analyzed.Results Thewoundinfectionratewas6.23%afterorthopaedicsoperations.Themain
pathogenswereGram-negativebacteria ( 65% ), thenextwasGram-postivebacteria ( 32% ), and
therateoffungusinecftionwas3%.Thetop7pathogenswerestaphylococcusaureus ( 27.87% ),
pseudomonasaeruginosa ( 23.87% ), enterobactercloacae ( 12.25% ), escherichiacoli (
11.30% ),
