S. aureus..
Methods: Between January 2021 and December 2021, 155 S. aureus isolates were gathered from burn sample patients at the Al-Diwaniyah Specialized Burns Center. The polymerase chain reaction was utilized to identify the eta gene , etb gene and etd gene found in the isolates after the species had been established using conventional diagnostic techniques.
Results: Overall, Of the 155 isolates, 25(16.1%), 19(12.2 %) and 44(28.3 %) stated the eta gene, etb gene and etd gene, correspondingly. adding, 20(12.9%) isolates expressed both the eta gene and etd gene, and 16(10.3 %) isolates carrying the etb gene and etd gene, were the eta gene, etb gene and etd gene detected in 33(21.2) .
Conclusion. Because it is likely that these genes will spread and move between strains, the discovery of the extraordinary prevalence of Exofoliative toxines genes in the present study is regarded as a thoughtful issue. Additionally, these community-wide spread isolates are crucial for maintaining good health.
