Abstract

This study includes isolation and diagnoses of some aerobic bacteria contaminated the post –
operative wounds from wounds infection ,100 samples were collected from surgery units of
teaching Hospital, and AL-Samawah General Hospital during Sep 2014 to February 2015, then
the samples cultured on various media (Blood agar, MacConkey agar, chrom agar). Our results
showed that from 100 samples included, 73 (73%) had growth and 27 (27%) had no growth.
Our result reported that S. aureusas the commonest isolate at percentage (23.2%), followed by
Staphylococcus epidermidis (20.6%), Escherichia coli (12.3%), Pseudomonas aeruginosa,
Proteus mirabil, Klebsiellapneumoniae (8.2%), Enterococcus faecalis (6.8%), Citrobacter sp
(2.7%) and Klebsiella oxytoca,b Serratiamarcescens, Acinetobacter sp at percentage (1.4%).
Fomites should be regarded as a possible source of since bacteria from them can be carried
from the hands of theatre personnel to the patient undergoing surgery or through redispersed
bacteria from surfaces during surgery.
