Abstract:
The main aim of this study was to isolate the possible aerobic bacterial
pathogens from infected wounds of diabetic and non-diabetic patients.
Therefore, a total of fifty specimens were collected from Jabir Abulezz
Center for Diabetic Disorders, Khartoum Teaching Hospital, and Omdurman
Military Hospital. Samples were collected from both males and females at
different ages and then cultured and incubated at 37 oC for overnight. Isolated
bacteria were identified by Gram stain and biochemical tests.
The most common isolated aerobic bacteria among the diabetic patients
were Proteus mirabilis (19%), while S. aureus were the most frequent aerobic
bacteria (42.1%) isolated from non-diabetic patients. The study showed that
among diabetic patients, infection of females were fairly high (57%) compared
to male patients (42%). However, frequency of infection was higher among
non-diabetic male patients (73.6%) than female patients (26.3%). The study
revealed that elder age patients (51-70 years) were more affected by bacterial
infections among diabetic patients compared to non-diabetic patients of the
same age. The antibiotic susceptibility patterns of the bacterial isolates were
similar among diabetic and non-diabetic patients. Most of the isolated bacteria
were sensitive to ciprofloxacin and gentamicin. Furthermore, the results
showed that all isolated bacteria were resistant to ampicillin and to tetracycline
with exception of S. aureus.
In conclusion, diabetic patients were more susceptible to bacterial
infection than non-diabetic population, and most of the isolated aerobic bacteria
were sensitive to ciprofloxacin and gentamicin.
