Colonization of barley plants by the food-borne pathogens Salmonella enterica serovar typhimurium and three Listeria spp. (L. monocytogenes, L. ivanovii, L. innocua) was investigated in a monoxenic system. Herbaspirillum sp. N3 was used as a positive control and Escherichia coli HB101 as a negative control for endophytic root colonization. Colonization of the plants was tested 1-4 weeks after i...

The process of surface sterilizing plant materials is a difficult step in constructing tissue culture technique. Nodal explants from potted plants Solanum tuberosum L. grown the screenhouse were given various sterilization procedures before being introduced into sterile Murashige and Skoog (MS) culture. A total 16 treatments performed with varied periods immersion two sterilant successions: 70%...

Objectives To assess the effect of two of the most commonly used sterilization techniques on 3D printed clinical objects. Materials & Methods The two sterilization methods used in our hospital and investigated in this paper are: Steam heat and Gas plasma. Three objects were printed and tested in this study: a tooth replica, an orthognathic final splint, a surgical cutting guide for the purpos...

The passage of the Virginia Sterilization Act of 1924 [4] demonstrates how science has been used to drive policy throughout history. In the case of the Virginia sterilization [5] law, the science used to draft the law was based on the principles of eugenics [6]. With the help of Harry Laughlin?s Model Sterilization Law [7], the state of Virginia was able to pass its own law allowing sterilizati...
