Frequency and Sensitivity Pattern of Aerobic Bacteria isolated from Wounds of Diabetic Patients

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.
