Detection of the zoonotic bacterial pathogen Streptococcus suis was achieved using magnetic glycoparticles. The bacteria contain an adhesion protein for the carbohydrate sequence Galα1,4Gal. After incubation with various amounts of the pathogen, magnetic concentration and ATP detection, bacterial levels down to 105 cfu could be detected. Submicrometer particles were needed, since with the larger microparticles the method did not succeed.
使用磁性糖颗粒实现了人畜共患细菌病原体猪链球菌的检测。该细菌含有
碳水化合物序列 Galα1,4Gal 的粘附蛋白。与不同数量的病原体一起孵育、磁力浓缩和
ATP 检测后,可以检测到低至 105 cfu 的细菌
水平。需要亚微米颗粒,因为对于较大的微粒,该方法不成功。
