Abstract
This study aims to determine the contamination rate of cadaveric bone allograft and blood cultures retrieved from 119 donors within Leicester between 1990 and 2003. A contamination rate of 27% was present, with 120 of 437 bone allografts culturing positive at the time of retrieval. Similarly, a contamination rate of 37% was present, with 40 of 107 blood samples culturing positive. The time interval between death and procurement did not influence blood contamination. Coagulase-negative Staphylococcus was the commonest organism isolated in both blood and bone cultures. One donor had Clostridium grown in their blood culture. The available evidence confirms similar contamination rates with other studies. The majority of organisms isolated were skin commensals with a low rate of contamination of highly pathogenic organisms such as Clostridium.
Résumé
Cette étude a pour but de déterminer le taux de contamination des allogreffes osseuses cadavériques et des hémocultures chez 119 donneurs, entre 1990 et 2003, à Leicester. Un taux de contamination de 27% était présent avec 120 des 437 allogreffes avec une culture positive au moment du prélèvement. De la même façon, un taux de contamination de 37% était présent avec 40 des 107 prélèvements de sang avec une culture le positive. L’intervalle de temps entre la mort et l’acquisition du prélèvement n’a pas influencé la contamination du sang. Le staphylocoque coagulase négative était l’organisme plus fréquent isolé dans le sang et dans l’os. Un donneur avait un Clostridium dans l’hémoculture. Les résultats confirment des taux de contamination voisins de ceux des autres études. La majorité des organismes isolés sont des commensaux de la peau avec un bas taux de contamination d’organismes hautement pathogènes tels que Clostridium.
