Abstract：
In today\'s age of ecological transition, the use of materials such as renewable wood in construction is particularly relevant, but also a challenge in the healthcare sector where the hygiene dimension also comes into play. In this study we have investigated the survival of multi-resistant bacteria commonly responsible for healthcare-associated infections (HAIs) (ESBL-positive Klebsiella pneumoniae and glycopeptide-resistant Enterococcus faecalis) on two different types of wood (Douglas fir : Pseudotsuga menziesii and Maritime Pine : Pinus pinaster) compared to other materials (smooth: stainless steel and rough: pumice stone) and the effect of a disinfection protocol on the bacterial survival on Pseudotsuga menziesii. Approximately 108 bacteria were inoculated on each material and bacterial survival was observed over several days (D0, D1, D2, D3, D6, D7 and D15). Each analysis was performed in triplicate for each time and material. The results show an important reduction of the bacterial inoculum for Klebsiella pneumoniae and Enterococcus faecalis on Douglas fir, in contrast with the results obtained on maritime pine, stainless steel and pumice stone. No bacterial survival was detected on Douglas fir after application of a hospital disinfection protocol. These different results show that wood may have a place in the future of healthcare construction. Further studies would be interesting to better understand the different properties of wood.
摘要：
在当今的生态转型时代,在建筑中使用可再生木材等材料尤其重要，但也是医疗保健部门的挑战，卫生层面也起作用。在这项研究中，我们调查了通常负责医疗保健相关感染（HAIs）（ESBL阳性肺炎克雷伯菌和糖肽抗性粪肠球菌）在两种不同类型的木材（花旗松：Pseudotsugamenziesii和MaritimePine：Pinaster）上的多重耐药细菌的存活与其他材料（光滑：不锈钢消毒和粗糙：浮石）相比，以及Pseudeot在每种材料上接种大约108个细菌,并且在几天内观察到细菌存活(D0、D1、D2、D3、D6、D7和D15)。对每个时间和材料一式三份进行每个分析。结果表明，道格拉斯冷杉上肺炎克雷伯菌和粪肠球菌的细菌接种物大量减少，与在海洋松上获得的结果相反，不锈钢和浮石。应用医院消毒方案后，在道格拉斯冷杉上未检测到细菌存活。这些不同的结果表明，木材可能在未来的医疗保健建设中占有一席之地。进一步的研究将有助于更好地了解木材的不同特性。
