It had been also reported that eDNA originates through the intracellular DNA beneath problems through which lysis is not observed . In situation of Staphylococcus IDO epidermidis  and Enterococcus faecalis , eDNA effects in the autolysin-mediated killing of a compact subpopulation of cells, to provide DNA as being a part of biofilm matrix. A recent review exhibits that eDNA is often launched through autolysis and might be a significant contributor to vancomycin-enhanced biofilm formation in Staphylococcus aureus .Biofilm formation by A. baumannii [19, 20] has facilitated its survival on dry surface and enhanced antibiotic resistance, leading to A. baumannii being a persistent infectious agent in intensive care units (ICUs). Our recent investigation  demonstrates that biofilm formation by A.
baumannii strains on clinical devices, such as urinary catheters, could explain their capacity ref 1 to persist in clinical environments and their position in device-related infections. However, the accessible understanding within the unique molecular determinants inside the development of biofilms inside a. baumannii is scarce. We hypothesize that eDNA can be one such essential determinant. else Though studies on eDNA and its purpose in purely natural transformation in Acinetobacter are actually reported earlier [22�C25], to date eDNA remains an uncharacterized determinant from the pathogenic bacterium A. baumannii. Considering that biofilm formation is often a significant virulence component within a. baumannii, characterization of eDNA from A. baumannii with regard to biofilm growth is worthwhile investigating. On this review, we have now characterized eDNA from a multidrug-resistant clinical strain of a. baumannii and demonstrated its purpose in in vitro biofilm formation on abiotic surfaces. 2. Material and Methods2.1. Bacterial Culture and Development ConditionsA clinical strain of Acinetobacter baumannii AIIMS 7, previously isolated , was used in this review.
