tissues. Post-operative wound infection results from
microbial contamination during or after a surgical procedure
(Maclean et al., 1989). Hospital acquired infection includes
infections acquired while the patient is in bO$pital. Surveys
in Britain (UK)Indicated that about half of all the infections.
occuring in hospital inpatients are hospital acquired
(Sanderson and Rogres, 1988). Bacterial colonization of
surgical wounds are either endogenous (from viscera which
contain bacterial or exogenous (from hands of cases,
carriers, instruments or aiii’) {Akoet al., 1992).
Wound sepsis represent a major hazard in health care
facilities. They result in substantial morbidity, prolongation
of hospital stay, an increase in direct patient care costs and
mortality that occur after hospitalization, i.e they are not
present or incubating at the time of admission (Twum et al.,
L992).
Patients in post-operative wards are heavily exposed to
micro-organisms from different sources, but access ’ofthe
organisms ~O. the depth ofthe wound is often limited. If the
