Abstract
Wounds are a significant cause of morbidity worldwide, studies show that
for every million wound patients, at least 10.000 die from microbial infections. The
skin is a vital organ that serves as a protective barrier between the human bodies on its
external environment. Staphylococcus aureus has been known as a cause of deepseated wound infection for close to a century, having recognized as a cause of
nosocomial infection and super infection in patients receiving antimicrobial agent such
as surgical cases. MRSA colonizing the anterior nares and skin of human are the major
sources of surgical site infection as well as nosocomial spread. Methicillin-resistant
Staphylococcus aureus (MRSA) are bacteria resistant to penicillin and cephalosporin
classes of antibiotics and are often resistant to many other classes of antibiotics.
Importance of S. aureus as persistent nosocomial and community acquired pathogen
has become a global health concern. The aim of this study to determine the frequency
and antibiotic susceptibility pattern of S.aureus isolated from wound infected patient
attending Wad Madani Teaching Hospitals. Two hundred samples collected from
patients with infected wound at the period from April to July 2016. Out of 200
samples examined, 60 (30%) isolates of S. aureus obtained, 116 (58%) other bacterial
species and 24 (12%) samples showed no growth. The highest isolation rate of S.
aureus 60% occurred among age group (41-60) and according to gender 32 (53.3%) S.
aureus isolated from male and 28 (46.7%) from female. The overall profile of
susceptibility pattern showed that vancomycin and linezolid were more sensitive
(100%), amoxicillin and penicillin were the least sensitive (10%) and (36%)
respectively. The result of the study showed that frequency of S. aureus isolated from
infected wounds 60 (30%) and vancomycin and linezolid are more effective in the
management of S. aureus in this locality.
