Freeze-Dryer

我们是来自猪传染病研究组和蒙特利尔大学兽医学院加拿大牛乳腺炎研究网络的研究人员。我们研究一些微生物，细菌，如何在动物和人类中引起疾病。我们研究的细菌包括大肠杆菌、猪链球菌、产气荚膜梭菌和金黄色葡萄球菌。我们正在发现这些微生物用来引起疾病的武器，并了解它们是如何工作的。这项研究导致新的诊断工具和新的策略来控制感染（如药物或疫苗）。我们正在使用和维护大量的动物源性细菌病原体。冷冻干燥允许这些细菌病原体的长期和安全储存。我们要求的这台新的冷冻干燥机是要替换1987年买的那台。我们目前的冷冻干燥机已达到其使用寿命周期，没有更多的备件可用于修复它。此外，在我们的校园里没有其他类似的仪器。延迟更换设备将暂停兽医学院内所有研究项目的所有细菌菌株和突变体保护。丢失宝贵和独特的生物材料的风险很高。因此，迫切需要更换这一设备，因为大量研究人员及其受训人员将使用这一设备。

We are investigators from the Research Group on Infectious Diseases of Swine and from the Canadian Bovine Mastitis Research Network of the Faculté de médecine vétérinaire of Université de Montréal. We study how some microbes, bacteria, cause diseases in animals and humans. We study bacteria such as Escherichia coli, Streptococcus suis, Clostridium perfringens and Staphylococcus aureus. We are discovering the weapons that these microbes use to cause diseases and learning how they work. This research leads to new diagnostic tools and new strategies to control infection (such as drugs or vaccines). We are using and maintaining a huge collection of bacterial pathogens of animal origin. Freeze-drying allows for long-term and safe storage of these bacterial pathogens. This new freeze dryer we are requesting is to replace the current one bought in 1987. Our current freeze dryer has reached its end-life cycle and there are no more spare parts available to fix it. Furthermore, there is no other instrument like this on our campus. A delay in replacing the equipment would suspend all bacterial strains and mutants safeguarding for all research projects within the Faculté de médecine vétérinaire. There will be a high risk of loosing valuable and unique biological materials. There is therefore an urgent need to replace it. This equipment will be used by a large number of researchers and their trainees.
