Abstract
In cervico-facial sepsis a substantial proportion of organisms are normally gram-negative
staining of which the majority are anaerobes (Boyanova 2006 and Sanchez 2010). At
Tygerberg Academic Hospital and Tygerberg Oral Health Centre it has been found that patients
treated for cervico-facial sepsis seldom have gram-negative organisms on culture, although the
staining results reported the presence of gram-negative organisms.
The aim of the study was to assess the prevalence of gram-negative staining in a population of
patients with cervico-facial sepsis and to determine the number of gram-negative stains that
yield gram-negative organisms on culture.
Results indicated that 71 out of a possible 90 pus swabs reported a gram stain. Of those, 48
specimens stained gram-negative and only two of these cultured gram-negative organisms.
Although gram-negative organisms are present on gram stain, microbiological diagnosis of
gram-negative organisms on culture was very seldom found at the Maxillofacial and Oral
Surgery unit at the Tygerberg Academic Hospital and Tygerberg Oral Health Centre.
