Abstract
Femoral heads excised during surgery were obtained from patients who had a fractured neck of the femur and were processed as bone allograft. The bacterial contaminants were isolated from femoral heads at different stages of processing and identified based on morphological characteristics and biochemical tests. Bacterial contaminants on bone were mainly Gram-positive bacilli and cocci (58.3%). Twenty-four isolates from bone samples were screened for resistance to radiation. The D10 values for Gram-negative bacteria isolated from femoral heads ranged from 0.17 to 0.65 kGy. Higher D10 values 0.56–1.04 kGy were observed for Gram-positive bacterial isolates.
