Some Aerobic Bacteria Associated With External Wounds Of Donkeys In Khartoum State

In the present study 808 donkeys in Khartoum state were investigated for bacterial wound infection. The investigation included isolation and identification of the contaminated bacteria, determination of sensitivity of the isolates to different antibacterial drugs, and evaluation of the methods of treatment used. The relation between some factors (age, sex of animals, type of work, duration of work and site of wound) and the occurrence of wounds was studied. Wounds were detected in 30.8% (249) of the investigated animals and all of them except four were infected with bacteria. Three–Hundred and twenty-two bacterial species were isolated. The isolates were identified as: Rhodococcus spp (31.67%), Staphylococcus spp (31.05%), Micrococcus spp (12.11%), Corynebacterium spp (5.59%), Bacillus spp (4.96%), Streptococcus spp (92.79%), Actinomyces spp (2.79%), Pasteurella spp (1.86%), Pseudomonas spp (1.24%), Neisseria spp (1.24%), Acintobacter spp (0.93%), Fusobacterium spp (0.93%), Listeria spp (0.62%), Brucella spp (0.62%), Actinobacills spp (0.62%), Yersinia spp (0.62%) and Flavobacterium spp (0.31%). Most isolates were found sensitive to gentamicin, chloroamphinicol, lincomycin and ofloxacin. Brucella abortus was resistant to all antibiotics. Rhodococcus equi was resistant to ampicillin and moderately sensitive to tetracycline. The collected data reveled that 45.9% of the wounded donkeys were less than 8 old and 35.54% of them were wounded during summer. Most of the wounds were detected on the back of the animal (71.55%), followed by abdominal region (14.22%) and on the legs (11.5%). There was direct relation between the site of wound and type of work, and most of the wounded animals were either treated with traditional methods and drugs or didn’t receive any treatment
